Icon Direct RV Fender Flares: Top Overall Pick
Protect your RV with this durable, black ABS tandem axle fender skirt. Measuring 69 3/8" x 9 1/2", it features a scuff-resistant texture and fits popular brands like Crossroads, Keystone, and Forest River.
When you are looking for a direct replacement that feels like it rolled off the factory line, Icon Direct is the industry gold standard. They maintain an extensive library of molds, meaning they likely have the exact shape needed for your specific RV make and model.
These flares are crafted from high-impact ABS plastic, providing a rigid yet flexible barrier against the elements. If you want a "set it and forget it" solution that requires minimal modification during the install, this is your best bet. It is the perfect choice for the owner who values OEM-level precision without the dealership markup.
RecPro Universal RV Fenders: Best Custom Fit
Universal fitment is often a gamble, but RecPro has refined the process for those of us working with older rigs or custom conversions. These fenders are designed with a degree of malleability that allows you to trim and shape them to fit non-standard wheel well openings.
They are ideal for the DIY enthusiast who isn’t afraid to break out the jigsaw and fine-tune the mounting points. While they require more labor than a molded replacement, the trade-off is a tailored look that can be adapted to almost any chassis. If your RV is a "one-of-a-kind" build, RecPro gives you the control you need to ensure a tight, professional seal.
Lippert Components Fenders: Best OEM Quality
Protect your RV's slide-out components with the Lippert Flex Guard. This kit prevents sagging and damage with a flexible design, and it includes all necessary mounting hardware for easy installation.
Lippert is a massive name in the RV supply chain, and for good reason—they manufacture the original components for a significant percentage of modern trailers. Choosing their fenders means you are getting the exact same material specifications and mounting hardware that the manufacturer installed at the factory.
This is the safest route for someone who wants to maintain the resale value of their rig by keeping it as close to original as possible. You won’t have to worry about weird gaps or mismatched bolt patterns. If you prefer reliability and standard-issue compatibility over customization, Lippert is the clear, logical choice.
Dura-Shield Fender Guards: Best for Durability
If your lifestyle involves frequent travel on gravel roads, forest service trails, or harsh winter climates, standard plastic might not cut it. Dura-Shield specializes in reinforced materials designed to withstand impacts that would shatter thinner, cheaper alternatives.
These guards are thicker and more resilient, making them a smart investment for full-time nomads who put serious mileage on their rigs. While they might be slightly heavier, the trade-off is a significant reduction in the risk of cracking from road salt or flying stones. These are for the traveler who prioritizes longevity over weight savings.
JR Products Fender Skirts: Best Value Option
JR Products is the go-to brand when you need a functional, cost-effective fix without breaking the bank. They offer a wide range of standard sizes that cover the most common trailer configurations found on the road today.
They aren’t necessarily the most heavy-duty option on the market, but they are perfectly adequate for weekend warriors and seasonal campers. If you are prepping a rig for sale or simply need to patch up a damaged section on a budget, JR Products offers the best return on investment. They get the job done cleanly and efficiently.
Diamond Group ABS Fenders: Best Lightweight Fix
Weight is the constant enemy of the small-living advocate, especially if you are towing with a smaller vehicle. Diamond Group’s ABS fenders are remarkably lightweight, ensuring you don’t add unnecessary strain to your suspension or fuel economy.
Despite their low weight, they offer excellent UV resistance, which is critical for preventing the brittle cracking that plagues older rigs. These are an excellent choice for teardrop trailers, pop-ups, or any lightweight build where every pound counts. They are simple, effective, and won’t weigh your project down.
Essential Tools for Fender Installation
A successful install is 90% preparation and 10% execution. You will need a reliable cordless drill, a set of high-quality drill bits, and a jigsaw with a fine-tooth blade for any necessary trimming.
Don’t forget to stock up on stainless steel screws and rubber-backed washers to prevent rust and provide a watertight seal. Having a second pair of hands is also invaluable; holding a fender in place while trying to align screw holes is a recipe for frustration. Keep these tools organized, and the job will be significantly smoother.
Measuring Your RV Wheel Well Dimensions
Never rely on guesswork or generic measurements when ordering replacements. Use a flexible measuring tape to map out the arch of your wheel well, noting both the width at the base and the total height from the bottom edge to the peak.
Take photos of your existing fenders from multiple angles, as subtle curves and mounting lips can vary wildly between model years. I always recommend measuring twice and checking the manufacturer’s technical diagrams before hitting the "order" button. Precision at this stage prevents the headache of a return shipping process.
Applying Sealants for Weatherproofing
Installing a fender is only half the battle; keeping the elements out of your sidewalls is the other. Always apply a high-quality, RV-specific lap sealant or butyl tape behind the mounting flange before you drive the first screw.
This creates a gasket-like barrier that prevents water from seeping into the screw holes and rotting your subfloor or wall structure. Avoid using household silicone, as it rarely adheres well to the textured surfaces of an RV sidewall. A proper bead of sealant ensures your hard work lasts for years rather than months.
Maintaining Your RV Fender Exterior Finishes
Fender flares take the brunt of road grime, which can lead to oxidation and premature fading. A simple wash with mild soap and water after every long trip goes a long way in preserving the integrity of the plastic.
Consider applying a UV-protectant spray specifically formulated for plastics to keep them flexible and prevent the dreaded "chalking" effect. Regularly inspect the mounting screws for tightness, as road vibration can loosen them over time. A few minutes of preventative maintenance keeps your rig looking sharp and keeps your wheel wells protected from water damage.
Replacing your RV fender flares is a manageable project that pays dividends in both aesthetics and long-term structural health. By selecting the right material for your travel style and ensuring a watertight seal, you are proactively protecting your mobile home from the inevitable wear of the road. Take your measurements carefully, choose quality hardware, and you will have a rig that stays road-ready for many seasons to come.
