i towed my comanche home on a flatbed trailer with an 88 xj 4,0 aw4 on 35s with 456 gears fully locked drove 65mph about 90%of the time and could stop like no tomorrow. no trailer brakes eather. but had bb upgrade and 8.8 used ebc yellow stop on rear and their quick stops on the front. i could lock them up. but I'm in florida its kinda flat here so easier to tow.
