What is included with these Carrillo connecting rods?

This set includes eight Carrillo Pro-H connecting rods and eight 3/8" WMC connecting rod bolts. These are the essential components for replacing the factory rods in your engine.

Are these rods suitable for a stock engine rebuild or only for high-performance builds?

While these rods are a popular choice for high-performance builds due to their strength, they are also well-suited for a stock engine rebuild. They offer improved durability over the factory components, providing a more robust foundation for the S65B40 engine.

What kind of torque specifications should I use for the WMC bolts?

Always refer to the official Carrillo installation instructions for the precise torque specifications and tightening sequence for the 3/8" WMC bolts. Proper torque is critical for engine reliability and performance.
