Polyurethane Leaf Spring Bush from 45mm to 60mm

Polyurethane leaf spring bush is suitable for most springs with a width of 45mm and 60mm, including galvanised boat trailer slipper springs. Couplemate bushes are a precision fit.

It can be challenging to find a good nylon bush. As a result, Couplemate now manufactures high-quality polyurethane leaf spring bushes to its precise specifications.

  1. It is a good fit both externally and internally.
  2. The material should not chatter or chip upon insertion.
  3. Shackle bolts should not be loose inside a nylon bush. Purchase new spare parts here.
  4. Your bush should be a tight fit inside your spring.

Australian made campaign45mm Polyurethane Spring Bush is available in the following sizes

  • 1/2 x 7/8 x 45mm
  • 9/16 x 7/8 x 45mm
  • 9/16 x 3/4 x 45mm
  • 5/8 x 7/8 x 45mm
  • 1/2 x 3/4 x 45mm
  • 5/8 x 7/8 x 60mm

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.

Finally, spring bushes, shackle bolts, and plates that fit 45mm wide springs are all subject to vibration fatigue.
