2020-2021 Duramax 5" NTBD Suspension Lift System (BDS766H)

BDS Suspension is now shipping 5" high clearance lift systems for the Chevy Silverado and GMC Sierra 2500HD and 3500 HD trucks. Based on 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 more out of these trucks with the most ground clearance on the market. This new 5" lift systems are the first of many new BDS options to come available for the new trucks bringing you on-road comfort, off-road capability, and clearance for 38" tires.

Tire & Wheel Combinations:

• 37x12.50 w/ 20x9 and 5" - 5.5"
• 35x12.50 w/ 20x10 and 5" - 5.5"
• 35x12.50 w/ 17x9 or 18x9 and 4.5" - 4.625"

Notes:

• Requires frame bracket modification.
• Torsion Bar Tool required to load/unload torsion bars, The GM specified tool is #CH4880
• 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.
• U-bolts will not work in 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 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 lower corner of the front bumper valance. As a rule of thumb, deeper backspacing and shorter/narrower tires will reduce/eliminate the amount of trimming required. Further trimming tips are included at the end of this instruction sheet.
