45mm Shackle eye to eye spring

Enable load sharing by linking the 45mm Shackle through a “rocker” assembly. Load transfers from one axle that is carrying a significant percentage of the weight (crossing kerbs, etc.) to the other axle.
The rear end of the spring is connected to a dumjack whereas the front of the spring is connected to a spring hanger. Shackle plates are used in conjunction with shackle bolts to connected the spring to the dumb jack.
Eye to Eye Shackle Springs are rated as follows
- Three leaf – 425kg
- Four leaf – 550kg
- Five leaf – 650kg
- Six leaf- 750kg
- Eight leaf – 850kg
TIP: Our most common call for help is wrong spring picked for tandem trailers. Tandem trailers usually have offset springs.
Trailers rated between 750kg and 200kg must be braked on one axle.
Install electric brakes on both axles over 2000kg.
