Upgrade your Subaru WRX or WRX STI with the ACL Race Main Bearing Set for journal position 3, designed specifically for 2002-2014 WRX and 2004-2021 STI models. These premium bearings use a softer metal to protect your crankshaft and engine block from wear, ensuring long-lasting engine performance and reliability. Proper main bearing support is essential to reduce crankshaft oscillations and prevent costly damage.

ACL bearings feature a thin oil film that lubricates the connection between the crank and bearings, allowing the crankshaft to “float” and minimize friction. This set is tailored for journal position 3, which is critical to confirm before purchase, as it is not determined by VIN or year alone. Ideal for Subaru enthusiasts seeking durable, race-ready engine components, this bearing set helps maintain engine integrity under demanding conditions.

Trust Subimods for specialized Subaru parts that deliver quality and fitment precision. Upgrade your engine’s durability today—confirm your journal position and shop with confidence.
