Prothane 73-81 Ford F100/150 Rear Frame Shackle Bushings - Black

These black polyurethane bushings from Prothane are made for the rear frame shackles on your 1973-1981 Ford F100 or F150. Polyurethane is a well-known material for suspension components because it's more durable than rubber and offers a firmer ride. When your original bushings wear out, you'll notice sagging in the rear and a less responsive feel from your suspension, especially over bumps or when carrying a load.

Prothane uses a proprietary blend of polyurethane that's designed to hold up to the stresses of daily driving and hauling. This kit replaces the stock rubber bushings, which can crack and degrade over time. Installing these will help restore the intended geometry of your rear suspension, leading to a more stable and predictable ride. They fit right into the factory shackle locations, making them a straightforward replacement for worn-out parts.
