Carrillo Ferrari 308/328/330/348/Boxer/Testa Pro-H 3/8 WMC Bolts - Set of 12

When you're rebuilding a high-performance Ferrari engine, especially models like the 308, 328, 330, 348, or the Boxer and Testa series, using the right hardware is critical. This set includes twelve Carrillo Pro-H connecting rod bolts, specifically designed for these iconic V8 engines. These aren't just any bolts; they are a key component for ensuring the reliability and performance of your engine's rotating assembly under demanding conditions.

Carrillo is well-known for its robust engine components, and these Pro-H bolts are a prime example. They are forged from a proprietary alloy and feature a unique WMC (Weld-Micro-Clean) process, which helps to remove impurities from the material, resulting in a stronger, more consistent bolt. The 3/8 inch diameter and the Pro-H design offer a significant improvement in clamping force and fatigue resistance compared to stock fasteners. This is crucial for handling the high RPMs and stresses these Ferrari engines are capable of producing. Each bolt is precisely manufactured to ensure it fits right into the connecting rod and crankshaft assembly, making them a solid choice for a performance rebuild or restoration.

This set comes with all twelve bolts needed for a complete engine build. Because these are critical engine components, it's always recommended to consult your vehicle's service manual or a qualified mechanic for specific installation procedures and torque specifications. Using the correct torque sequence and values is essential for achieving the intended clamping force and ensuring the longevity of your engine.
