UMI’s  rear upper control arms are a direct bolt-on replacement designed to minimize  wheel hop and improve traction while helping track consistency. These control  arms are constructed of drawn over mandrel mild steel tubing measuring 1.250"  OD x 0.120" wall thickness, CNC machined and fully TIG welded for the  utmost in strength. Control arms feature Energy Suspension polyurethane bushings;  zinc plated steel sleeves and on-car grease-able grease fittings. Adjustability  allows for correctly setting vehicle pinion angle. Pinion angle adjustments are  a must when wanting to lower your track 60-foot times, increase traction and  reduce unwanted wheel hop. The high quality Teflon lined spherical rod end  allows for a bind free operation and allow the suspension to articulate  correctly. The polyurethane bushing side is designed to be bolted to the  chassis side of the vehicle helping to eliminate road noise and maintaining  ride comfort. Note: The 1975 Vega  Cosworth and other H-Bodies in 1975 used a panhard bar/torque arm set-up. If  your vehicle is a 1975 model please verify your vehicle has rear upper control arms.
