Built for GMC Sierra 1500 diesel owners who want commanding ground clearance without sacrificing ride quality, this 6-inch lift kit raises your truck from front to rear while preserving factory suspension geometry. You'll gain enough clearance to run 35" tires and achieve that aggressive stance GMC's fourth-generation design deserves.
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
- Universal Kit Box (2WD, 2025) — Foundation components for the 2025 Sierra 1500 platform.
- 6" Driver and Passenger Knuckle Boxes — Durable steel knuckles engineered to reduce control arm angles and simulate factory geometry.
- Diesel 6" Front Kit Box — Diesel-specific front suspension components optimized for engine weight distribution.
- 6" Front Kit Box — Additional front-end reinforcement and bracketing.
- 6" Crossmember Box — Drop crossmember design maintains ideal suspension geometry for superior handling and stability.
- N3 Shock Pair — Nitrogen-charged shocks deliver consistent dampening and ride quality throughout the lift height.
Important notes
- Does NOT fit Denali models — they are equipped with Adaptive Ride Control and are not compatible with this kit.
- Does NOT fit factory wheels. 20-inch or larger aftermarket wheels are required.
- Wheels must feature 4.5" backspacing to fit properly. Please test fit wheels prior to installation.
- Some aftermarket wheels may require a 0.25" wheel spacer (Rough Country #1065).
- Installation requires cutting and drilling. A strut compressor is necessary; plan 8–10 hours for completion.
