    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, or Black) allow for a personalized look while maintaining the ultra-high strength and durability you get from billet. They weigh in at approximately 5 lbs. less than a comparable zinc carburetor.

    The Ultra Street Avenger carburetors have the same great features as their aluminum counterparts such as a tumble polished aluminum finish main body and fuel bowls. The Hard Core Gray finish Ultra Street Avenger features a hard coat anodized main body and fuel bowls for ultimate corrosion resistance and only available with black anodized billet aluminum metering blocks/base plate. Other features such as quick change vacuum secondaries for easy tuning to optimize performance or fuel economy; four vacuum ports for all necessary vacuum accessories; factory preset ''No Trouble'' electric choke for easy startups; built-in fuel filters; and an included fuel line kit. 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. The clean, polished look coupled with Red, Blue, or Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track.
