45mm Steel Spring Bush to suit Caravan, Camper and Trailer Shackle Springs

45mm steel spring shackle bush is a fantastic replacement where the usage of nylon bushes creates too much wear, and you need to go to a heavier bushing system.

Nylon spring bushes are self-lubricating. Therefore, they do not require greasable shackle pins. Standard pins are suitable for nylon bushes.

Examples of suspensions where steel bushings are suitable are outback springs and tandem rocker arms where the centre bush is 22mm OD. This rocker bush carries half the trailer weight, making it ideal for upgrading.

You will need to upgrade to greaseable shackle bolts when using steel bushes.

  • ID 16mm
  • OD 7/8″ or 22mm
  • Length 41mm and 50mm
  • Suit 45mm wide spring

To install, place the steel bush over the nylon shackle bush and tap with a hammer until the nylon bush is out of the spring.

Spring shackle bushes must be checked regularly and greased when necessary. Removing the shackle pin and examining the hanger and the bolt for wear is also good practice.

Also, inspect the shackle plates and pins attached to the 45mm spring before purchasing your trailer parts.
