What Are Running Boards on a Truck or SUV? Uses, Benefits and Fitment Tips

A cracked bumper. A worn brake pad. A headlight that's finally given out. Whatever the repair, the same fork in the road shows up: go with the original part or try aftermarket instead. For drivers in Warrenton, Astoria, Seaside, and other Oregon Coast towns, that choice affects fit, warranty coverage, and how the vehicle performs down the road. This guide breaks down what separates OEM parts from aftermarket alternatives, so you can make a confident call the next time your Toyota, Jeep, Ram, or Dodge needs a repair. You can also order parts online or connect with our service department if you'd rather skip ahead. OEM vs. Aftermarket Parts: What Warrenton, OR Drivers Should Know OEM stands for original equipment manufacturer, meaning the part comes from the same company that built your vehicle. Aftermarket parts, by contrast, are made by outside companies that never touched your car on the assembly line. Both categories serve real purposes, and neither one is automatically the right answer for every repair. The decision often comes down to what part you're replacing, whether your vehicle is still under warranty, and how long you plan to keep the car. What Are OEM Parts and Why Fitment Matters OEM parts are built to the exact specs of the vehicle they're designed for, which matters more than most people realize until something doesn't line up right. A bumper that's off by a few millimeters, or a filter that seals slightly wrong, can cause bigger headaches later, from uneven wear on neighboring components to reduced efficiency. Because these parts are made to match the original engineering, they tend to install cleanly and perform the way the vehicle was designed to perform. OEM parts also typically come with a manufacturer warranty, giving owners a layer of protection that aftermarket options don't always match. How OEM Parts Are Engineered to Match Your Vehicle's Specs Every OEM part goes through a manufacturing process built around the original vehicle's blueprints, matching the same materials, dimensions, and performance thresholds as the factory version. Manufacturers test these parts to confirm they hold up under the same conditions the vehicle was designed to handle, which helps preserve the car's overall integrity over time. A part built to the same tolerances as the original is simply more likely to behave the way the rest of the vehicle expects it to. Toyota Genuine Parts and Mopar Genuine Parts Explained Toyota Genuine Parts are engineered to Toyota's own standards for quality, performance, and durability, covering brake pads, filters, wiper blades, and specialized components alike. Toyota builds these parts to hold up to its own internal standards for durability and performance, which is why so many owners specifically look for genuine Toyota parts when a repair comes up rather than settling for a generic substitute. Mopar plays the same role for CDJR vehicles. As the OEM provider for Chrysler, Jeep, Dodge, Ram, and FIAT, Mopar parts are designed by the same engineering teams responsible for the vehicles themselves. Mopar's lineup covers brake components, filters, spark plugs, and factory accessories, all built for a fit that matches the vehicle's original specs. What Are Aftermarket Parts and How They Differ An aftermarket part is simply one made by a company other than the original manufacturer. That's a broad category, covering everything from well-engineered replacement parts to budget options that cut corners somewhere along the way. Aftermarket parts are often designed to mimic OEM parts in form and function, but they may not always match the exact measurements of the original component, and that gap in consistency is what drivers need to understand before buying. Variety in Quality, Purpose, and Budget Across Brands Walk into any parts store and you'll find a wide range of aftermarket brands at different price points and quality tiers. Some aftermarket manufacturers specialize in performance upgrades, others focus on affordable replacements for high-turnover items like wiper blades or cabin filters. This range gives drivers flexibility, but it also means research matters. Not every aftermarket brand holds itself to the same standard, so knowing what you're buying is part of the process. Potential Benefits and Trade-Offs of Aftermarket Options Aftermarket parts can come with real advantages, including a wider selection and sometimes a lower upfront cost compared to going through the dealership. Some aftermarket manufacturers even offer performance-oriented parts that aren't available as OEM equipment at all. The trade-off is that quality and warranty coverage vary from one aftermarket brand to the next, and a part that doesn't fit quite right can end up costing more in the long run if it needs to be replaced again sooner than expected. Comparing OEM and Aftermarket: Quality, Warranty, and Long-Term Value Every repair decision comes down to balancing fit, protection, and how long you expect the part to perform. Below is a side-by-side comparison of how OEM and aftermarket parts generally stack up. Factor OEM Parts Aftermarket Parts Fit/Tolerance Matches