Carrillo Ferrari 308/328/330/348/Boxer/Testa Pro-H 3/8 WMC Bolts - Set of 8

When you're rebuilding the heart of a classic Ferrari, especially models like the 308, 328, 330, 348, or the Boxer and Testa models, using the right internal engine components is critical. These Carrillo Pro-H connecting rod bolts are specifically made for these high-revving V8 engines, ensuring the integrity of your engine's rotating assembly under demanding conditions.

Carrillo is well-known for its robust engine hardware, and these Pro-H bolts are a prime example. They are forged from a proprietary WMC (Wasp Metal Composite) alloy, which offers a remarkable combination of strength and fatigue resistance. This material is crucial for handling the immense forces generated by a performance Ferrari engine. The 3/8 inch diameter is a standard size for many of these applications, and the Pro-H design provides an improved clamping force over stock fasteners, which is essential for preventing rod cap walk and maintaining bearing clearances at high RPMs. Each bolt is precision-machined to exacting tolerances, ensuring a consistent fit and reliable performance.

This set includes eight bolts, which is the correct quantity for a V8 engine. When undertaking an engine rebuild of this caliber, it's always recommended to consult the manufacturer's service manual for specific installation procedures, including proper torque sequences and lubrication. Using high-strength fasteners like these Carrillo bolts is a key step in ensuring your Ferrari engine performs reliably and powerfully for years to come.
