The 16mm 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 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 bolt 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 a shackle bolt.

  • 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.
