Product Description

The King MB5740XPGSTDX Main Bearing Set is engineered for high-performance and race-prepped Subaru EJ20/22/25 engine builds. Featuring tri-metal construction with a hardened PTFE overlay and pMaxKote nano-coating, these bearings provide exceptional wear resistance, cavitation protection, and seizure defense under extreme conditions. The +0.005" housing bore and XP extra-clearance make them ideal for engines with slight block machining or high oil demand.

Designed for full engine builds across 1992-2025 Subaru models (Legacy, Impreza, Forester, Outback), this set supports turbo and naturally aspirated variants. Sold as a complete five-main bearing set (including thrust), they're sold by pair per journal. Installation note: professional block hone or align honing is recommended when using oversize bearings. These bearings are race-oriented and may require oil clearance matching - ideal for builders pushing the limits in power and RPM.
