2001-2010 GM 2500HD 2WD/4WD


The CST 9"-11" Suspension Lift Kit CSS-C3-9 provides clearance for larger tires, durability, and an improved ride in your 2001-2010 GM  2500HD Pickup. The CST Suspension Lift Kit requires no cutting of the differential or welding and will keep the factory track width. This CST System will drop down the factory suspension a true nine inches, ensuring that the factory steering and control arm geometry will remain within factory specifications. 
Like many of the other CST Lift Kits, the CSS-C3-9 kit includes the unique one-piece high-clearance sub-frame with strut bar supports, supported upper control arm mounts, steering drop down with heim jointed support linkage, 4WD differential drop down, or 2WD cross bar all in a high quality gloss black powdercoat finish. 
All CST Sub-Frame Style Lift Kits include a new center-link with heim supports off of the sub-frame to reduce wear and tear and add stability to idler and pitman arms. This lift kit is for the front only. Rear leaf springs or a block and add-a-leaf kit are required to lift the rear.
