Mastodon Carburetor Studs Kit 5/16" X 2 1/2"

Set of 4 carburetor mounting studs in 5/16" thread, 2-1/2" length. The right hardware for square-bore carburetors (Holley, Edelbrock, Quick Fuel, Demon, Brawler) on standard 4150-style intake manifolds. Studs prevent stripped-out threads in cast aluminum manifolds, hold the gasket flat during install, and let the carb drop straight onto its mounting position without juggling alignment.

Includes 4 studs with matching nuts and washers.

• Quantity: 4 studs + 4 nuts + 4 washers
• Compatible carbs: Holley 4150 / 4160 Double Pumper, Edelbrock Performer / AVS, Quick Fuel, Demon, Brawler — any 4150-style square-bore
