For bars unless you are changing the stem the warrior uses a 7/8 bar.
I had where the height and width felt fine but the sweep angle back is just too much. I wound up with pro taper "raptor bend" and it's the same height and width as stock just with less sweep.
The wrists feel alot more natural now and the bars aren't getting in the space where I'm trying to counterweight on tight turns
Also, yeah an arms for sure. If your stock shocks are still good I'll throw a mention to drw performance for their rear link. That thing made a bigger difference than I expected for the rear suspension
