While that maybe true, it sure worked for me.

Alright; for those who want info on "4 inch shackles". My truck is an 02 with Eibach coils up front and JL 2~3~4 shackles out back. With the bolt in the top hole I get 32 1/2 out back and 32 1/4 up front. It sits perfect with just a slight rake As for wandering axle feel; I have a panhard bar from ruslow, so it is not a problem.

My opinion; they are a great, quality product! Thanks JL

 

Also, Pinon angle looks great. And the truck currently has 7000 miles on it, and no rear hitch. An the hitch and it will drop another 1/4 or so.

 

I just put my STOCK shackles back on with the ROUSH
kit and I am very happy with the new geometry. The
lever distance on even my 2" shackles is a bit more than
I would like to have back there, hence going back to stock.

Road courses are brutal on suspensions ...
