Take your 2020-2024 Chevy Silverado and GMC Sierra 2500 HD 4WD to the next level by installing this 6.5-inch lift kit by BDS Suspension. For maximum ground clearance, BDS designed 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.
Designed to improve the stance, performance, and capability this kit includes everything necessary to set your truck up right with clearance for up to 38 inch Tires.
This kit takes advantage of BDS's tried and true high-clearance design for improved ground clearance, strength, and offroad protection while correcting suspension and steering geometry for great on-road handling characteristics.
Up front, the kit utilizes torsion bar relocation brackets, high-arched 1/4-inch thick steel crossmembers along with a multipiece differential relocation brackets and heavy duty skid plates built for offroad protection.
Steering geometry is corrected at the new taller ride height with CNC-machined ductile iron steering knuckles. These combined with the provided sway bar drops, stainless steel brake lines, supplied hardware and more provide a comprehensive front suspension lift ready for whatever you throw at it.
In the rear BDS offers replacement lift blocks and u-bolts to lift and level that stance. The lift block installs in place of the stock block and retains ride quality and load capacity. Also included, BDS supplies brake line and ABS line relocation brackets allow the use of factory brake lines. Lastly are a matching set of NX2 Nitro or FOX 2.0 Performance Series shocks.
FOX Performance Elite
FOX 2.5 Performance Elite shocks offer next level performance for on-road comfort and off-road comfort capability. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter shocks are built for abuse and packed with race-proven technology.
They include a remote reservoir for additional fluid capacity to keep your shocks running cool so you can push the limits in the rough terrain. The Dual Speed Compression Adjust adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.
Heavy Duty Steering Knuckles
BDS corrects steering geometry at the new taller ride height using a pair of high-strength, CNC machined ductile cast iron steering knuckle design to work with factory tie rod ends to maintain steering angles for proper function.
6 inch Block Kit With Overload
- Front Lift Method: Cross-Member
- Rear Lift Method: Block
- Shocks Included: Yes
- Front Lift Height: 6.5 inch
- Rear Lift Height: 6 inch
- For DRW models, use the w/ overload rear lift option
- Requires frame bracket modification.
- Torsion Bar Tool required to load/unload torsion bars
- Models with two-piece rear driveshafts will require a carrier bearing drop kit.
- Factory 17-18 inch wheels cannot be reinstalled due to tie rod end interference, stock 20 inch wheels can be reinstalled with up to a 35x12.50 Tire.
- In some cases, vehicles used in 4WD on the highway frequently could potentially experience a minor front driveline vibration. If this occurs we recommend replacing the front driveshaft with a dual Cardan style driveshaft.
- Do not install this suspension system in conjunction with any type of torsion bar lift keys to achieve more than the tested 6.5 inch lift height.
- Some minor trim will be required with certain wheel/Tire combinations. This is normal with most aftermarket Tire/wheel fitment on Chevy/GM trucks. Trimming will normally include the bottom edge of the inner fender shrouds and/or the lower corner of the front bumper valance. As a rule of thumb, deeper backspacing and shorter/narrower Tires will reduce/eliminate trimming required.
- Further trimming tips are included at the end of this instruction sheet.
