Built for GMC Sierra 1500 owners who want more ground clearance without going full-size, this 3.5-inch lift kit levels your ride and opens up tire options up to 35 inches. It combines forged aluminum upper control arms with M1 struts to preserve factory suspension geometry while delivering the aggressive stance and off-road capability you're after.

What's included

Important notes

- Does NOT fit AT4 or AT4X models — both are equipped with a factory 2-inch lift. AT4X also features Multimatic DSSV dampers.
- Does NOT work on diesel models due to variances in motor weight that affect strut geometry.
- Recommended tire range: 33–35 inches. Tire clearance tested and validated within this window.
