How to Measure U bolts (example)

Replacement U Bolt Kit for Jockey Wheel (U3S3)

It is important you retighten u-bolts approx 200lkms after installation due to steels ability to stretch a little under load.

Furthermore, we stress tested these u bolts during manufacture and batch test until destruction.

Destruction loads exceed 17,000kg for 1/2 inch galvanised u bolts.

Finally, our u-bolts are derated to 375kg each or 1500kg per set of 4 or enough u-bolts to suit a single axle.

The max rating of 750kg axles is 750kg with u-bolt rating @ 1500kg.

The humble u-bolt is a major cause of caravan accidents? We think so, read here.
