Specially designed for the 2019-2021 Chevy Trail Boss and GMC AT4 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. Due to limitations with the factory UCA that may cause premature wear these kits include high strength adventure series upper control arms to provide long life, additional travel and superior strength.
