5 Inch Lift Kit | Torsion Drop | M1 | Chevy/gmc 2500hd/3500hd (20-26)

Built for Chevy and GMC 2500HD/3500HD owners who want a level stance with aggressive ground clearance, this 5-inch Rough Country lift kit delivers the torsion-drop look without sacrificing ride quality or driveline geometry. It maintains factory track width and axle angle while clearing 33–35 inch tires with confidence.

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

What's included

• Driver Knuckle — precision-engineered replacement for proper suspension geometry and steering response.

• 5 inch Torsion Bar Drop Kit Box (qty 2) — specially designed brackets maintain factory torsion-bar geometry while achieving the desired lift height.
