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

'69 to '79 IRS Type 1 and 3: 2" knobby inner, 1-7/8" round outer

'61 to '68 Swing Axle Type 1 and 3: 2" knobby inner, 1-7/8" knobby outer
