XRAY have introduced two sets of extreme heat resistant diff pins with inserts for the XB8. Available for the large front and rear differentials (3.5 x 26.6 mm) as well as the large center differential (3.5 x 26.6 mm), the precision-ground polished aluminium pins are 30% lighter than steel pins. They come with steel inserts instead of directly mounted in differential case in order to increase lifetime, especially in high temperatures. The diff pins with inserts are available as a pair separately for the front, rear and center differentials.
