BDS 7 Inch Lift Kit | FOX 2.5 Coilover Conversion | Chevy Silverado & GMC Sierra 2500HD (2001-2010) 2WD | Carrier Above Crossmember

This configuration is designed for 2001–2009 2WD HD trucks where the carrier bearing is mounted above the crossmember. If your carrier bearing sits above the crossmember, this is the correct selection.

Overview

This 7-inch suspension lift kit with FOX 2.5 Coilover conversion is designed for 2001–2010 Chevy Silverado and GMC Sierra 2500HD 2WD trucks. The kit is engineered to improve stance, performance, and capability, providing clearance for tires up to 35 inches. It incorporates a high-clearance design that maximizes ground clearance and off-road protection while correcting suspension and steering geometry for improved on-road handling.

Up front, the kit uses FOX 2.5 coilover shocks, heavy-duty tubular upper control arms, high-arched 1/4-inch-thick steel crossmembers, a multipiece differential relocation bracket, and heavy-duty skid plates. CNC-machined ductile iron steering knuckles correct steering geometry at the new ride height. Sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all required hardware are included. In the rear, the kit utilizes a lift block that installs in place of the factory block, new precision-tuned U-bolts, and FOX 2.0 Performance Series shocks.

Features

• FOX 2.5 coil-overs with improved damper performance over stock; DSC adjuster allows easy high-speed and low-speed compression tuning for optimal performance in any terrain
• Remote reservoir on FOX 2.5 coilovers provides additional fluid capacity to keep shocks running cool under demanding conditions
• Performance upper control arms (UCAs) increase strength and allow for more suspension travel; built with 1.5" OD x .120-wall tubular construction with an indexed ball joint cup for additional down travel and camber adjustment
• High-clearance design with no torsion bar drop maximizes ground clearance
• Robust CNC-machined ductile iron steering knuckles maintain ESC system compliance and correct geometry at lift height
• Heavy-duty 1/4-inch-thick, laser-cut crossmembers paired with a front skid plate system that bolts together to create a rigid subframe with added off-road protection
• Multipoint differential relocation brackets secure the front axle and improve CV angles
• Durometer-specific rubber bushings at frame mounting ends for maintenance-free UCA operation; greaseable ball joint at the knuckle end for smooth, quiet operation and durability
• UCAs finished in durable black powder coat with billet aluminum dust cap
• Factory Protection Plus drivetrain warranty included

Important Notes

• Torsion bar tool required to load/unload the torsion bars
• Some welding required
• Requires frame bracket modification and differential mount modification
• Traction bars will not fit standard cab/short box models and are designed to work on vehicles with 4" to 8" of lift

• Not recommended for Suburban or Yukon models with AutoTrac Transfer Case
• Does NOT work with rear Autoride-equipped SUVs
• The 2001–2009 2WD HD was available with two different carrier bearing crossmember configurations — select the correct variant based on whether your carrier bearing is mounted above or below the crossmember
