Carrillo Subaru EJ18/EJ20/EJ257 (WRX Sti) Pro-H 3/8 WMC Bolt Connecting Rods

Carrillo is well-known for making some of the strongest connecting rods out there, and these Pro-H rods are a prime example of that commitment. If you're building a high-performance Subaru EJ engine, whether it's an EJ18, EJ20, or the EJ257 found in the WRX STI, these rods are designed to handle the extra stress. They're a popular choice for builds that push the limits of these already capable engines.

What sets these rods apart is their robust construction. They feature Carrillo's Pro-H beam design, which offers a great balance of strength and weight. This design is crucial for maintaining engine integrity under high RPMs and increased cylinder pressures. The rods come equipped with 3/8" WMC (Wichita Machine Company) bolts, which are a strong and reliable choice for connecting rod applications. These bolts are specifically chosen for their ability to withstand the significant clamping forces and dynamic loads experienced in performance engines.

When you're investing in an engine build, especially for a Subaru EJ, using well-built internal components like these Carrillo rods is essential. They are designed to fit right into the specified Subaru engines, including the 1999-2013 Impreza, the 2005 Saab 9-2X, and the 1991-1994 Legacy. While these are a significant upgrade, remember that a complete engine build involves many parts. Ensure you have all the necessary supporting components, such as pistons, rings, bearings, and a proper crankshaft, to complete your engine assembly.
