Polyurethane bushes are popular because they are self-lubricating and hard-wearing. As a precautionary measure, replace shackle bolts when replacing bushes.

Vibration fatigue causes wear on bushes, shackle bolts and shackle plates.

Check your shackle bolts for wear during your pre-trip inspections.

TIP: Replacing your old bush is easy. Place the new bush on top of the old bush and knock the new bush in with a hammer.

All of your bushes, bolts and shackle plates are easy to replace, providing you with the right parts. These trailer parts can be challenging to locate; however, Couplemate now manufactures its spring bushes.

Sometimes, owners wish to insert steel bushes and switch to a greaseable shackle system. New hardened steel bushes are available from our Couplemate retail store.
