Urethane Knobby Spring Plate Bushings, pair 2" - See Chart

The soft stock spring plate bushings can cause the rear to feel "squishy" and cause poor control and wheel hop. Upgrading to urethane grommets will help provide a better ride and more positive handling.  It is a "must" when upgrading to adjustable spring plates, as they can be ordered in sizes that are different than stock. Sold in pairs.

Here's a chart to help you get the correct size:
