when you did this, you said you put the factory block back, does this mean you took off your u-bolts? if so check and make sure they are tightened properly, from what i have heard and having done this myself, there is very little sway involved after doing thisdodge ram man said:
also, it says you have a 4 inch lift, and the factory block along with the shackle flip, so if i am reading this right you have over 8 inches of lift in back, is this right?
if so just having that much lift in the rear may be part of the problem
