BDS 4 Inch Lift Kit | FOX 2.5 Performance Elite Coil-Over | 2007-2014 Chevy/GMC Avalanche, Suburban, Tahoe, Yukon 1500 4WD | 3 Inch Rear Coil Spacer

This configuration includes a 3 Inch Rear Coil Spacer to level the vehicle at the rear, paired with the FOX 2.5 Performance Elite coil-over setup up front.

Overview

This BDS 4-inch lift kit is designed for 2007–2014 Chevrolet Avalanche, Suburban, and Tahoe and GMC Yukon 1500 4WD trucks. The kit includes everything required to lift the vehicle while maintaining clearance for up to 33-inch tires. BDS's high-clearance design improves ground clearance, strength, and off-road protection while correcting suspension and steering geometry for proper on-road handling. Up front, the kit utilizes full-length replacement strut shocks, high-arched 1/4-inch thick steel crossmembers, a multipiece differential relocation bracket system, and heavy-duty skid plates. CNC-machined ductile iron steering knuckles correct steering geometry at the new ride height. The kit also includes sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all necessary hardware. Rear lift is achieved via precision coil spring spacers, with FOX 2.5 Performance Elite coil-overs providing premium damping performance.
