okay so I bought a ds450xc, and I need it to be mx ready but the aarms are 1100$ the ones I want so this guy is selling a brand new set of mx aarms which from can am are true long travel aarms for 350$, when I change the aarms is there anything speical I have to do, and what about the ball joints and all that how do i set that up. As for shocks im not looking to speed much but what would be a nice upgrade over my stock 450 fronts for the long travel aarms. should I also get a stock mx rear axle, or buy aftermarket?
