Ok, I have searched and searched and I am still at a loss. I just did the J spring lift all around with Mr Gasket up front. My question is, the load sensing proportioning valve..............I am confused, do I adjust it up, or lower it? Like I said, I read tons of stuff but then I just started getting confused over what to do. If anyone has some constructive help please post it up. thanks oh ya, not sure it matters but its a 1993 fzj80 and I am getting ready to put on the 315s.
