2-1/2in Carb Studs

The 2-1/2in Carb Studs from MOROSO (MPN 37960) are precision-engineered fasteners designed for carburetor mounting and fuel system assembly in performance and street engine builds. Available as a set of four, these studs serve as the critical connection points between your carburetor and intake manifold, ensuring proper alignment, repeatability, and secure hold under varying engine loads and vibration. Whether you're upgrading a classic muscle car, restoring a vintage hot rod, or fine-tuning a fuel-injected conversion, quality carburetor studs are non-negotiable foundation components that prevent leaks, misalignment, and catastrophic intake gasket failure.

These 2-1/2 inch studs feature a distinctive bullet-nose design that simplifies installation and reduces potential for cross-threading during assembly. Manufactured from hardened steel and finished with zinc oxide plating, the studs resist corrosion and thermal cycling while maintaining dimensional stability across repeated engine warm-up and cool-down cycles. The dual-thread configuration—available in both 5/16-18 and 5/16-24 pitch—accommodates a wide variety of intake manifold and carburetor specifications, making these studs versatile across multiple engine platforms. The zinc oxide coating protects against rust and oxidation without compromising the structural integrity required for secure fastening in high-vibration engine compartments.

These carb studs are ideal for rebuilding vintage carburetors, performing intake manifold gasket replacements, or installing new carburetor setups on street and racing engines. Mechanics and engine builders benefit from the precision bullet-nose design, which reduces installation time and improves alignment repeatability across full rebuilds. The four-stud set covers complete carburetor mounting on most small-block and mid-block engines, and the compact 3.75 x 1 x 5 inch package makes storage and transport straightforward. For any serious carburetor work—whether OEM restoration or performance upgrade—these MOROSO studs deliver the durability and precision finish expected from a trusted manufacturer in the automotive aftermarket community.
