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

Built for Chevy and GMC 2500HD/3500HD owners who want serious lift without sacrificing ride quality — this 7.5" suspension lift kit combines aggressive ground clearance with factory-like handling. The Torsion Drop design preserves your truck's geometry and lets you fit 37"–40" tires while keeping the stock track width and driveline angles intact.

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 crossmembers, laser-cut and powder-coated in Hammer Black to match factory finishes.
• 5–7" Kit Box — Core lift components engineered for your 2500HD/3500HD platform.
• 7" Torsion Bar Drop Kit Box — Torsion drop brackets that improve ride quality and handling while preserving factory angles.
• Driver & Passenger Knuckles — Precision-fitted front knuckles that maintain factory geometry and drivetrain alignment.
• 253x Kit Box — Suspension geometry correction kit to keep caster and camber proper after the lift.
• Vertex 2.5 Front Shocks (pair) — Premium reservoir shocks tuned for 5–7" lift heights, delivering smooth, controlled articulation.
• Vertex 2.5 Rear Shocks (pair) — Reservoir-style rear shocks engineered for 3.5–7.5" lift, balancing comfort and capability.

Important notes

• Factory rear overload springs must be removed on equipped models.
• This kit does NOT fit dually models due to u-bolt design variances.
• Does NOT work with factory wheels. Models equipped with factory 17-inch wheels must use 17-inch or larger aftermarket wheels due to larger calipers and rotors.
• Gas models may require exhaust modification for driveshaft clearance.
• Requires minor cutting and drilling. A torsion bar removal tool (Rough Country #1067) is recommended for ease of installation.
