Fits: 2001 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM Duramax Diesel

BDS offers comprehensive coilover conversion upgrade kits for Chevy Silverado and GMC Sierra 2500/3500 HD, seamlessly integrating with existing BDS 4.5-inch lift kits. Equipped with heavy-duty brackets and FOX 2.5 Coilovers, these kits elevate your vehicle's performance to new levels.

A bolt-on bracket mounts the coilovers to the frame in the shock mount location, reinforced by a weld-in support gusset for the upper mount. Upper and lower control arms are upgraded for enhanced strength and travel, accommodating the new coilovers. Specially designed tubular performance upper control arms by BDS complement the 2.5 coilovers.

FOX 2.5 Coil-Overs offer next-level performance with remote reservoirs for additional fluid capacity, ensuring optimal operation in rugged terrain. The DSC adjuster provides remarkable versatility and precise tuning with 10 separate low-speed and 12 high-speed compression levels, enhancing cooling efficiency with a black anodized aluminum reservoir.

HD Upper Control Arms are built for strength, performance, and increased travel, featuring durable construction with indexed ball joint cups and durometer-specific rubber bushings for maintenance-free operation. Finished in a durable black powder coat, these arms are ready for installation right out of the box.
