This is a brand new Speedmaster third member for a ford 9 inch rear end with 31 spline axles . The gear ratio is 3.70:1. This unit is brand new and has been installed in a rear end with oil for the last four years. It (the truck) has been moved in and out of the garage a few times the 3rd member has 0 miles. It has a very small residual leak from the input shaft I believe. It is still installed in the truck so I will need 24-48 hour notice before I can remove it. This is priced firm at 1,100.00 cash only. This will cost you almost $1500 to buy New from jegs or Summit. I'm not in a rush to get rid of it and I don't need the money so no trades and no offers. I am running a different Engine than originally planned and transmission so I need a longer gear set . $1,100.00 FIRM, thanks!
