9/16 x 7/8 spring bushes and a 5/8 or 16mm bush for the centre pin.

Shackle plates are generally placed on the rear of each spring however this rocker requires shackle plates to be attached to the rear of the front spring and the rear of the back spring.

To accurately locate the front and back holders follow these instructions.

Locate your centre hanger

Measure the spring from the centre of eye to the centre of the eye. Example, 710mm
Measure from the rocker eye and add (spring length) 710mm then add 25mm and clamp the hanger into position
Repeat the process for front and back hangers
The loop part of the spring points towards the rear of the trailer.
