45mm Dumbjack Rear Spring Hanger

45mm Dumbjack Rear Spring Hanger

The 45mm wide dumbjack spring hanger is an essential component of a single axle and a tandem axle eye to eye suspension systems.

The front eye of a shackle spring is connected to a fixed hanger instead of the rear hanger that has shackle plates attached.

The rear shackle plates connect to the dumbjack via a shackle bolt.

Spring movement is towards the rear. Shackle plates swing backward to compensate for undulations in the road.

We do not supply a dumbjack with a bush. Bush sizes are 22mm OD and either 1/2″, 9/16″ or 5/8″ ID.
