UMI Performance sway bars are designed to reduce body roll and understeer and increase cornering capabilities, resulting in a more balanced suspension. The front sway bar is more rigid than the factory model and comes complete with new polyurethane end links and greaseable sway bar bushings. The rear sway bar is supplied with new Grade 8 mounting hardware and locknuts. UMI Performance sway bars are manufactured from 4140 chromoly steel—and formed as one piece to ensure maximum strength and performance. Each rear sway bar is heat-treated and heat-formed to maintain longer memory than a cold bent bar, while the front sway bar is CNC-bent for a precise and accurate fit every time. Order the kit recommended for your vehicle.

Say goodbye to leaving the line sideways with UMI's rear drag sway bars. These kits are designed to get your vehicle consistently leaving the line straight, eliminate torque steer, and drastically improve 60 ft. times. The included adjustable end links allow vehicle preload to be set for straight launches. UMI's end links feature heavy-duty chromoly rod ends, which have a hard chrome plating and a PTFE self-lubricating race. The end links attach to the drag bars using 5/8 in. Grade 8 bolts and locknuts. These heavy-duty rear drag bars attach to the axle tubes using high-strength 4140 chromoly U-bolts, 3/16 in. thick fabricated mounts, and Energy Suspension bushings. The fabricated bushing mounts feature CNC-machined teeth to prevent sliding on the axle. Unlike some competitors' designs, UMI's sway bar mounts also feature gussets welded on each end to prevent the brackets from spreading while tightening.

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!
