Specially designed for the 2019-2023 Chevy ZR2 and GMC 1500 AT4X trucks, these kits are designed to a higher standard, working within the parameters of the factory suspension and steering geometry to maximize potential while allowing optimal clearance for larger tires. Kits include strut spacers, adventure series upper control arms, hardware packs and steering stop extensions.

Complete 1.75" leveling recommended for AT4X, Trail Boss suspension not as raked for the factory so installing without thin preload spacer will net 1-3/8" lift for a level stance. Tires wider than 295/ cannot be installed on factory wheels due to clearance issues to the steering knuckles. Will not fit Adaptive Ride Control (ARC) equipped models. 2022 Models: This system has not been tested on models equipped with Super Cruise.
