What is the primary benefit of the Pro-H beam design?

The Pro-H beam design is engineered to provide an excellent balance between strength and weight. This helps the engine rev more freely while ensuring the rods can withstand the stresses of high-performance operation.

What does WMC mean in relation to the bolts?

WMC stands for Weld-Forged, Machined, Controlled. This indicates a rigorous manufacturing process for the bolts, ensuring they are strong, precisely made, and reliable under demanding engine conditions.

Are these rods balanced from the factory?

While these rods are manufactured to tight tolerances, it is standard practice for high-performance engine builds to have all internal rotating components, including connecting rods, professionally balanced by a machine shop before assembly.

They are a direct replacement for the factory rods in your S55 engine, ensuring a proper fit during your rebuild or build. This set includes six rods, enough for a complete six-cylinder engine.

Carrillo is well-known for making strong internal engine components, and these rods are no exception. They feature Carrillo's Pro-H beam design, which offers a great strength-to-weight ratio. The material is a high-strength steel alloy, and they come with WMC (Weld-Forged, Machined, Controlled) bolts, which are also very strong and designed to hold up under high cylinder pressures and RPMs. These rods are designed to be a solid foundation for builds aiming for more power than stock, whether you're upgrading for track use or just want a more robust engine.

When you're putting together an engine like this, using well-made internal components is critical. These rods are a popular choice for enthusiasts looking to push their S55 engine beyond its original limits. Make sure to follow the manufacturer's installation instructions carefully, as proper balancing and assembly are key to a successful high-performance engine build.