original vehicle specs precisely Designed to be similar, but measurements can vary Materials/Certification Built to manufacturer standards Varies by brand, some carry CAPA certification Warranty Coverage Toyota: 12 months parts-only over the counter, or 12 months parts and labor when dealer-installed. Mopar: 24 months/unlimited miles, parts and labor when dealer-installed. Performance Parts differ by part number Varies widely by manufacturer, often limited or none Typical Use Case Safety systems, warranty-covered repairs, precise-fit components Cosmetic parts, routine maintenance items Installation Considerations Straightforward fit reduces installation issues May require adjustment depending on brand quality Fit, Performance, and Compatibility Fit is where the OEM versus aftermarket conversation gets the most practical. Because OEM parts are built to match the original vehicle, they generally install without surprises. Aftermarket parts can perform just as well in many cases, but compatibility isn't a given across every brand, which is why checking specifications before buying matters, especially for parts tied to safety systems. Toyota and Mopar Warranty Terms Warranty terms differ significantly by brand and part type, and it's worth understanding each on its own rather than assuming one beats the other. Toyota Genuine Parts bought over the counter carry a 12-month parts-only warranty from the purchase date, with labor not covered. Buy the same part and have a Toyota dealer install it, and the 12-month coverage includes both parts and labor. Toyota's Accessory Warranty runs 36 months or 36,000 miles when the accessory is purchased alongside a new vehicle, or 12 months if purchased afterward. Mopar's Basic Limited Warranty covers most parts for 24 months with unlimited miles: parts and labor when an authorized dealership installs them, parts exchange only if you buy over the counter and install them yourself. Buy the part and have an independent shop install it and you keep the 24-month parts coverage plus up to $150 toward labor. Remanufactured and new powertrain components carry a separate 3-year/100,000-mile warranty that transfers to a subsequent owner, which is unusual since most parts warranties end when the vehicle changes hands. Performance Parts vary by prefix: 770 parts get the standard 24 months, PW parts run 12 months or 12,000 miles, and parts beginning with P or 0 are sold as-is with no coverage at all. Aftermarket warranty terms are set entirely by the manufacturer. Some brands back their products generously; others offer barely anything. Normal wear and tear, cosmetic issues, and improper installation aren't covered regardless of which type of part you use. Your Rights Under the Magnuson-Moss Warranty Act The Magnuson-Moss Warranty Act, enforced by the FTC, prevents manufacturers from voiding your vehicle's warranty just because you used an aftermarket part. The manufacturer would have to prove that specific part actually caused the problem. The Act also protects your right to have routine maintenance, like oil changes, brake pads, and belts, done at any shop you choose. In other words, choosing an aftermarket part on a vehicle still under warranty is your call, not a rule violation. Just keep your receipts and service records in case a claim comes up later. Long-Term Ownership and Resale Value Precise fit and factory-backed reliability tend to matter more the longer you plan to keep a vehicle. OEM parts help preserve the mechanical consistency a car was built with, which can matter to future buyers or appraisers down the road. Reputable aftermarket brands can hold up well too, but quality swings more across that space, and outcomes are less predictable than with OEM components. Choosing the Right Parts for Your Vehicle and Budget The right choice depends on what you're replacing and what you're trying to protect, whether that's your budget, your warranty, or your peace of mind on long drives along the Oregon Coast. When Genuine OEM Parts Make the Most Sense Safety-related components, warranty-covered repairs, and parts requiring precise fitment are where OEM parts earn their reputation. Brakes, airbags, and sensors are worth paying for the confidence that comes with a part engineered to match the vehicle exactly. When Aftermarket Parts May Be a Reasonable Choice Cosmetic components and routine maintenance items are often reasonable candidates for aftermarket parts, especially when budget is a bigger concern than exact factory specs. Before buying aftermarket, it helps to run through a short checklist. Is this part covered by my vehicle's warranty right now. Is this a safety-related component like brakes, steering, or airbags. Does it carry CAPA certification for fit and performance. Will installation require special tools or dealership-level expertise. CAPA, the Certified Automotive Parts Association, has independently tested aftermarket collision parts like bumpers, fenders, and headlights since 1987, checking them against OEM standards for fit and function. CAPA sets benchmarks for the metals, plastics, lighting components, foam, and bumpers used in these parts, giving shoppers a way to gauge aftermarket quality beyond guesswork.

