BBC Main Stud Kit - Fits 2-Bolt- No Windage Tray

The BBC Main Stud Kit – Fits 2-Bolt is a heavy-duty engine fastener assembly engineered for Big Block Chevy platforms requiring a robust, corrosion-resistant main stud solution. Built for builders, engine shops, and performance enthusiasts who demand reliability under extreme combustion pressures, this 2-bolt main kit replaces factory hardware with precision-engineered studs that maintain clamp load integrity across repeated heat cycles. The absence of a windage tray design delivers maximum flow efficiency for high-RPM applications where internal clearance and oil circulation are critical.

Manufactured from chromoly steel and finished in black oxide, the BBC Main Stud Kit provides superior strength-to-weight characteristics compared to standard cast-iron fasteners while resisting rust and corrosion in demanding engine bay environments. Hex nuts deliver secure, repeatable fastening torque without slippage, and the chromoly construction maintains dimensional stability even under peak cylinder pressures and thermal stress. The black oxide coating not only protects against oxidation but also reduces galling during installation and removal cycles, extending fastener service life across multiple builds.

This kit suits street engines, marine applications, and high-output racing builds where conventional factory mains prove inadequate. The 2-bolt configuration maintains OEM deck geometry while the studded design allows precise torque specifications for consistent clamping force. Installation requires proper torque sequencing and complementary main cap hardware; compatibility with Big Block Chevy blocks (BBC) is universal across generations, making this essential for frame-off restorations, engine rebuilds, and performance upgrades.
