Brought from our Pro-Part division to life by members of the Bulltear.com forum and Pirate4x4.com forum. This adaptor replaces the stock TH400-dana20 adaptor found in jeeps 67-74'. Rock 9 allows the Dana 20 to be clocked at stock position and at a flat clocking position to allow for increased clearance. We also put healthy grooves for silicone sealant between adaptor and transmission/T-case. Every aspect of this adaptor has been beefed up making it the strongest adaptor ever for its application. Milled from a soilid block of 6061 Aluminum. Adaptor comes with new seals and a new bearing. $435 shipped
