The Camburg FOX 2.0 Trail Series kit is a suspension system for the Ford F-150 4WD. It includes FOX 2.0 Performance Series IFP Coilovers for 0-2 inches of lift and increased wheel travel. The shocks have a smooth-bore, clear coated, zinc plated, honed seamless alloy body, black anodized 6061-T6 billet aluminum components, and a 5/8" hard chrome plated heat treated alloy steel shaft. They also have an internal reservoir design to separate shock oil from high-pressure nitrogen. The kit also includes uniball upper arms that replace the stock ball-joint for increased wheel travel and improved performance. The arms have more caster and a changed camber curve for correct alignment and better driving characteristics. In the rear, the kit includes FOX 2.0 Performance Series shocks with a larger aluminum shock body for better offroad performance. Note that factory 20" wheels may not clear the upper arm and may require a wheel spacer. Aftermarket wheels with the correct offset are recommended for optimum performance and fit. The kit provides improved ride and handling, easy bolt-on installation, and is made in the USA.
