2001-2010 GM HD 6.5" FOX 2.5 Performance Coilover Conversion (BDS741FDSC)

This BDS 6.5" coil-over conversion upgrade makes it effortless to convert your Chevy Silverado / GMC Sierra 2500/3500 HD from standard lifted suspension to coil-overs, and is compatible with existing BDS 6.5" lift kits. It provides a bolt-on frame bracket to mount the coil-overs in the shock mount location with a weld-in support gusset to reinforce the upper mount. Beyond replacing the factory torsion bars, the control arms are upgraded with BDS tubular performance uppers (1.5" OD x .120-wall, indexed ball joint cup) and fully boxed, internally gusseted high-strength steel lowers. The FOX 2.5 Factory remote-reservoir shocks are race-proven and tuned out of the box, with a Dual Speed Compression adjuster offering 10 low-speed and 12 high-speed compression levels.
