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 4031 lower a-arms include greaseable polyurethane bushings, premium ball joints, polyurethane bump stops and spring isolators. 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, P/N 4033-1. UMI lower A-Arms are shipped fully assembled and ready for installation. Designed and manufactured with pride in Philipsburg, PA - USA.
