If you are complaining about the front shocks already, you could do the DS450 mod. The sway bar is nice, but only downfall I have is it takes the comfort away from the quad. There is still some comfort there, you may not notice if you've been riding SRA for ever, but if you ride with the stock sway bar for a while and switch to that, you'll notice it is a little rougher. But it makes up for it in cornering. Other than that, what the others recommended. Basically what you'd do to the 450, can do to this. Big 3 for more power, different tires, cheap suspension like the ds450, or if money is no issue then better suspension like Fox or MOtowoz.
