Quad. Carb. Bushing

The MR. GASKET Quad Carburetor Bushing (Part #1512) is a precision mechanical component designed for carbureted engine builders and performance enthusiasts who demand reliable throttle linkage operation. This bushing serves as a critical interface point in four-barrel carburetor assemblies, where it manages the mechanical connection between the throttle cable, kickdown linkage, and primary/secondary metering rod systems. Whether you're restoring a classic muscle car, tuning a street rod, or maintaining high-performance vintage equipment, a worn or damaged quad carb bushing directly impacts throttle response consistency and fuel mixture control across the RPM range.

The quad carburetor bushing functions as a low-friction bearing surface that allows smooth pivot and linear motion without binding or excessive play in the linkage assembly. MR. GASKET engineered this component to maintain tight tolerances while reducing wear on the carb baseplate and throttle lever arms—critical areas where metal-on-metal friction degrades throttle feel and creates inconsistent air-fuel ratios under load. The compact design (3.2 x 0.55 x 5.85 inches, weighing just 0.05 lbs) ensures it fits within OEM and aftermarket four-barrel mounting points without requiring bracket modification. The material composition provides self-lubrication properties that extend service life compared to older stock components, especially under high-temperature underhood conditions.

Engine builders, restoration specialists, and drag racing teams benefit most from upgrading to this precision bushing, particularly when rebuilding or retuning Holley, Edelbrock, or Demon four-barrel carburetors. Installation is straightforward—remove the old worn bushing, clean the mounting bore, and press or bolt the new unit into place using standard hand tools or a small arbor press. This is an essential replacement during any carburetor rebuild where throttle linkage tolerance stack-up could compromise drivability. For anyone working on classic cars, hot rods, or performance engines where throttle response precision matters, the MR. GASKET Quad Carb Bushing eliminates sloppy linkage and restores factory-like engagement characteristics.
