My BL muggy conv.

[roweder]

I use the stock plastic bodies and the stock muggy shafts, the longer shafts can break because they slam into the shock cap when it bottoms out, and i haven't had any problems with the seals, i use 30wt oil in the front and 25wt in the back and black 6.0 springs and it runs great. The problems you are having could be caused by the integy shocks because they are longer and are made for the LST2 which uses longer shocks, so the shocks will bottom out before the truck does.
