Carrillo Subaru EJ18/EJ20/EJ257 (WRX Sti) Pro-SA 3/8 WMC Bolt Connecting Rod - Set of 4

If you're building a high-performance Subaru EJ engine, specifically the EJ18, EJ20, or the EJ257 found in WRX STI models, you need connecting rods that can handle the stress. This set of four Pro-SA connecting rods from Carrillo is built for those demanding applications. Carrillo has a long-standing reputation for making some of the strongest connecting rods available, and these are no exception. They are designed to be a direct replacement for your stock rods, but with a significant upgrade in strength and reliability.

These Pro-SA rods are forged from a proprietary steel alloy, which gives them exceptional strength and fatigue resistance. This is crucial for engines that see higher boost pressures or are used in racing environments. They come equipped with 3/8 inch WMC (Weld-on Machined Cap) bolts, which are a strong and reliable choice for securing the rod caps. The WMC design means the cap is machined to fit precisely onto the rod, ensuring a solid connection under extreme loads. This attention to detail in manufacturing helps prevent rod cap walk, a common failure point in lesser rods under high RPM and stress.

When you're pushing your Subaru engine hard, the connecting rods are one of the most critical components. Investing in a set of Carrillo Pro-SA rods means you're getting a well-built part that is designed to last and perform. This set includes all four rods needed for a complete engine build, making it a straightforward choice for anyone serious about their Subaru's performance and longevity.
