2001-2010 GM HD 4.5" FOX 2.5 Performance Coilover Conversion (BDS742FDSC)

Convert your Chevy Silverado and GMC Sierra 2500 / 3500 HD to coilovers with this BDS FOX 2.5 conversion kit, compatible with existing BDS 4.5" lift kits. BDS provides a bolt-on frame bracket for the coilovers in the shock mount location with a weld-in support gusset for the upper mount. It replaces the factory torsion bars and upgrades the upper and lower control arms: tubular performance UCAs with 1.5" OD x .120-wall construction, indexed ball joint cup, durometer-specific bushings and greaseable ball joints, plus fully boxed, internally gusseted high-strength lower arms. The FOX 2.5 Factory DSC shocks include a remote reservoir and offer 10 low-speed and 12 high-speed compression levels.
