6 Inch Lift Kit | N3 Struts | Gmc Sierra 1500 2wd/4wd (2019-2024)

Built for GMC Sierra 1500 owners who want a bold, leveled stance and the clearance to fit 35–37 inch tires, this 6-inch suspension lift kit from Rough Country combines front-to-rear leveling with premium cast knuckles and a high-clearance crossmember. You get the aggressive look, improved ground clearance for trail performance, and a bolt-on design that preserves factory geometry and handling.

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

• Driver and passenger-side knuckle boxes — precision-cast components that maintain factory track width while supporting the lifted suspension geometry.
• High-clearance crossmember — engineered to maximize ground clearance and off-road capability without compromising suspension articulation.
• Universal kit box — hardware and fasteners for secure, bolt-on assembly.
• Front skid plate — heavy-duty fabricated protection that adds chassis strength under the lifted frame.
• N3 shock pair — nitrogen-charged rear dampers tuned for the 6-inch lift height.
• Loaded strut pair — pre-assembled front struts (6-inch trim) ready to bolt in with no disassembly required.

Important notes

• Does not fit 2019 "Classic" models (2018 body style), Denali, Denali Ultimate, AT4, or AT4X variants.
• Diesel models — Rough Country replacement strut options do not work on diesel engines due to motor weight variances.
• Wheel fitment — requires 20-inch or larger aftermarket wheels with 4.5-inch backspacing. Does not fit factory wheels. Some wheels may require a 0.25-inch spacer.
• Installation — requires cutting and drilling. No strut disassembly or differential trimming needed.
• Tire range — designed to support 35–37 inch tires on proper wheel offsets. Test-fit wheels before installation.
