Important fitment notes

1. Requires frame bracket modification.
2. Torsion Bar Tool required to load/unload torsion bars, The GM specified tool is #CH48809.
3. Models with two-piece rear driveshafts will require a carrier bearing drop kit.
4. 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.
5. 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.
6. Some minor trimming 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.
7. Will NOT work with AT4X or ZR2 models, lower control arm profile is different
   

BDS warranty coverage is for the original retail purchaser with proof of purchase. BDS hard parts and bushings have lifetime replacement coverage; finish and normal wear are excluded.

BDS NX2 and BDS/FOX Performance Series shocks have limited lifetime coverage excluding normal wear and oil seals. At BDS’s discretion, qualifying leaking seals less than two years old may be considered for repair or replacement.

FOX proprietary shocks and coilovers follow FOX warranty terms rather than the BDS warranty. Qualifying leaking seals less than one year old may be considered; other FOX concerns follow the FOX service process.

Properly maintained ball joints and tie-rod ends less than three years old may qualify, subject to the manufacturer’s conditions.

Remedies are repair or replacement at BDS’s discretion. Eligible warranty ground shipping is covered; removal, installation, expedited freight and consequential costs are excluded.
