My son has a 1988 full size Blazer. We just installed 4" superlift kit. Springs in front, blocks in the rear. It went together farely decient. I didn't change the pitman or steering arm. At about 30 - 40 mph the front end goes into a very bad wabble. Is it because of the angle of the steering arm?

 

Could be the angle coupled with worn components.. Have you contacted superlift with your concern? Their support is pretty good!

 

Not yet. I have to call them anyway because they sent me the wrong shocks. Looking into other forums thier calling this a "Death Wabble".

 

Yeah, you might need to get a drop pitman arm to solve the problem.
