7 Inch Lift Kit | Ntd | M1 | W/ Overloads | Chevy/gmc 2500hd/3500hd (20-26)

Built for Chevy and GMC 2500HD/3500HD owners who want serious ground clearance without sacrificing factory ride quality, this 7-inch non-torsion drop lift kit delivers the height you need to run 37–40 inch tires while keeping your suspension geometry true to spec. The clean, laser-cut design maintains an integrated, factory-style appearance underneath — no exposed torsion bars — and preserves OEM track width for predictable handling and tire wear.

What's included

• 7" NTD Bracket Box — laser-cut front brackets engineered for precise, bolt-on fitment with a factory-style appearance and RC logo.
• Lifted Knuckles (Driver & Passenger) — maintain axle geometry and angle at factory spec, reducing wear and stress on drivetrain components.
• Crossmember Box — heavy-duty steel crossmember provides structural support and integration with the overall suspension system.
• 7" NTD Rear Kit with Overloads — rear suspension lift paired with overload springs to handle load and maintain ride quality.
• Differential Skid Plate — protects the differential during off-road adventures without requiring any drilling or modification.
• M1 Monotube Shock Pairs — nitrogen-charged shocks tuned to complement the lift geometry and preserve factory ride comfort and control.

Important notes

• This kit does NOT fit dually models — single-rear-wheel trucks only.
• ONLY fits models equipped with rear overload springs. Does not fit AT4X or ZR2 models, which come factory-equipped with 1.5-inch lift and Multimatic DSSV dampers.
• Does not work with factory OEM wheels; aftermarket wheels with proper backspacing are required for tire fitment in the 37–40 inch range.
• Gas models may require exhaust modification for driveshaft clearance. Diesel models do not have this requirement.
• No drivetrain modifications, differential drilling, or additional upgrades needed — bolt-on design keeps axles true to factory spec.

Why customers pick this at Road Runner

• Non-torsion drop design keeps suspension tucked and streamlined for a clean, factory-integrated appearance — no exposed bars.
• Preserved OEM geometry means corrected caster and camber out of the box; alignment performed in-house as part of every lift install.
• Rough Country lifetime warranty backed locally by certified technicians who install these kits every week.
• Bolt-on fitment with laser-cut components — no cutting, drilling, or custom fabrication required.
• Factory ride quality retained; no harsh changes to comfort or handling despite the 7-inch gain in height.
