Introducing FOX's Performance Series 2.0 S/R coilovers, a budget-friendly kit for lifting trucks and venturing into off-roading. These coilovers offer superior performance and durability. The shock features a custom-molded spring seat, allowing reuse of stock springs and mounting hardware. Its lightweight, rust-resistant aluminum body houses an internal nitrogen-charged gas reservoir, separated from the shock oil by an internal floating piston (IFP). With three preload settings, you can choose between 0", 1", or 2" of lift. Our uniball upper arms replace stock arms, increasing wheel travel, strength, and longevity. They also improve alignment, driving characteristics, and handling. In the rear, FOX's Performance Series 2.0 IFP shocks provide better off-road performance, increased wheel travel, and controlled ride. You can opt to exclude them initially and add them later. Note that some factory wheels may require a spacer to clear the upper arm. We recommend aftermarket wheels with zero offset for optimal performance and fit. Springs and spring mounting hardware are not included; a spring compressor is required for installation.
