Carrillo Subaru EJ18/EJ20/EJ22/EJ257 (WRX Sti) Pro-H 3/8 CARR Bolt Heavy Duty Connecting Rods

These Carrillo Pro-H connecting rods are built with a strong, I-beam profile, a design that's known for its excellent strength-to-weight ratio, making them a solid choice for high-performance Subaru EJ engines. They utilize 3/8 inch CARR bolts, a detail that speaks to their heavy-duty nature and ability to handle increased cylinder pressures and RPMs. If you're rebuilding or modifying your EJ18, EJ20, EJ22, or the EJ257 found in the WRX STI, these rods are engineered to be a reliable foundation for serious power.

Carrillo is well-known for their robust internal engine components, and these Pro-H rods are no exception. The I-beam design is not just about strength; it also helps to keep the overall weight down, which is crucial for engine responsiveness and reducing stress on other rotating assembly components. The inclusion of 3/8 inch CARR bolts means you're getting a secure and strong connection at the big end, designed to withstand the rigors of performance driving and racing applications. These rods are a significant upgrade over stock, offering peace of mind when you're pushing your engine's limits.

When you're investing in a performance engine build for your Subaru, the connecting rods are a critical component. These Carrillo rods are designed to be a direct replacement for your factory rods, simplifying the installation process. Ensure you have the appropriate machine work done on your crankshaft and block to accommodate these rods, and always follow the manufacturer's recommended torque specifications and assembly procedures for optimal performance and longevity. They are sold as a set, ready to be installed by a qualified mechanic.
