UMI Performance lift bars replace your stock rear control arms, adding tremendous track gains, while not affecting ride height and keeping ride quality at its best. These lift bars are designed to work with axle torque to load the chassis of the car, forcing the rear wheels downward, while pushing the tires into the ground for harder launches and improved 60 ft. times. These bars are designed to greatly improve traction and reduce unwanted wheel hop. Constructed from boxed mild steel tubing, they feature a 0.120 in. wall and 0.188 in. thick mounting plates and are completely CNC-machined for exact tolerances and a superb fit. These lift bars feature greasable Energy Suspension bushings that reduce bushing deflection but still make these arms 100 percent streetable. Each lift bar features the correct provisions for adding a stock or aftermarket sway bar. Sway bar holes are placed in the correct pattern to maintain the sway bar level with the rear-end. All sway bar holes are reinforced with a 0.120 in. thick steel sleeve wall, TIG-welded, and then sanded into place. The rear mounting brackets feature two settings that allow the lift bar to be lowered 2 in. or 3 in., depending upon user preference and the vehicle's suspension setup. These lift bars also correct lost geometry and instant center on a lowered vehicle. Add a set of our adjustable upper control arms for maximum rear suspension setup!

Lakewood combined their experience and the latest technology in drag racing to develop shocks and struts that are superior to all other drag shocks and struts available. They provide the correct weight transfer on the initial launch and then bring the front-end down quickly for aerodynamic purposes. This transfer will result in lower ETs and keep the rear-end loaded for maximum traction.

They're a bolt-in shock relocator kit that rotates each shock 90 degrees, while leaving them in the same location. The TIG-welded lower bracket holds the shock in double-shear so that it's able to pivot freely about the lower bolt. UMI Performance shock mount kits provide your vehicle with improved structural integrity and unrestricted movement. Refer to application tab for fitment.

When discussing anti-roll or stabilizer bars, many driving experts consider factory stock end links to be the "weak links" in the system, with a tendency to bend. Often, they'll upgrade to these heavy-duty Whiteline sway bar end links to eliminate preload via the adjustable center-to-center length feature. Many Whiteline models are constructed with aluminum bodies and heavy-duty steel ball joint ends that not only adjust, but also rotate to any angular combination. Bottom line: stronger end links equal improved suspension and handling. Whether you're servicing a front, rear, or universal sway bar assembly, choose the Whiteline end links that fit your car or truck.
