Main Cap Bolt LS Series Inner 6-Bolt w/Tray Stud

The Chevrolet Performance Main Cap Bolt LS Series Inner 6-Bolt with Tray Stud (Part #12560273) is a precision OEM-specification engine fastener designed for LS-series engine assembly. This product is ideal for engine builders and enthusiasts looking to perform factory rebuilds or refreshes on LS engines, ensuring reliable performance and durability.

Manufactured from steel with a black oxide finish, this hex-head main bolt resists corrosion during engine break-in and extended operation. It is specifically designed for 6-bolt main cap configurations and features a tray stud that integrates with the windage tray assembly, which is essential for maintaining proper oil distribution during high-RPM operation.

This fastener is crucial for those performing factory rebuilds or upgrades on LS engines, including the LS1, LS2, LS3, and LS6 variants. Proper installation requires adherence to torque specifications to ensure even clamping load distribution across the main bearing saddle, making it a reliable choice for both stock replacements and performance applications.
