Unbreakable Foundation for Your Duramax Bottom End

Strengthen the core of your GM Duramax LB7 or LLY engine with the Auto Racing Products Main Stud Kit. This essential upgrade replaces weaker OEM main bolts with robust chromoly studs, providing significantly increased clamping force to prevent main cap walk and crankshaft deflection under extreme loads, crucial for high-horsepower diesel applications.

Engineered for Duramax Diesel Power

• Precision-Machined Threads: Rolled threads offer greater strength and allow for more consistent torque readings, ensuring even clamping across all main caps.
• 12-Point Nuts: The included 12-point nuts provide excellent wrenching engagement for precise torque application, critical for maintaining proper bearing clearances.
• Black Oxide Finish: A durable black oxide coating protects against corrosion and provides a clean, professional appearance within the engine block.
