Overview
BDS offers complete coilover conversion upgrade kits for the Chevy Silverado and GMC Sierra 2500HD/3500HD, allowing you to convert your standard lifted suspension into coilovers. These kits include heavy-duty brackets and FOX 2.5 Performance Elite Coilovers, and are compatible with existing BDS 4.5-inch and 6.5-inch lift kits for seamless integration. A bolt-on bracket mounts the coilovers to the frame at the shock mount location, and a weld-in support gusset reinforces the upper mount. In addition to replacing the factory torsion bars, both the upper and lower control arms are upgraded for enhanced strength and travel to accommodate the new coilovers.
