How to Install

Where possible, Couplemate™ recommends flipping your chassis upside down to install the kit. Installation time ranges from 1-2 hours and requires welding.

1. Locate the wheel’s centre well because this is where the spring centre pin is located.
2. Measure from the centre pin to the front of the shackle.
3. Use this measurement to clamp the front bracket into position from the centre of the wheel well.
4. Obtain the rear hanger (dumbjack) measurement from the length of the spring from the centre of the eye plus 25mm for 710mm springs.
5. This length will be 735mm from the front mount.
6. Weld both hangers into position.
7. Install the front shackle bolt and spring into the hanger.
8. Connect rear shackle plates and shackle bolts into the rear of the spring.
9. No Load: Shackleplates should be facing towards the front of the trailer.
10. Total Load: Shackle plates will swing to the rear of the chassis.