Picking the right bed cover isn't just about looks. It changes how your cargo stays loaded and dry, and how much protection you get against theft. If you're comparing types of truck bed covers for a truck you already own, or you're still shopping for the right truck, this guide breaks down how each style works and which one fits your daily routine. Why Truck Bed Covers Matter for Oregon Coast Drivers Around Warrenton, OR, rainfall isn't a seasonal inconvenience, it's a year-round reality. The Astoria/Warrenton area sees a normal annual rainfall of 70.26 inches, with November alone averaging 11.05 inches (NWS). A bed cover keeps your cargo dry through that, cuts down on UV fading for your bed liner, and keeps tools or gear tucked out of sight when you're parked at a trailhead or job site. Soft Tonneau Covers: Roll-Up and Folding Styles Soft bed covers are built from vinyl or canvas material stretched over a frame. They're the lightest, most affordable category, and most owners can install one without drilling into the bed. How Roll-Up Covers Work and Who They Suit A roll-up soft cover uses vinyl or canvas stretched over a bow frame. You unsnap it and roll it toward the cab, opening the entire bed in seconds. Installation typically takes under 30 minutes with no drilling required. This style suits drivers who need frequent full-bed access, like weekend haulers moving mulch or furniture. How Folding (Tri-Fold) Covers Work and Who They Suit Tri-fold covers use marine-grade vinyl stretched over a rigid aluminum frame, split into three hinged panels. You fold the rearmost panel toward the middle, then toward the cab, giving you a choice between partial or full bed access. This works well for drivers who split time between work errands and weekend trips, since you can leave part of the bed covered while loading taller items in front. Soft Cover Pros, Cons, and Weather Considerations Soft covers keep out light rain but aren't sealed tight, so standing water or a heavy downpour can find its way in around the edges. Security-wise, they offer essentially zero theft deterrence; a pocket knife can slice through the vinyl in seconds. Their advantage is weight: soft covers come off easily when you need the whole bed open, and installation rarely takes more than an hour. Hard Tonneau Covers: Roll-Up, Folding, and One-Piece Styles Hard covers come in three main configurations: hard roll-up, hard folding, and one-piece hinged. All three trade some of the soft cover's flexibility for meaningfully better security and weather sealing. Hard Roll-Up and Hard Folding Covers Hard roll-up covers use interlocking aluminum, polycarbonate, or composite slats, which add real reinforcement compared to a soft shell alone. Hard folding covers mount rigid panels on an aluminum frame, using a hidden or quick-release latch that auto-locks each panel. Many models include weather sealing features such as perimeter bulb seals and internal drain tubes that channel water out behind the wheel wells. Some hard roll-up and folding covers can be driven with the cover open, partially open, or fully closed, offering more flexibility than a one-piece design. One-Piece Hinged Hard Covers A one-piece hard cover lifts from the tailgate end like a hood, using a single solid panel. It's the most rigid and secure configuration, which is why work trucks and fleet vehicles commonly pair it with a spray-on bedliner. The tradeoff is flexibility: cargo taller than the closed cover simply won't fit, so this style suits drivers hauling consistent, lower-profile loads. Hard Cover Pros, Cons, and Security Benefits Hard covers overall provide strong locking mechanisms and good weather sealing. Per LINE-X's own comparison guide, hard folding, retractable, one-piece, and topper-style covers rank among the best options for security. Brand-specific weight ratings back up that durability angle: BAKFlip lists its BAKFlip G2 at 300 lbs of evenly distributed support and the BAKFlip MX4 at 400 lbs. The downside is weight and bulk, which can make removal a two-person job compared with a soft cover. Retractable and Snap-On Cover Options Not every driver wants a fixed roll-up or hinged panel. Retractable and snap-on styles fill the gap between full security and everyday convenience. Retractable Covers for Flexible Access Retractable covers use interlocking aluminum or polycarbonate slats that retract into a canister mounted at the front of the bed, operated with a simple handle pull. What you end up with is a flush, locked appearance with full bed access whenever it's open. Retrax backs its RetraxPRO MX and XR models with its Legendary Lifetime Warranty, while RetraxONE models carry a limited lifetime warranty with replacement costs prorated after the first year. Its aluminum-slat covers support up to 500 lbs of evenly distributed weight and are tested from -40°F to 180°F and up to 95 percent humidity. Installation runs