Air Cleaner Stud Kit - 1/4 x 3.200 S/S

The Air Cleaner Stud Kit - 1/4 x 3.200 S/S (ARP 400-0306) is a precision fastening solution designed for builders and mechanics who demand reliability in high-vibration engine bay environments. Air cleaner assemblies experience constant thermal cycling and vibration, making quality studs essential for maintaining secure mounting. This stainless steel stud kit addresses a critical need in custom engine builds, restorations, and performance modifications where OEM fasteners fall short of durability standards.

Manufactured by ARP—a leader in fastener engineering for automotive applications—these studs feature 1/4-20 thread pitch and a 3.2-inch length, making them compatible with most carburetor and fuel injection air cleaner housings. The polished stainless steel construction resists corrosion, vibration loosening, and thermal stress while delivering a professional appearance under the hood. Stainless steel's superior strength-to-weight ratio and fatigue resistance ensure these studs maintain clamp load across repeated heat cycles, preventing the air cleaner assembly from shifting or separating during aggressive acceleration or high-RPM operation.

Mechanics and engine builders working on vintage muscle cars, street rods, and modern performance platforms benefit from this kit's reliability and clean appearance. Installation is straightforward—simply thread the 1/4-20 studs into existing air cleaner mounting points and secure with the included hex nut. Whether you're restoring a classic engine, upgrading a street machine, or building a show-quality power plant, these studs eliminate the risk of loose fasteners compromising air filter sealing or engine bay aesthetics. Compatible with most carburetor-style and fuel injection air cleaners that accept 1/4-inch studs.
