Associated Comments:

  • Models with two-piece rear drive shafts will require a carrier bearing drop kit. (BDS121612)
  • Do NOT increase coilover preload.
  • For replacement ball joints use service kit BDS081203. Ball joints are directional and must be installed with the ‘dot’ facing either inward or outward on the vehicle otherwise damage may occur.
  • Increase of 1” of track width per side (2” overall) is done to create a better travel range of the suspension to allow more droop travel from ride height along width helping the coilover clear the frame components.
  • Requires frame bracket modification and minor welding
  • Disassembly/assembly of the factory torsion bar system requires the use of a special unloading tool.
  • The GM specified tool # is CH48809.
  • Compatible with diesel models ONLY. Works with standard or AT4 diesel models. The use of thecoilovers on GASengine models is notrecommended due toproviding too much lift.Available preloadadjustment is typicallynot enough to achievedesired ride height.
  • 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 include 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.
  • Dually Models will requireaftermarket 20" wheels with amax tire size of 285/60/20.
  • Factory 17” 18” and 20” wheels cannot be reinstalled due to upper control arm clearance.
  • Coilover coil has a large amount of preload a coil spring compressor must be used to remove the coil from the coilover. Failure to use a coil spring compressor may result in death or injury.
