2020-2026 GM HD 3" Fox 2.0 Performance Series Coilover (BDS1829FPE)

Engineered for serious truck enthusiasts, this BDS Suspension coilover conversion replaces your GM 2500HD/3500HD's factory torsion bar setup with a modern coil-over design. The 3-inch lift delivers enhanced articulation and travel for both highway comfort and challenging terrain. Reinforced upper and lower control arms optimize suspension geometry while maintaining durability under demanding conditions. This performance-focused upgrade unlocks improved handling characteristics and greater off-road capability without compromising daily drivability.

Features

• Converts torsion bar front suspension to a Coil-over for improved ride comfort.
• Includes BDS upper and lower control arms.
• FOX 2.5 Performance Elite series DSC coil-overs offer improved damper performance over stock.
• BDS performance UCAs increase strength and allow for more suspension travel
• Factory Protection Plus drivetrain warranty included Easy,
• 100% Bolt on installation
  
• Provides added control and comfort for on-road use or more aggressive damping for use off-road

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.
  
• 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.
