Shackle Spring Center Bolt – 75mm x 8mm

Spring centre bolt is high tensile and 75mm x 8mm to suit most slipper, shackle and tandem leaf spring sets. Replacement bolt for your spring.

Standard spring centre bolts are mild steel bolts and are tightened by the manufacturer during the manufacturing process.

When attempting to re-use the spring centre bolt, it is often the nut will strip its thread. This replacement tensile bolt is the ideal replacement.

Caravan Spring Choices


  • 13mm head diameter
  • 10mm head thickness

  • 8mm thread thickness
  • High Tensile bolt and nut
  • Slotted top so the bolt can be tensioned.

This is a replacement high tensile bolt used when removing a leaf spring or re-tension your shackle spring.

We do not recommend adding old leave springs to existing spring packs. All springs suffer fatigue over time therefore they are unsuitable to start a new life in your spring pack.

Alternatively, a new spring leaf is suitable for adding to a spring pack to replace an older broken spring.

Clamp your spring with a G clamp before removing your old spring bolt. Insert the new high tensile bolt then clamp with G clamp.

Once the G clamp is tight then tension this centre bolt.
