2019-23 4WD Chevy Silverado, GMC Sierra 1500 3.5" UCA lift kit, Nitro shocks

Up the game on your Silverado or Sierra 1500 with the Zone Offroad 3.5” Adventure Series upper control arm lift kit. This lift kit takes advantage of the factory suspension mounting points to improve performance and capability as well as clearance for larger tires. The high strength replacement upper control arms are boxed and fully welded including a specially designed indexed ball joint cup that repositions the ball joints back to the neutral position. This design provides increased suspension travel, improved strength and durability. The grease fitting is located under the ball joint dust cap for easy maintenance.

A 2-piece strut spacer provides a full 3.5” of front lift that will not overextend the suspension at full droop. This combination of a top mount and preload spacer will correctly position the strut assembly to maintain proper clearance with the CV axles under all driving conditions. Optional wheel spacers and weld-in steering stops are included to allow for a wider range of wheel and tire combinations. The rear is lifted using a 2” rear block kit. Rear Nitro shocks complete this package to give your Silverado or Sierra a level and more aggressive stance.
