If you've got an HD Duramax truck it's possible it could use some new suspension! Why not lift it while you're in there with this BDS 4.5" Coilover conversion system. This system eliminates your torsion bars and gives you a much more adjustable alternative. This system builds on the BDS high clearance system design offering more ground clearance, corrects suspension, steer, driveline geometry, and pairs it with the race-proven pedigree of Fox 2.5 factory series Coilovers to soak up the harshest terrain while still offering comfort and control for your daily commute.
