These third member housings are made from billet 6061 aluminum. All third members come with a billet pinion support, 7075 aluminum main bearing caps, carrier adjusters, replaceable pinion support and load bolt. This billet case has added material in weak points of the stock casting making this stronger than the original housing. This is the perfect part to replace that tired, twisted heavy cast housing.

This item is proudly designed, engineered, and manufactured in house at IMS.
