Our Camburg FOX 2.0 Trail Series kit is a suspension system for Toyota 4-Runner. 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 upper arms to address limitations of stock arms, with options for tubular uniball or tubular X-joint arms. These arms increase wheel travel, improve strength, and correct geometry for better alignment and handling. In the rear, the kit includes FOX 2.0 Performance Series shocks with a larger aluminum shock body for better performance offroad. For X-Reas equipped models, the short hydraulic hoses connecting to the OEM shocks need to be removed and drained.
