Suits standard tandem 60mm eye to eye with nylon bushes or shackle springs with steel bushes (Al-ko Outback rebound Series.)

5/8 = 16mm approximately.

16mm x 100mm Greaseable Shackle Bolt suit a variety of leaf springs where a situation of metal on metal exists. Example, rocker springs and outback springs have a metal roller or bush that requires a greaseable shackle bolt.

Non-greaseable bolts fit inside a self-lubricating nylon bush and do not need grease. If you springs have nylon bushes, it is not advisable to change your shackle bolts to greaseable.

The knurl under the head has a particular purpose. The knurl locks into the shackle plate to help prevent the bolt from spinning during spring compressions. Broken welds are a good sign the bolts need replacement.

On standard tandem and outback springs, the knurl is welded onto the shackle plate to stop the bolt from turning. A rotating bolt in the shackle plate, wear significantly increases.

How to tighten shackle bolts.

  • Tighten 16mm x 100mm greaseable shackle bolt until home.
  • Back off 1/4 turn.
  • You need a small space between your shackle plates and spring otherwise you will develop an annoying squeak.
  • This squeak is due to no tolerance between shackle plates and spring.
