hey everyone

I just changed the stock carriers to the rpm ones with the 5x11 bearings. My question is. the origanal ones had a little washer up against the origanal 5x8 bearings on each side. these seemed way to small for the 5x11s so i left them off
do i need to get bigger washers or whatever thoes things are called or not?
its on an e-pede

Thanks
