Notes

• Models with two-piece rear drive shafts will require a carrier bearing drop kit. (BDS121612)
• 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.
  
• Dually Models will require aftermarket 20" wheels with a max 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.
• 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.
