This is the large cam gear which goes over the brake shaft on the Warn M8274 high mount winch.
The GP large cam gear is precision cut from EN36. The re-design of the cam gear allows more positive engagement & meshing.
We have a range of parts in our online store to suit the Warn High Mount M8274 winch, if there is something you cant find, please contact us and we can get it in for you.
