that even make sense?
Ive been in SC 2nd gen and that's def not normal. When you get on it, it gets going. Unless your leafs cant handle the power. Im thinking axel wrap/wheel hop is the issue here. Traction bars will do wonders for you im guessing .


And Procomp uses lift blocks in a lot of their kits. Blocks make it worse.

Its hard to explain but do a search on Youtube and you can find plenty of vids that illustrate this very well.


Lift blocks tend to aggravate the symptoms even more.
i sent my valve body off to level 10 to be modified… is it possible it could be the valve body not working properly causing my surges and whatnot? almost like its getting caught between gears. valves not opening and closing at the proper moments? i might be talking outta my ass, but i gotta figure out what the hells going on...
