ReadyLIFT 1.75 Inch Leveling Kit - 2019-2026 Silverado Trail Boss and Sierra AT4 4WD (66-3921)

This ReadyLIFT kit is a 1.75 inch front leveling kit for the 2019-2026 Chevy Silverado 1500 Trail Boss and GMC Sierra 1500 AT4. It is built to avoid the ball joint binding and strut-to-CV axle contact that a traditional leveling kit can cause on the factory 2 inch lifted AT4 and Trail Boss front end. The kit combines tubular steel upper control arms with CNC-machined billet aluminum strut spacers.
