3.5-Inch Lift Kit with ADX Shocks, GM HD Cast Steel Suspension

3.5-Inch Lift Kit with ADX Shocks, GM HD Cast Steel Suspension, fitment-checked

Suspension material is the qualifier here: Skyjacker lists this kit for cast steel, where the closely numbered alternative covers the aluminum and stamped variants. Both give 3.5 in. with ADX 2.0 remote reservoir shocks on the 2014-2016 GM heavy duty trucks.

GM built these trucks with more than one front suspension material, and the lift kit has to match. This is the cast steel listing. Everything else follows the same recipe: 3.5 in. of lift, ADX 2.0 shocks with remote reservoirs so the damping holds up under sustained load, covering the 2014-2016 Silverado 2500 HD and 3500 HD and the GMC Sierra 3500 HD. Boxed weight is 65.1 lb. Identify what your front suspension is made of before ordering. The fitment tables are otherwise identical.
