it's pretty much a rite of passage to get your big diesel truck higher in the air, and CST Suspension has a bunch of lift kits, leveling kits, and other suspension components that let you fit on bigger tires, provide better handling, and can improve off-road performance all in one place. CST offers up a variety of Duramax suspension upgrades and Cummins suspension upgrades that will improve your truck's handling while giving it more ride height. CST even offers up Duramax coilover conversion kits to replace their torsion bars and give them awesome handling and off-road performance.
