ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Fortify the foundation of your legendary Mopar 426 Hemi engine with the Auto Racing Products (ARP) BBM Main Stud Kit. Specifically designed for 2-bolt main applications, this hex nut main stud kit provides superior main cap clamping force, crucial for preventing cap walk and crankshaft deflection under extreme loads. Essential for any high-performance or racing Hemi build, these studs ensure your bottom end can handle serious horsepower.
Each main stud is meticulously crafted from ARP's premium chromoly steel, a material renowned for its exceptional tensile strength and fatigue resistance. The studs undergo a proprietary heat-treating process to optimize their metallurgical properties, followed by precision thread rolling for enhanced fatigue life. A robust black oxide finish not only provides excellent corrosion protection but also gives a professional, race-ready appearance to your engine's core.
Auto Racing Products is the global leader in high-performance fasteners, and their main stud kits are a cornerstone of engine reliability. Main studs offer a significant advantage over traditional main bolts by providing more consistent and accurate torque readings, reducing distortion of the main bearing bores. This results in a more stable and durable bottom end, critical for maintaining proper bearing clearances and extending engine life. Trust ARP to deliver the strength and precision your Mopar 426 Hemi demands.
