will these fit my quad

the hubs should, the axle nut might, the rezzi cover will work if you have front hydros. the throttle cover might.
if you have rear hydros the brake lever might work. not sure what the other two things are.
 
the other 2 things are the heelgaurd brakets and will not work, you have to fab new ones when using yfz heelies, and as stated above the covers will work if you have hydro fonts, in my brake building experience, nothing but blaster pedals will work with our pegs
the shifter may bolt on, but looks to be curved out too much
the front hubs will if you have front hydros
 
oh, my bad, then they'll definately fit our axle, so you can jump to the 9" warrior/banshee/yfz rims, but do not fit our rims
