Brand New 7290 U-Joint Failure

Thanks all, the pinion angle is set up correctly. U joint did not break, just tore up the caps and flange. I will see the car this afternoon and Im betting its those crappy strap clamps that broke. I will change the pinion flange when the pumpkin is rebuilt next week for 1350 and u bolt clamps.
Stock springs? They can rotate quite a bit a 4000 hit, I’ve broke straps that way, they can’t take that amount of rise
