6 Inch Lift Kit | Ntd | Chevy Avalanche (02-06)/suburban 1500 (00-06)

Built for Chevy Avalanche and Suburban 1500 owners who want serious ground clearance without sacrificing ride quality — this 6-inch lift kit uses Rough Country's improved Non-Torsion Drop (NTD) design to raise your truck while keeping factory driveline geometry intact. Supports up to 35"–37" tires and maintains the smooth, composed ride you expect on highway and trail.

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

• 6" NTD Bracket Box — Raises the front end using non-torsion drop brackets that keep bars in factory location for clean integration and precise fitment.
• Kit Box (front components) — Includes lifted knuckles, CV spacers, sway-bar links, and front crossmember bracket for proper geometry and steering clearance.
• NTD Crossmember Kit Box — High-clearance crossmember engineered to tuck components at optimal angles and maximize ground clearance.
• N3 Kit Box (rear) — Nitrogen-charged monotube shocks calibrated for 6" lift; maintains comfort and control on road and off-road.
• Driver & Passenger Knuckles — Lifted front knuckles restore proper caster angle and suspension geometry after the lift.
• Rear Coil Springs & Differential Drop Bracket — Matched rear springs deliver the 6" lift; drop bracket positions the differential for optimal drivetrain angles and reduced wear.

Important notes

• 17-inch or larger wheels are required — stock wheel sizes will not fit after the lift.
• Frame bracket modification is required for proper installation.
• Does not fit models equipped with factory auto ride or auto-leveling suspension.
• Factory torsion bar compression stops are reused; a torsion bar removal tool is recommended to ease installation.
• Auto Trac-equipped models are fully compatible with this lift.
