Quick Front End Lift for GMC AT4 Off-Road Trucks
The Skyjacker C205KE torsion key leveling kit gives 2020-2024 GMC Sierra 2500HD AT4 owners a straightforward way to level the front end and add clearance for larger tires. The C205KE replaces the factory torsion keys with a re indexed key that raises front ride height by roughly 2 inches, correcting the factory rake that leaves many HD trucks sitting lower in front than in the rear.
Because the C205KE works through the factory torsion bar system, installation does not require cutting or drilling on most applications. A torsion bar tool is needed to safely unload and reinstall the bars, and a professional alignment is required afterward to bring the truck back to factory specifications. The C205KE is a popular first step for AT4 owners planning to add a leveling kit before larger off road tires and wheels.
