Introducing the greatest thing to happen to off-road trucks since four-wheel drive: the Holley Truck Avenger carburetor!

The award-winning Holley Truck Avenger carburetor is the first carburetor designed from the "flange-up" as an off-road carburetor. No other carburetor comes close to the Truck Avenger's ability to offer peak performance at extreme vehicle attitudes over rough terrain, and lightning-quick stump-pulling low speed response for towing and mud-bogging.


  • Precision engineered by Holley specifically for the demands of the truck enthusiast.
  • Exclusive New "No Trouble" metering block eliminates fuel spillover through the boosters at extreme angles. Flood-free operation up to 40 degrees while climbing and 30 degrees during side hill maneuvers and "nose down" descents. This allows you to off-road in confidence with out the annoying hesitations, stalling and flooding typically associated with carbs in an off road environment.
  • New Annular Boosters provide incredible low and mid range throttle response and torque.
  • Exclusive dichromate finish is built for durability and good looks without the maintenance of a polished carb.
  • Externally adjustable, "No Trouble" spring loaded needle and seats promote stable fuel levels for improved fuel control under all conditions.
  • Square fuel bowls provide precise fuel control and maintain classic Holley look.
  • Single fuel inlet banjo fitting for "Bolt on and Go" simplicity.
  • New Viton fuel transfer tube seals ensure leak proof operation.
  • Exclusive New "No Trouble" one-piece vent tube eliminates fuel spillover from the vent tubes during extreme maneuvers and lends a tough performance appearance to the carb.
    Includes clear sight plugs for easy float setting, quick-change vacuum secondary cap and electric choke for "No Trouble" operation.
  • Four vacuum ports included for easy accessory hookup.
  • Designed for the off-road enthusiast but works equally well in street truck applications.
  • Packaged in attractive New Truck Avenger box to complement existing Street Avenger styled packaging for easy plan-o-gram layout.
