The bush must be 59mm wide with an ID of 16mm. (known as a 60mm bush).
60mm rocker roller spring made by Al-ko and other manufacturers all use a 60mm bush.
We no longer sell plastic rocker roller bushes due to load failure in many cases. Use this bush to replace plastic 60mm roller bushes.
The metal bush carries loads up to 1125kg for 4.5t suspension systems.
When installed correctly this 60mm bush must roll freely between the front and back of the rocker spring eyelet.
Some installers like to install hangers on a piece of angle iron (see photo below).
