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

If you're looking to dial in the rear wheel alignment on your 1991-1996 Chevrolet Caprice or Impala SS, these adjustable upper control arms from UMI Performance are a solid option. They're built from strong DOM tubing and feature a 4140 Chrome Moly heat-treated adjuster, which is crucial for making precise on-car adjustments. These arms are designed to extend the length by 5/8 inch, helping to center your rear wheels in the wheel wells, especially if you've lowered your vehicle or are running wider wheels. You get an additional 1/2 inch of adjustment beyond that extended length, giving you plenty of room to get everything perfectly aligned and set your pinion angle.

What really makes these stand out is the combination of durable materials and thoughtful design. The CNC machined mounting points ensure they fit right, and the included Energy Suspension polyurethane bushings are greaseable, which helps keep them quiet and long-lasting. UMI ships them pre-set at that 5/8 inch extended length, so you're ready to go, but the adjuster makes fine-tuning easy. They also come with a durable glossy powder coat finish to resist corrosion. Keep in mind that depending on your ride height, you might need a longer driveshaft to accommodate the changes.
