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

Built for Chevy and GMC 2500HD/3500HD owners who demand aggressive ground clearance without sacrificing factory ride quality — this 7.5" Vertex lift kit delivers the bold stance and off-road capability your truck deserves while preserving every factory advantage. Engineered with a Non-Torsion Drop design, it supports tire sizes up to 40.0" and maintains proper axle geometry, torsion bar placement, and stock track width, so your truck handles as confidently lifted as it does stock.

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 crossmember, laser-cut and Hammer Black finished for durability and clean looks.
• NTD Bracket Box — 1/2" thick brackets engineered for the Non-Torsion Drop layout, eliminating the need for differential drilling or cutting.
• 5-7in Kit Box — mid-range suspension components that bridge your factory setup to full lift height.
• 7in RR Kit Box — rear lift components delivering the full 7.5" height and improved ground clearance.
• Dr Knuckle & Pass Knuckle — driver and passenger-side knuckles that maintain factory axle angles and prevent premature wear.
• 253x Kit Box — additional structural reinforcement for the Chevy/GMC platform.
• Vertex 2.5 FR Shock (pair) — nitrogen-charged front shocks tuned for 5.0"–7.5" lift, preserving factory ride comfort.
• Vertex 2.5 RR Shock (pair) — rear shocks scaled for 3.5"–7.5" travel, balancing aggressive stance with smooth handling.

Important notes

• Does NOT fit dually models due to u-bolt design variances.
• Does NOT work with factory wheels. Chevy/GMC trucks 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.
• Models equipped with factory rear overload springs require the longer u-bolt kit (SKU 7664) — confirm your spring type before ordering.
• Minor cutting and drilling required during installation. A torsion bar removal tool (SKU 1067) is recommended for ease of install.
