Carburetor Stud Kit 5/16 x 1.250/1.700 OAL

The Carburetor Stud Kit 5/16 x 1.250/1.700 OAL provides a critical upgrade for any performance intake system where consistent clamping force is required to prevent vacuum leaks. In high-performance automotive applications, the interface between the carburetor base and the intake manifold is a common failure point if standard hardware is used. These ARP fasteners ensure the base gasket is compressed evenly across the entire mounting flange, maintaining a reliable seal under high-vacuum conditions.

Engineered from high-strength chromoly steel, this kit features a dual-thread design including 5/16-18 for the manifold side and 5/16-24 for the nut side. The use of chromoly is essential for mechanics who demand higher tensile strength than what standard grade 5 or grade 8 hardware offers. The black oxide finish provides a professional appearance and a layer of protection against the harsh environment of an engine bay, helping the threads survive repeated heat cycles and adjustments.

Experienced builders often prefer a stud kit over traditional bolts because studs allow for more accurate torque loading and protect the delicate threads in aluminum intake manifolds. By threading the stud into the manifold first, you eliminate the friction of the fastener turning against the aluminum during final tightening. The 1.250 and 1.700 inch lengths are specifically selected to accommodate various spacer and base plate combinations found in custom fuel system configurations.

Reviewing the technical specifications of the ARP 200-2409 reveals a comprehensive set of eight studs complete with matching hex nuts, providing enough hardware for complex dual-quad setups or multiple single-carburetor builds. For those looking to buy a reliable mounting solution that minimizes the risk of flange distortion, this kit is the industry standard. This hardware set is for sale for automotive enthusiasts who prioritize precision and long-term durability in their vehicle modifications.
