Show original supplier description
The RTR Side Rocker Splitters are designed to enhance the exterior aesthetics of your 2015-2017 Ford Mustang with a modern, aggressive, race-inspired appearance. Developed in conjunction with Vaughn Gittin Jr. and featured as original equipment on the Ford Mustang RTR, these splitters are a direct upgrade for your vehicle. Constructed from OEM-quality, high-pressure injection-molded TPO (thermal plastic olefin), these rocker splitters are built for durability and longevity. The grained texture not only contributes to an OEM look but also helps resist damage from road debris. Installation is straightforward, utilizing the stock hardware and provided 3M double-sided automotive bonding tape for a secure fit. These splitters are specifically designed to fit all 2015 to 2017 Ford Mustangs, including V6, EcoBoost, GT, and Shelby GT350 models. The package includes both driver and passenger side components, along with rear extensions for a complete rocker panel transformation. Please note that these splitters are not compatible with most winglets, nor will they fit with CDC Outlaw Rocker side skirts.
