Description

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.
