ATM Innovation XRB-850AN XRB Series Gas Annular Carburetor, 850cfm

ATM Innovation’s XRB is a step up from its XRC series. While it shares many of the same features with the XRC, the XRB is intended for racers that frequently take apart their carburetors for precise tuning changes – the billet metering blocks add another level of durability over die cast components. The billet throttle bodies are stronger and more precise too. Plus there is more detail work like “slabbed” throttle shafts that promote smoother flow and less turbulence.
