ROUSH has worked in conjunction with Fox Shocks to develop the ultimate off-road 2017-2018 Raptor suspension, with a greater body diameter, more oil capacity, more valving for range-specific tuning, and increased thermal cycling capacity, with finned reservoirs and unmatched technology. Designed for the asphalt and the mud, this suspension system offers a no-compromise solution that provides full range control through external valve adjustments (high and low speeds). Sporting an anodized body finish, the teams at ROUSH and Fox developed and tested this system, achieving full FMVSS testing passing scores for both ABS and emergency handling when paired with our 20-inch wheel and BFG AT KO2 combination.
