3.5 Inch Lift Kit | Mono Leaf Rear | N3 Struts | Gmc Sierra 1500 (25-26)

Built for GMC Sierra 1500 owners who want a balanced lift with room for 33–35 inch tires, this 3.5-inch suspension lift kit delivers the perfect sweet spot between a simple level and a full 6-inch build. Rough Country's engineered geometry preserves factory suspension angles using forged aluminum upper control arms — so your Sierra handles like it should, just higher and more capable.

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

• N3 Shock Pair — Nitrogen-charged shocks tuned for a balanced ride and consistent dampening across on-road and light off-road use.
• Loaded Strut Pair — Pre-assembled 3.5-inch struts ready to bolt in, saving hours of labor and ensuring correct ride height from day one.
• Forged Upper Control Arms — Heavy-duty aluminum links that maintain factory suspension geometry at the new lift height, preserving steering feel and tire wear patterns.
• Strut Kit Box — All hardware, fasteners, and brackets needed to mount the struts and control arms to your Sierra's frame and spindles.

Important notes

• Not compatible with Denali or Denali Ultimate — vehicles equipped with Adaptive Ride Control cannot use this kit.
• Not compatible with AT4 or AT4X — these trims come with a factory 2-inch lift and Multimatic DSSV dampers that conflict with this suspension.
• Diesel models excluded — due to engine weight variance, Rough Country strut options do not fit diesel powerplants.
• Requires cutting and drilling — installation involves modification to the vehicle frame and mounting points.
• Strut compressor needed — professional-grade spring compressor is required to safely disassemble and reassemble the struts during install.
