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.

TIP: Our most common call for help is wrong spring picked for tandem trailers. Tandem trailers usually have offset springs.
Install electric brakes on both axles over 2000kg.
