If you’re looking to enhance the functionality and aesthetics of your Jeep Wrangler (2018-2021) or Gladiator (2020-2021), the Fabtech K4187 inner fenders are a must-have upgrade. Designed specifically to replace the factory plastic liners, these inner fenders seamlessly integrate with Fabtech Tube Fenders, providing a complete fender upgrade that not only looks great but also performs exceptionally well.
Crafted from durable mill finish 6061 aluminum, these inner fenders cover the entire inner wheel well opening, effectively eliminating gaps that can allow mud and debris to infiltrate your engine bay. This design is crucial for off-road enthusiasts who tackle tough trails and need reliable protection for their Jeep’s vital components.
The K4187 inner fenders are engineered to provide ample clearance for larger tires, accommodating up to 37" tires with a 3" lift and 40" tires with a 5" lift. This means you can tackle any terrain without worrying about rubbing or clearance issues.
Jeep Gladiator owners have shared their experiences with the K4187 inner fenders, noting that the fitment is spot on and the installation process is straightforward. One customer mentioned, "I installed these on my 2021 Gladiator, and they not only look fantastic but also keep the mud out during off-road adventures. Plus, the venting helps keep my engine cool on those hot summer days." Another Jeep Wrangler owner remarked, "These fenders paired perfectly with my Fabtech Tube Fenders, giving my Jeep a more aggressive stance without any clearance issues, even with 37s!"
Whether you’re hitting the trails or just cruising around town, the Fabtech K4187 inner fenders are designed to elevate your Jeep’s performance and style. With their rugged construction and practical design, these fenders will not only protect your vehicle but also turn heads wherever you go.
