Up for bid is a good used Super T10 mainshaft to a Dana 18 or 20 6-spline transfer case. I believe this is an Advanced Adapters mainshaft but I am not 100% certain. It has been bead blasted and is ready to use. Overall lenghth is right at 12 1/8 inches. According to my research Advanced Adapters is no longer making these, so if this is the combo you are running you may want to pick up a spare mainshaft. Please do your research before bidding as I DO NOT ACCEPT RETURNS. Thank you and please check out my other items.
