2003-2013 Cummins 3" Coilover Lift Kit (BDS690F)
Upgrade your Cummins strength, design, and durability with this Coilover conversion; which gives you a full 8" of front suspension travel in order to maximize the performance of the short arm suspension setup alongside 3" of ride height increase! This new 3" system is built as an upgrade to the popular 691H kit 3" Dual Rate Coil lift system with the Coilovers replacing the 3" coil springs and working alongside the existing front and rear box kits.

Improve ride quality and capability with the FOX 2.0 performance series IFP shocks. Specially designed for BDS lift systems, these FOX 2.0 aluminum body shocks offer improved cooling capacity and corrosion protection. These shocks use race-proven vehicle-specific valving along with an internal floating piston (IFP) monotube design to separate the shock oil from high-pressure nitrogen to eliminate aeration and maximize performance on/off-road.
