Well man, it all depends on your riding style and how much cash you got. I have a lot of fun on my stock front shocks, but not too much fun cause they are really soft for a 200lb rider. Them works shocks are probably a HUGE improvement over the factory ones. If you ride super aggressive or like to jump any at all, I'd say throw a few hundred into getting works shocks rebuilt. Hell, throw them on there. Just cause they are dirty don't mean they are worn out. You might get lucky.
