Quad. Carb. Bushing

The MR. GASKET Quad Carburetor Bushing (Part #1512) is a precision throttle lever stud designed for 1/4-inch throttle rod applications. This aluminum and steel component delivers reliable mechanical linkage performance in high-performance and marine engine configurations where smooth, responsive throttle actuation is critical to engine control and operational safety.

The dual-material construction—aluminum body with steel reinforcement—balances weight savings against durability under continuous throttle cycling. Chrome and natural finish options accommodate different aesthetic and corrosion-resistance requirements depending on engine bay exposure and salt-air environments common in marine installations. The compact 3.2 x 0.55 x 5.85-inch profile and minimal 0.05-pound weight ensure straightforward installation without adding unnecessary bulk to carburetor linkage assemblies. This stud connects throttle rods to carburetor quadrant levers, transmitting operator input directly to fuel metering without play or deflection.

Performance carb builders, engine tuners, and marine technicians rely on MR. GASKET's throttle control components when OEM bushings wear or when custom throttle linkage routing demands precision hardware. The 1/4-inch rod diameter accommodates standard throttle cable and push-rod systems across multiple carburetor configurations. Whether rebuilding vintage marine engines, upgrading quadrajet linkage, or custom-tuning fuel delivery systems, this bushing provides the mechanical precision needed for repeatable, predictable throttle response without binding or excessive wear.

MR. GASKET's carburetor hardware is recognized throughout the performance and marine engine community for maintaining OEM specifications while offering modern material and finish options. This quad carburetor bushing is sold as a single unit, allowing technicians to replace worn studs individually rather than purchasing full linkage assemblies.
