What's included
- Strut Kit Box — contains the complete front strut assembly and mounting hardware for your Sierra 1500.
- Forged Upper Control Arms — engineered aluminum arms that correct suspension geometry at 3.5 inches of lift, maintaining proper caster and ride quality.
- M1 Loaded Strut Pair — pre-assembled nitrogen-charged front struts tuned for 3.5-inch lift height, ready to bolt in.
- M1 Monotube Shock Pair — rear shocks matched to the 2.5-inch rear lift height for balanced suspension response.
Important notes
- Does NOT fit Denali or Denali Ultimate models — these are equipped with Adaptive Ride Control and are incompatible with this kit.
- Does NOT fit AT4 or AT4X models — both come factory with a 2-inch lift and either standard or Multimatic DSSV dampers that conflict with this suspension setup.
- Does NOT fit diesel-powered models — motor weight variances prevent Rough Country strut options from fitting safely in diesel engines.
- Installation requires a strut compressor and cutting/drilling of factory mounting points.
- Recommended tire range: 33–35 inches; exceeding 35 inches may contact suspension components or fender liners.
