I had an ishock and applied springs up front. Like it alot. The stiff springs should do you fine. But remember, they are only springs. I just installed some BBR forks and with the ishock.. it is a world of diff. I would definitly get the ishock, you can use it with the stiff springs with no problem. Mine is the one w/o the res and it is a 250lb spring attached to a five 0 swingarm
