5/8″ Heavy Duty U-bolts suited to caravans and trailers over 1500kg

5/8″ Heavy Duty U-bolts suited to caravans and trailers over 1500kg. U-bolts over 1500kg need to withstand greater shock loadings.

Heavy duty hardware is ideal for trailers over 3t and up to 4.5t ATM.

Re-tightening u-bolts

Re-tightened after 300 kilometres from installation.

Loose u-bolts cause problems. These problems include

  • Spring slippage off the axle.
  • Moving axles backwards of the spring centre.
  • Broken springs.
  • Brake cable and wiring damage.
  • Excess tyre wear.
  • Axle separation from the trailer.
  • Damage to caravan skirts.
  • Damage to water and sullage tanks.

Loose u-bolts are a major cause of caravan accidents therefore, we recommend re-tightening.
