With the Blackout bearings from Atlas Truck Co. you get bearings that is as ready as can be for shredding. Prelubricated and with built-in spacers. Fewer pars mean a more steady setup with a very tight compression around the bearings.
Though it is a lot more tight it spreads out the load much better than regular wheel-setups - Thanks to the flare in the spacers.
With ABEC9 precission you get the speed you need for doing downhill bombing runs.
