What is the main benefit of using polyurethane bushings over the original rubber ones?

Polyurethane bushings are much firmer and more resistant to degradation from weather, UV rays, and age compared to factory rubber. This results in a more solid connection for improved handling and a more consistent ride, especially as the original rubber wears out.

What exactly comes in this kit?

This kit includes two high-durometer polyurethane bushings and two accompanying washers. These components work together to replace your worn rear end housing bushings and help prevent unwanted lateral movement.

Are these bushings suitable for daily driving as well as performance use?

Yes, these bushings are designed for both street-driven and track-used vehicles. Their durable construction and improved performance characteristics make them a solid option for a wide variety of driving conditions.

Product Details

These UMI Performance polyurethane rear end housing bushings are made with a high durometer material, meaning they're quite firm. This firmness is key because they replace the original rubber bushings found in many 1978-1996 GM B-Body cars, like the Chevrolet Caprice or Buick Roadmaster. Over time, those factory rubber bushings can get hard, crack, or even turn to dust, which really hurts how your car handles and rides. By swapping them out for these polyurethane units, you're getting a more solid connection between your rear axle and the car's frame.

What this means for you is a noticeable improvement in how the car feels, whether you're just cruising around town or pushing it a bit harder on the track. The kit comes with two bushings and two washers that help keep everything aligned and prevent side-to-side movement, so you won't have to worry about the bushings shifting out of place. Plus, polyurethane is much more resistant to things like weather, UV rays, and general abuse than rubber, so these should last a good long while. They're made right here in the USA, too.
