Differential side adjusting ring kit.
The rings themselves have been machined from HE15 Alloy, which have a lot bigger surface area on the bearing face, and are a little thicker than the other alloy ones that used to be on the market. They are half the weight of the original steel versions, and have been anodised in black. These now come with stainless steel clips, mounting bolts and washers to fit directly into your existing differential.
Will fit the English differential, used in many applications.
Machined here at Kelvedon Lotus Limited, Lincolnshire, England.
