Upgrade your Chevrolet 1500 with the FOX 2.5 Performance Elite DSC coilover kits for improved performance and style. These coil-overs allow for maximum wheel travel and are compatible with aftermarket upper arms. The 2.5" shock body provides added oil capacity for aggressive use. The shocks are fully rebuildable and revalveable for tuning and maintenance. The remote external reservoirs increase oil capacity for lower operating temperatures. The Dual Speed Compression (DSC) adjuster allows for precise tuning with twelve low-speed and ten high-speed compression levels. The integrated coil spring can be adjusted for preload and ride height. Our upper arms address limitations of stock arms, increasing wheel travel and strength. They also improve vehicle alignment and handling on and off-road. In the rear, we recommend the FOX 2.5 Performance Elite DSC Series shocks for increased damping and control. Please note compatibility with electronic adaptive ride control suspension systems and potential clearance issues with factory wheels. We recommend aftermarket wheels with a zero offset for optimal performance and fit.
