Carrillo BMW/Toyota B58 - CC 5.828in Pro-H 3/8 WMC Bolt Connecting Rods - Set of 6

These are Carrillo Pro-H connecting rods, a well-built set specifically for BMW and Toyota B58 engines. If you're building a high-performance B58 engine, whether for track use or serious street performance, you need connecting rods that can handle the increased stress. These rods are designed to be a strong upgrade over stock, offering improved durability and reliability under demanding conditions. They feature a 5.828-inch length and come equipped with 3/8-inch WMC bolts, a common and robust choice for performance applications.

Carrillo is known for making strong internal engine components, and these Pro-H rods are a prime example. The Pro-H beam design is a popular choice for its balance of strength and weight. They are forged from high-strength steel, then heat-treated to ensure they can withstand the significant forces generated by a performance B58 engine. The WMC bolts are also a critical part of the assembly, providing a secure and reliable connection. This set includes six rods, enough for a complete six-cylinder B58 engine build. When installing, always refer to the manufacturer's specific torque and assembly procedures to ensure proper function and longevity.

This set of connecting rods is a significant investment in the foundation of your B58 engine. They are intended for builders who are pushing the limits of the stock engine and require components that can reliably handle higher horsepower and torque. Ensure you have all necessary supporting components for your build, including pistons, rings, and a full engine gasket set, before beginning assembly.
