7.5 Inch Lift Kit | Ntd | Chevy/gmc 2500hd/3500hd (11-19)

Built for Chevy and GMC 2500HD/3500HD owners who want a commanding stance without sacrificing factory ride quality, this 7.5-inch suspension lift kit delivers aggressive ground clearance while preserving your truck's factory angles, axle geometry, and torsion bar placement. Supports tire sizes from 37.0" to 40.0" and installs without drilling the differential or modifying your drivetrain or exhaust.

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

• Crossmember Box — Heavy-duty 1/4" thick steel component that reinforces the frame structure and distributes suspension loads evenly.
• 5–7 in Kit Box — Primary lift components that raise your truck to the specified height while maintaining factory geometry.
• Driver and Passenger Knuckles — Precision-engineered steering knuckles that preserve proper caster and keep wheels aligned without additional modifications.
• 7 in RR Kit Box — Rear suspension lift assembly engineered for the Non-Torsion Drop layout.
• NTD Bracket Box — Heavy-duty 1/2" thick brackets (laser-cut and finished in Hammer Black) that anchor the lift without requiring differential drilling.
• N3 Shock Pair (Qty 2) — Nitrogen-charged shocks tuned to retain smooth, factory-like ride quality; upgradeable to M1, V2 monotubes, or Vertex reservoir shocks.

Important notes

• Does NOT fit dually models due to u-bolt design variances.
• Does NOT work with factory wheels. If your truck has factory 17-inch wheels, you must use 17-inch or larger aftermarket wheels due to larger calipers and rotors.
• Gas models may require minor exhaust modification for driveshaft clearance.
• Models equipped with factory rear overload springs require a longer u-bolt kit (SKU 7664) — confirm your truck's spring setup before ordering.
• Requires minor cutting and drilling during installation; a torsion bar removal tool (SKU 1067) is recommended for ease of install.
