Built for Chevy Silverado 1500 owners who want a commanding stance and serious off-road capability — this 6-inch suspension lift combines factory-geometry preservation with enough tire clearance to run 35" to 37" rubber. A full front and rear overhaul with steel knuckles, drop crossmember, and N3 struts keeps your truck planted while you climb.
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) — rear suspension foundation with mono-leaf architecture to maintain factory-like geometry and durability.
- 6-inch Driver and Passenger Knuckle Boxes — heavy-duty cast knuckles engineered to reduce CV angles and preserve steering geometry.
- 6-inch Crossmember Box — drop-design component that maintains suspension angles under lift height.
- Front Full Skid Plate — underbody protection for articulation and trail work.
- N3 Shock Pair — nitrogen-charged rear shocks tuned for the 6-inch height.
- Loaded Strut Pair (6-inch) — front struts with integrated upper spacers for lift and ride control.
Important notes
- Requires cutting and drilling during installation.
- Does NOT fit LT Trail Boss, Custom Trail Boss, or ZR2 models — these are equipped with factory 2-inch lifts and/or Multimatic DSSV dampers incompatible with this kit.
- Does NOT fit factory wheels. Aftermarket wheels (20-inch or larger) are required with a minimum of 4.5-inch backspacing. Some wheels may need a 0.25-inch spacer (#1065).
- Test-fit wheels before finalizing your order to confirm clearance.
