Ok so a buddy and I set out to install my new trail gear 5" rear springs to rid myself of my tired stock springs with 5" blocks <img src="/forums/images/graemlins/barf.gif" alt="" /> (hate blocks).... Sooo following the instructions I measured and remeasured the front spring hanger for 6" forward marked the location and proceded to cut the stock spring hanger off and then welded the new in place... Same for the rear.. I placed the rear shackle hanger 2" back from stock per the instructions... Bolted up the spring and put the weight of the truck on it shackle angle looked to be about 30 degrees (just like the instructions said it would..).. So we thought we were good bolted everything back up and got it rolling again.. Shackle angle was still about 30 degrees... Here is the problem. I jumped up in the bed and heard a clunck.. The shackles were now touching the rear of the frame!!! (towards the rear) and were stuck there!! It took both of us to pop the springs back into position.. and there they sat at 30 degrees again... So whats the deal??? I'm fairly new to toyos... Do I need longer shackles? move the rear shackle mount furher back?? Is this a common problem?? Thanks -Brian
