Ok I'm still on a stock rearend in my 2000rcsb, suspension is bone stock save for 2in lowering shackles, I decided to order some 28x11.5 m/t for the stock wheels. I decide to go out for some testing on the street, only my second time out with them. They feel great and have cured the spinning for now, however I decided to slow it down and try them from a dig, I come off idle to about 2/3 throttle as soon as I'm moving I hit WOT, there wasnt any perceivable spin just launched hard, felt great. Problem starts when I get home and notice the truck is twisted to the left, the right wheel well is sitting just over 2in higher than the right side, I notice fresh scrapes from the overload springs contacting the leaf pack. Then I get down and look at them and both of the overloads are tweaked about 2 degrees pointing to the right ( looking from behind). Could this be an effect from the stock shock locations, one fore and one aft?? My plan is to loosen the U bolts tomorrow and try to get it sitting right again, only thing I can think is there is some nasty axle wrap going on that tweaked something in the rear suspension, any ideas? This happen to anyone else?
