Haven't been around ATV's long. What is a hairscramble? If it involves a lot of turns, I would say new tires or something to help handling.

 

Do you have the stock 400ex front shocks still? If so then I would buy some 450r stock shocks. I have them and they are alot smoother and i also race harescrambles.

 

I have a G-Force axle om my banshee and its great. But you would probably want to keep the axle stock width because of trees. I would reccomend hand guards from maybe Madd Dog because I've busted a few fingers on branches before. a pipe would be great for low-end torque which you will need. Don't forget good chest protection.
