The Ultra Street Avenger carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061-T6 billet aluminum. Three different anodized color options (Red, Blue, Black, or Hardcore Gray) allow for a personalized look while maintaining the ultra-high strength and durability you get from billet.

Ultra Street Avengers feature the same optimized street calibration as the zinc versions so you know they will run great on your vehicle. In addition, the Ultra Street Avenger now comes with anodized metering blocks and a base plate made from 6061-T6 billet aluminum and a built in, clear fuel level sight glass for easy, no mess fuel level adjustments.
