3 Inch Lift Kit | Ucas | M1 | Chevy/gmc 2500hd/3500hd (20-26)

Built for Chevy and GMC 2500HD/3500HD owners who want aggressive stance and tire clearance without compromising driveline geometry, this 3-inch bolt-on lift kit delivers exactly that. Rough Country engineered it with forged upper control arms, differential drop brackets, and a fully reversible design — no cutting, no drilling, no special tools. You'll run 33"–34" tires confidently while keeping your factory frame intact.
