BDS 6 Inch Lift Kit | Chevy Silverado/GMC Sierra 2500HD 4WD (2001-2010) | 5" Block Kit | FOX 2.0 Performance Series | Standard Knuckle

Configured with a 5-Inch Rear Block Kit, FOX 2.0 Performance Series shocks, and Standard Knuckle. The 5-inch cast iron rear block replaces the factory 2-inch block, netting 3 inches of rear lift to level the vehicle, correcting pinion angles, and maintaining factory payload ratings. FOX 2.0 shocks feature a 2-inch impact-extruded aluminum body, internal floating piston monotube design, CNC-machined 6061-T6 aluminum mounting ends, and a massive 5/8-inch hard chrome-plated heat-treated alloy steel shaft with application-specific valving. The standard knuckle widens the track width but does not affect the turning radius.

Overview

The BDS 6-inch lift kit is designed to improve stance, performance, and capability for the 2001–2010 Chevy Silverado and GMC Sierra 2500HD 4WD. For maximum ground clearance, BDS engineered a No Torsion Bar Drop System where the torsion bars are mounted directly to the top of the lower a-arm, eliminating the need to drop the torsion bar cross-member. This kit includes everything necessary to accommodate up to 35-inch tires and takes advantage of BDS's high-clearance design for improved ground clearance, strength, and off-road protection, while correcting suspension and steering geometry for on-road handling.

Up front, the kit utilizes torsion bar relocation brackets, high-arched 1/4-inch thick steel crossmembers, multi-piece differential relocation brackets, and heavy-duty skid plates. Steering geometry is corrected at the new taller ride height with CNC-machined ductile iron steering knuckles. Sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all necessary hardware are included. In the rear, the kit is available with either a replacement lift block or a full Glide-Ride leaf spring option, along with new u-bolts, brake line brackets, and a choice of shocks.

Features

• High-clearance design with no torsion bar drop maximizes ground clearance
• Robust CNC-machined ductile cast iron steering knuckles maintain ESC system compliance and factory tie rod end compatibility
• Heavy-duty 1/4-inch thick laser-cut steel high-arched crossmembers
• HD skid plate system for improved off-road protection
• Multi-point differential relocation brackets to secure the front axle and improve CV angles
• Choice of NX2 Nitro Series or FOX 2.0 Performance Series gas shocks
• Rear option available as 5-inch cast iron block kit or Glide-Ride leaf springs
• Factory Protection Plus drivetrain warranty included
• Accommodates up to 35-inch tires

Specifications

• Lift Height: 6 inches (front); rear lift leveled via block kit or leaf spring option
• Front crossmembers: 1/4-inch thick laser-cut steel, high-arched design
• Steering knuckles: CNC-machined ductile cast iron
• Rear block: 5-inch cast iron, replaces factory 2-inch block, nets 3 inches of rear lift
• Rear leaf springs: Multi-leaf progressive design, maintains factory payload weight ratings
• Shock options: NX2 Nitro Series (nitrogen-charged twin-tube, 10-stage velocity-sensitive valving, 1-3/8-inch high-flow piston, silver powder coat finish) or FOX 2.0 Performance Series (2-inch impact-extruded aluminum body, internal floating piston monotube design, CNC-machined 6061-T6 aluminum mounting ends, 5/8-inch hard chrome-plated heat-treated alloy steel shaft)
• Track width option: Standard Knuckle (widens track width, no change to turning radius) or Narrow Track Knuckle (reduces track width change by ~1.5" overall, slightly increases turning radius)

Installation

• Estimated Time: 8–10 hours
• Difficulty: Difficult
• Tools Required: Cut-Off Wheel or equivalent, Grinder/Sanding Disc, Reciprocating Saw, Torsion Bar Unloading Tool, Welding Equipment

Important Notes

• Torsion bar tool required to load/unload the torsion bars.
• Some welding is 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.
• Will NOT work on long bed models.
• 20" wheels with 5" to 5-3/4" backspacing are recommended to reduce trimming.
• Gas models require exhaust modification.
• The narrow track knuckle will increase the minimum full-lock turning radius; you will not be able to turn as sharply.
• For a tail-high stance, use #119157 add-a-leaf with the block kit or #069207 with the leaf spring kit.
• Dually applications will require custom u-bolts.
• Leaf spring option does not work with SUV applications.
