Whether you're a weekend mechanic reviving a classic engine or a restoration specialist returning a fuel system to original specifications, this kit contains all the precision components needed to rebuild your carb without trial-and-error sourcing. Designed specifically for gas-fueled applications, it ensures your carburetor functions at peak efficiency and reliability.

This rebuild kit includes all internal wear items and sealing components—gaskets, needles, seats, springs, and jets—engineered to OEM tolerances by Holley, the industry standard for performance carburetors. The fast-kit design means every component is matched and tested, eliminating guesswork during reassembly. Compact and lightweight at just 0.35 pounds, the kit contains all the small but critical parts that deteriorate over time due to fuel varnish, ethanol exposure, and normal wear. Proper rebuilding restores fuel atomization, idle stability, and throttle response that age and contamination degrade.

Mechanics and engine builders working with classic muscle cars, hot rods, and vintage street machines rely on this kit to service the legendary Holley 2300 Ultra XP platform. Installation requires basic carburetor knowledge and standard hand tools; thorough cleaning of the carb body before assembly is essential for success. This rebuild kit is the cost-effective alternative to carburetor replacement and is compatible with all Holley 2300 Ultra XP models running gasoline fuel systems.
