Fits: 2020 thru 2024 Chevy Silverado/GMC Sierra 2500HD/3500HD L5P Duramax Diesel 

Based around the tried and true high clearance technology that has made BDS the go to for GM suspension lifts, these systems have been designed from the ground up for the 2020 HDs to get the more out of these trucks with the most ground clearance on the market. These new 5" lift systems join existing 3" and 6.5" options bringing comfortable, handling, and capability with clearance for up to 37" tires. While some companies build "kits" to fit larger tires, BDS Suspension prides itself in engineering complete suspension systems designed to take your vehicle's performance to the next level while retaining OE-level functionality.

At the heart of this new 5" systems BDS utilizes a pair of 1/4" thick laser cut high clearance crossmembers to maximize clearance and provide a solid mounting point for the OE lower control arms. These paired with the heavy duty front skid plate create a rigid subframe while adding protection for vital steering and driveline components. In place of the factory steering knuckles are a pair of specially designed ductile iron replacement steering knuckles are supplied to maintain proper steering geometry for ESC system compatibility. The front differential is repositioned with BDS's multipoint relocation bracket system to secure the front differential to keep CV axle angles at a minimum. To help maximaze clearance a pair of torsion bar relocations brackets are supplied to mount to the lower control arms to retain the factory high clearance frame mounted crossmember. A pair of BDS-branded sway bar drop brackets used to correct the operating angle of the factory sway bar along with extended length braided stainless steel brake lines. Rounding out the front of this kit are FOX 2.0 performance series IFP shocks.

In the rear of this 5" lift system 4.5" lift blocks and longer u-bolts to lift and level the stance. Also included, BDS supplies brake line and ABS line relocation brackets allow the use of factory brake lines. Lastly a matching set of FOX 2.0 performance series IFP shocks are supplied to compliment the front setup.

Includes:

• Necessary hardware 

Notes:

• Requires frame bracket modification.
• Torsion Bar Tool required to load/unload torsion bars, The GM specified tool is #CH48809.
• Models with two-piece rear driveshafts will require a carrier bearing drop kit.
• Factory 17-18" wheels cannot be reinstalled due to tie rod end interference, stock 20" wheels can be reinstalled with up to a 35x12.50 tire.
• In some cases vehicles used in 4WD on the highway regularly 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 that tested 6.5" lift height.
• U-bolts will not work vehicles equipped with top-mounted overload springs or add-a-leafs.
• Compatible with gas or diesel models.
• Compatible with standard models as well as AT4 models.
• Some minor trim will be required with certain wheel/tire combination. This is normal with most aftermarket tire/wheel fitment on Chevy/GM trucks. Trimming will normally included the bottom edge of the inner fender shrouds and/or lower corner of 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.
