If you're looking to boost your hot street car or racing vehicle, the Holley Double Pumper® carburetors are a fantastic choice. These carburetors have become synonymous with performance, tracing their roots back to the muscle cars of yesteryear and powering countless vehicles to victory on the track.

The Ultra Double Pumper™ Carburetors are made entirely from aluminum and feature metering blocks and a base plate crafted from 6061-T6 billet aluminum. They weigh about 5 lbs. less than comparable zinc carburetors, which is a significant advantage.

With an optimized fuel curve for peak performance, the new Ultra Double Pumper Carburetors come packed with features. You’ll find aluminum construction, anodized billet aluminum metering blocks and base plate, four-corner idle for precise control, dual accelerator pumps for extra fuel during those initial bursts of speed, and mechanical secondaries for impressive performance. The clear fuel level sight plugs make adjusting fuel levels a breeze, and there's even a Ford automatic transmission kickdown for compatibility with popular Ford transmissions. Plus, for the first time on a Double Pumper, enjoy a factory pre-set electric choke that makes cold starts quick and easy.

The polished finish combined with the striking black metering blocks and throttle body will ensure your ride stands out, whether you're at a car show or tearing up the track.
