UMI's flagship 3032-1's are designed to  make your G-Body car handle like a slot car. These arms have two key features  above and beyond UMI's already impressive fabricated lower a-arm; Delrin  bushings and 1/2" taller-than-stock ball joints. The Delrin bushings provide  bind-free, precise motion. This results in smooth travel and the ultimate in  steering precision.  The 1/2" taller lower ball joint lowers the car  1/2", adds 1/2" of much needed spindle height and corrects bump steer  all in one neat package. 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 3032-1 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, and premium  1/2" taller-than-stock 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, P/N 3056-2  (corner carving, auto-x) or 3056-3 (ultimate handling, road race). UMI  Performance lower a-arms are shipped fully assembled and ready for  installation. Designed and manufactured with pride in Philipsburg, PA -  USA.
