UMI Performance 91-96 Impala SS Adjustable Extended Length Upper Control Arms- Poly 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 add 5/8 of an inch in length right out of the box, and you can fine-tune them even further with an additional 1/2 inch of adjustment. This adjustability is key for getting that ideal stance and ensuring your tires aren't rubbing on the fender liners.

These control arms are built tough. They're made from strong DOM tubing, and the adjusters are crafted from heat-treated 4140 Chrome Moly, which is a strong steel alloy. UMI includes grease-able polyurethane bushings from Energy Suspension, which help keep things quiet and smooth while still offering good control. The adjuster itself is a solid piece, making on-car adjustments for length and even setting your pinion angle a straightforward process. They come pre-set at that 5/8 inch extended length, so you're already ahead of the game when you start the installation.

Keep in mind that when you're adjusting the rear suspension geometry like this, especially if you're changing the ride height significantly, you might need a longer driveshaft. It's always a good idea to check your specific setup and consult the manufacturer's notes for any potential requirements.
