Tired of looking at hammered, crusty lower a-arms with cracked ball joint bosses? UMI has the solution with brand new modern tubular lower a-arms. UMI lower A-Arms are fabricated from DOM tubing with CNC machined 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. Our P/N 4032 lower a-arms include greaseable, UMI designed and manufactured Delrin bushings. Delrin bushings offer supremely smooth suspension action and precision operation while still providing some insulation from road noise. They come preloaded with polyurethane bump stops, polyurethane spring isolators 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 coil over kits without changing the a-arms. For exceptional handling and performance we recommend combining with UMI upper a-arms, part # 4033-1. UMI Performance lower a-arms are shipped fully assembled and ready for installation.
