Plus you have that small block which maybe a zero rate for a shackle flip. It doesnt look to be tappered. If its a zero rate it needs to stay. Your spring pack isnt stock by anymeans. And a pic when you started this thread would of been better instead of guessing.

 

Oops sorry meant Ubolt not Ujoint. It rides really stiff in the rear figured that was the rancho shocks. So then those blocks are stock height?

 

those are stock blocks. Your lift looks to be coming from the extra leaves in the rear springs. Probbly that extra little block above the 3 inch stock one.

 

SOLUTION: get stock springs from any 1500 in the junkyard.
