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, managing the mechanical connection between the throttle cable and kickdown linkage. 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 can directly impact throttle response consistency and fuel mixture control.

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 can degrade throttle feel and create 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.

Engine builders and restoration specialists will benefit from this bushing, as it enhances the performance of carbureted systems. Its design is compatible with popular carburetor brands like Holley, Edelbrock, and Demon, making it a versatile choice for various applications. By replacing worn bushings with the MR. GASKET Quad Carburetor Bushing, you can ensure improved throttle response and better fuel mixture control across the RPM range.
