About this part

3-3.5 Inch Component Box with Upper Control Arms, GM HD, fitment-checked

The component box behind Skyjacker's 3-3.5 in. GM heavy duty kits: front upper control arms, torsion key, differential lowering spacers, shock extension brackets and rear hardware, without the shocks the complete kits bundle.

Where the complete kits in this range come with a damper choice, this box supplies the structure and leaves the shocks to you: front upper control arms, a torsion key, differential lowering spacers, shock extension brackets and rear lift hardware. That suits a build where the shocks are already sorted or being sourced elsewhere. Lift is 3-3.5 in. on the 2020-2023 Silverado 2500 HD and 3500 HD and the GMC Sierra equivalents. 60.3 lb boxed.
