UMI lower A-Arms are fabricated from USA DOM tubing with CNC notched tube ends for a precision fit. They are jig built to maintain accuracy and bolt on correctly every time. All critical areas are TIG welded for superior strength and a clean look. UMI’s lower A-Arms also feature improved ball joint angle for lowered vehicles and the design provides additional tire clearance. UMI P/N 3031 lower a-arms include greaseable fluted polyurethane bushings for a smooth quiet ride. They come preloaded with polyurethane bump stops, steering stops and premium ball joints. UMI’s extensive testing on the street, drag strip and skid pad ensures a quality product able to with stand all types of abuse. UMI lower A-Arms are designed to work with factory springs, lowering springs and most coil over kits without changing the a-arms. For exceptional handling and performance we recommend combining with UMI upper a-arms, part # 3033-2. UMI’s lower a-arms are shipped fully assembled and ready for installation. Designed and manufactured with pride in Philipsburg, PA - USA.
UMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street/strip use.
