6 Inch Lift Kit | Mono Leaf Rear | Vertex | Gmc Sierra 1500 2wd (2025-2026)

Built for GMC Sierra 1500 2WD owners who want commanding stance and tire clearance without sacrificing suspension geometry, this 6-inch lift kit combines factory-angle engineering with the strength to handle 35"–37" tires. Rough Country's Vertex suspension preserves ride quality by keeping control-arm angles close to OE specifications — steel knuckles and drop crossmembers work together to maintain suspension health while you gain real height.

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 | Mono Leaf Rear — Complete rear-lift platform engineered for 2025–2026 Sierra 1500 2WD, featuring mono-leaf blocks and hardware to preserve factory geometry at the rear axle.
• 6in Kit Dr Knuckle Box — Driver-side steering knuckle assembly with integrated caster correction; reduces control-arm angle to maintain OE suspension angles under load.
• 6in Kit Ps Knuckle Box — Passenger-side steering knuckle assembly, matched to driver side for balanced handling and wheel alignment.
• 6in Kit Crossmember Box — Drop-style front crossmember; repositions suspension pickup points to keep strut geometry factory-near while achieving full 6-inch lift height.
• FR Full Skid — Heavy-duty front underbody protection and structural support; shields components from trail hazards and distributes suspension loads.
• Vertex 2.5 Adj FR Lh 6in — Left-front Vertex 2.5-inch adjustable-height shock; allows fine-tuning of ride height and handles the new load path after lift installation.
• Vertex 2.5 Adj FR Rh 6in — Right-front Vertex 2.5-inch adjustable-height shock; matched pair with left unit for consistent front suspension performance.
• Vertex 2.5 RR 7 In — Pair of rear Vertex 2.5-inch shocks (qty 2); support the mono-leaf rear blocks and maintain damping over the added height and tire load.

Important notes

• Denali models not compatible — Kit does not fit GMC Sierra 1500 Denali because those vehicles are equipped with Adaptive Ride Control; different suspension architecture requires a different lift solution.
• Factory wheels cannot be used — OE wheels will not clear the lifted suspension and tires; 20-inch or larger aftermarket wheels are required.
• Backspacing and offset critical — Wheels must feature 4.5-inch backspacing to fit without interference. Some aftermarket wheels may require a 0.25-inch wheel spacer (Rough Country #1065). Test fit wheels prior to final installation.
• Cutting and drilling required — This is not a bolt-only install; minor frame and suspension modifications are necessary for proper fitment.
• Strut compressor needed — Professional equipment is required to safely disassemble and reassemble front strut assemblies during installation.
