you want your shocks to be soft and it will help.i dont know about yours but on my buggy the shocks are not mounted in the right place to work right.when the shock is fully compressed the a-arm should be at a 90 degree angel with the shock.this will let it move without binding.if its at more than a 90 it will not work as well and the farther from 90 degrees the less it works.
