1 3/8In Carb Stud Kit

The Racing Power Co-Packaged 1 3/8" Carb Stud Kit is a purpose-built fastener set designed for carburetor mounting applications on high-performance engines. This four-piece kit delivers the exact studs and hardware required for secure, vibration-resistant carburetor installation on street, strip, and competition builds where reliable fuel delivery depends on solid mechanical connections.

Each stud measures 1.375 inches in length and features dual thread specifications: 5/16-18 and 5/16-24 UNC/UNF compatibility, allowing flexibility across different carburetor flange and intake manifold configurations. The zinc oxide finish provides corrosion resistance in engine bay environments while maintaining clean, attractive appearance. Steel construction delivers the hardness necessary to withstand mounting torque cycles without stripping or deformation, critical for carburetors that experience thermal expansion and vibration stress during continuous operation.

This kit addresses a common pain point for engine builders: sourcing matched hardware that prevents carburetor movement, fuel line vibration damage, and uneven needle seating. Whether restoring a classic muscle car, upgrading a hot rod intake, or replacing worn fasteners on a performance carbureted engine, having dedicated carburetor studs on hand eliminates improvisation with undersized or mismatched fasteners. The included hex nuts ensure repeatable, consistent torque values across the mounting surface.

Racing Power Co-Packaged is recognized within the performance automotive industry for producing fastener kits engineered to OEM and competition specifications. This carburetor stud kit is compact and lightweight—0.18 lbs—making it ideal for shop shelves, restoration projects, or emergency replacements at the track or dyno.
