Built for Chevy Avalanche 1500 owners who want a commanding ride height and aggressive stance. This 7.5-inch lift kit combines geometry-correcting knuckles and loaded N3 struts to deliver a level, planted platform without compromising ride quality. Supports tire sizes up to 40 inches, opening real options for off-road rubber and visual impact.
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
- Knuckles — Precision-machined geometry correctors that restore proper caster and camber angles after the lift, ensuring tire wear stays even and steering feel stays true.
- Loaded Strut Pair (7.5") — Factory-tuned N3 struts pre-assembled with springs, delivering smooth damping on street and trail without the rattle of loose internals.
- Crossmember Box — High-clearance design maximizes ground clearance while maintaining factory suspension mounting geometry; requires no differential modification.
- Lift Hardware Kit — All laser-cut brackets, fasteners, and spacers engineered for precision fit; CAD-validated to OEM tolerances.
- Rear Subframe Yoke Kit — Driveline alignment component that maintains proper pinion angle and drivetrain health without modification to the stock differential mounts or exhaust.
Important notes
- Does NOT fit models equipped with Auto Ride Control, Auto Leveling suspension, or electric power steering.
- 4WD models with all-wheel-drive must be converted to 2WD (driveline modification required) — 2WD Avalanche 1500s bolt straight on.
- 18-inch or larger wheels are mandatory; stock wheel fitment will not clear the suspension geometry.
- Minor cutting and drilling of the frame is required during installation.
- Recommended tire range is 37–40 inches; consult installation instructions for specific tire/wheel combinations to avoid rub or suspension interference.
