Whether you're crawling over rocks, powering through mud, or cruising the backroads, this carburetor delivers rock-solid performance in the toughest conditions.

The Holley Truck Avenger features off-road-calibrated metering blocks, a built-in fuel bowl vent baffle, and a spring-loaded needle and seat to prevent fuel slosh and stalling during steep inclines or side-hill angles.

Rated at 670 CFM, the popular Holley 670 Truck Avenger model is ideal for small- to mid-block V8 engines, providing a great balance of throttle response and fuel efficiency.

Easy to tune and install, Holley's design ensures reliable power and drivability whether you're running a rock crawler, weekend wheeler, or lifted daily driver. Zinc-coated for corrosion resistance, this carb is built to endure harsh elements and long hauls.

If you need a carburetor that works as hard as your truck, the Holley Truck Avenger is the performance upgrade you can count on. Trusted by off-roaders and performance enthusiasts alike, it's the perfect mix of rugged durability and Holley precision.
