Transform your 4th Generation 4Runner into a high-clearance off-road machine with Advanced Fiberglass Concepts 2003-2009 Toyota 4Runner Fenders. These fenders are specifically engineered for the 4th Gen platform, offering the ultimate combination of aggressive wide-body styling and increased wheel well clearance.

Maximum Clearance for Technical Terrain
With a significant 4.5" flare and 2" rise, these fenders provide enough room to run larger tires and high-travel suspension systems without the risk of rubbing against the body panels. This added width is crucial for maintaining a stable footprint on technical trails while protecting your vehicle’s sides from tire spray and trail debris. Like all ADV products, these are hand-laid in the USA using a proprietary resin blend for maximum durability and flexibility.

Installation & Fitment

These fenders are designed as a bolt-on replacement for your factory steel panels. While they use most factory mounting locations, some drilling is required to ensure perfect alignment. Because fiberglass is thicker than factory steel, you should expect to spend time on minor sanding and gap adjustments to achieve a factory-level fit. For the best results, professional installation by an experienced shop is recommended.