about 2 to 3 hours, longer for electric-powered versions that need power routing. If you're unsure about fitment or wiring, our service team can walk through installation details before you buy. Snap-On and Low-Profile Vinyl Covers for Budget Buyers Snap-on vinyl covers mount on a frame clamped to the bed rails and secure with snaps, with individual sections that unsnap for quick access. Per LINE-X's comparison, this style stays visible above the bed rails rather than sitting flush, so it won't have the low-profile look of retractable or hard one-piece designs. It's a reasonable entry point if a simple, budget-friendly setup matters more than a polished finish. Soft vs Hard Tonneau Cover: Side-by-Side Comparison Here's a quick comparison to help narrow down which type of cover is best for your situation. Cover Style Best For Relative Cost Bed Access Weather Sealing Look Soft roll-up Frequent full-bed loading $ Full, rolls to cab Water-resistant Sits above bed rails Soft tri-fold Mixed work and weekend use $ Partial or full Water-resistant Low, slight rail profile Snap-on vinyl Budget basic coverage $ Section by section Water-resistant Sits above bed rails Hard roll-up Security with full access $$ Full, rolls to cab Good, often with seals and drains Low profile Hard folding All-around daily driver pick $$ Partial or full Good, often with seals and drains Flush, low profile Retractable Flexible access, premium finish $$$ Any position, locks open Good, sealed canister and drains Flush, cleanest look One-piece hinged Work trucks, consistent low loads $$$ Full, but limits cargo height Best sealing Flush, matches paint Matching a Cover to How You Actually Use Your Truck Which cover is best really depends on how you use your truck week to week, not just which one looks best in the driveway. Matching Cover Type to Bed Access Needs If you're constantly loading bulky items, a roll-up or folding cover keeps that flexibility intact. If security matters more than access, a hard folding or one-piece design makes more sense. Weather Protection and Cargo Security on the Oregon Coast Given the rainfall totals mentioned earlier, hard one-piece and retractable covers come closest to sealing out water, though no cover on the market is truly waterproof. For drivers navigating gravel or rural roads in Clatsop County or Pacific County, that sealing difference matters more over time, especially if you're storing gear between trips rather than unloading daily. How you use the bed matters just as much. If your truck works during the week, think about what else lives back there: a crossbed toolbox, ladder rack, or bed rails all affect which covers fit, and some styles won't clear a toolbox at all. If your weekends involve crab rings, waders, camping gear, or kayak paddles, a locking cover means you can leave gear in the bed at a trailhead or boat ramp instead of hauling it into the cab. Tall or awkward loads, like a cooler stack or a rolled tent, favor a folding or retractable cover you can open partway, while a one-piece cover caps how tall your cargo can be. Looks and Getting It Installed Appearance splits the categories fairly cleanly. Soft roll-up and snap-on covers sit above the bed rails, so the cover reads as an add-on. Hard folding, retractable, and one-piece covers mount flush or near-flush for a factory look, and one-piece covers can often be color-matched to your truck's paint. Soft covers remain the quicker path to basic protection, while hard and retractable covers ask for a bigger investment in exchange for security and a cleaner look. Fitment is vehicle-specific by year, make, model, and bed length, so covers aren't universal across every model year, even within the same brand. Always confirm fitment before buying. Frequently Asked Questions About Truck Bed Covers Are Tonneau Covers Waterproof? No cover on the market is fully waterproof. All tonneau covers are water-resistant to varying degrees, and hard one-piece and retractable styles come closest to sealing out water completely. Do Tonneau Covers Affect Fuel Economy? Results vary by cover type, speed, and load, so there's no universal mpg gain to expect. A SEMA wind-tunnel study tested 13 covers and found about a 5 percent drag reduction, which translated to an estimated 2 percent fuel economy improvement at an average 48 mph. Consumer Reports found the opposite in a road test: a V8 Ram returned 22.3 mpg at highway speed with the tailgate up and no cover, dropping to 21.4 mpg with a soft tonneau installed, about a 4 percent loss. Treat any fuel economy claim as a secondary benefit, not a guarantee. Can I Install a Tonneau Cover Myself? Soft roll-up and tri-fold covers are generally the easiest to install, often installable in 20 to 45 minutes without drilling. Hard folding covers take closer to 1 to 2 hours, and retractable covers, especially electric versions, can run 2 to 3 hours with additional wiring work.
