These upgrade kits are compatible with existing BDS 6-inch lift kits allowing for seamless integration.

The tubular performance upper control arms specially designed by BDS for this system work seamlessly with the 2.5 coilovers. The new lower control arms on the other hand are built from high-strength steel fully boxed and internally gusseted to complement the uppers.

The DSC adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs offering 10 separate low-speed and 12 high-speed compression levels with a black anodized aluminum reservoir to increase cooling efficiency. Built for strength performance and increased travel these upper control arms are ready to bolt-in with most leveled/lifted trucks.
