Im selling my 4000 stall. it works great. Has less about 100 miles on it. and about 15-20 passes. Im going with a A3 and a brake. It started out as a TCI 3500 As soon as I got it I send it to my own guy. He cut it open changed the stator, pump, and the fin angles. Also put a new hub on it. and balanced it. Asking $550.00 shipped. warrantied for 1 year. It stalls great. Will consider trade on body mounted Torque arm or some qa1s

I also just installed a ford 9 inch. Im selling my old rear. has no more than 100 miles on it sience it was rebuild. Motive 3.73 gears torsen posi unit. Minus backing plates and brake lines. $400.00.obo Works great. very quit gears.
