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

If you're building a high-performance Subaru EJ engine, these Carrillo Pro-H connecting rods are a solid choice for your 1999-2013 Impreza, 2005 Saab 9-2X, or 1991-1994 Legacy. Carrillo has a long-standing reputation for making some of the strongest connecting rods available, and this Pro-H series is designed to handle the increased stress of modified engines. They use their proprietary 3/8" CARR bolts, which are known for their exceptional strength and reliability under extreme loads.

These rods are forged from high-grade alloy steel, then heat-treated for maximum durability. The Pro-H beam design offers a strong yet lightweight profile, crucial for reducing reciprocating mass and allowing your engine to rev more freely. Each rod is precision-machined to tight tolerances, ensuring a perfect fit and balanced rotating assembly. This level of detail is what you expect when building an engine that needs to perform consistently under demanding conditions.

When you're pushing an EJ engine beyond its stock limits, especially with forced induction or other modifications, the connecting rods are a critical component. These Carrillo rods are built to be a direct replacement for your stock rods, but with a significant upgrade in strength and reliability. They are designed to work with standard EJ18, EJ20, and EJ257 engine configurations, making them a versatile option for many Subaru performance builds.
