UMI Performance 91-96 Impala SS Adjustable Extended Length Upper Control Arms- Rod Ends

If you're working on a 1991-1996 Chevrolet Caprice or Impala SS and want to get your rear wheels perfectly centered in the wheel wells, these adjustable upper control arms from UMI Performance are a solid option. They're designed to extend the stock length by 5/8 inch, which is often enough to correct wheel positioning, but they also include an additional 1/2 inch of on-car adjustability. This means you can fine-tune the wheel centering and even adjust your pinion angle without having to remove the control arms from the car.

These control arms are built tough. They use strong DOM tubing for the main arm, with CNC-machined mounting points made from 0.250-inch mild steel. For the adjustment mechanism, UMI uses a 4140 Chrome Moly solid adjuster, which is heat-treated for durability. The arms come pre-set at the 5/8-inch extended length, and the adjustment process is straightforward. They also feature high-quality, Teflon-lined spherical rod ends with self-lubricating races, which help reduce noise and vibration for a quieter ride compared to some other brands. UMI also includes greaseable polyurethane bushings for smooth operation. These are designed to work with extended lower control arms, so keep that in mind for your build.
