3.5 Inch Lift Kit | Mono Leaf Rear | Vertex | Gmc Sierra 1500 2wd/4wd (25-26)

Built for GMC Sierra 1500 owners who want a balanced lift without going full-height, this 3.5-inch Suspension Lift Kit delivers a level stance, improved ground clearance, and the geometry preservation that keeps your truck riding right. The kit combines a 3.5-inch front lift with a 2.5-inch rear lift and forged aluminum upper control arms — engineered to maintain factory suspension angles so your ride stays smooth and predictable. You'll gain clearance for 33"–35" tires and an aggressive, proportioned look that works whether you're on pavement or trail.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.
