The Main Bearing Set Subaru EJ20/EJ22/EJ25 from DAIDO METAL USA is a precision engine component engineered for rebuilding and high-performance modifications on Subaru's iconic EJ-series boxer engines. Whether you're restoring a classic 2.0L, 2.2L, or 2.5L displacement engine or preparing for forced induction upgrades, this bearing kit provides the critical support your crankshaft demands under extreme loads. OEM and aftermarket builders alike rely on quality main bearings to ensure proper crankshaft alignment, reduce parasitic friction, and maintain reliable oil film thickness during sustained boost or aggressive street use.
This kit features a 0.001-inch undersize specification (V-series profile), which accommodates crankshafts that have been previously polished or repaired to a tighter tolerance than stock. The V-series design is engineered to deliver optimal load distribution, fatigue resistance, and conformability—critical for maintaining hydrodynamic oil wedge pressure in the bearing saddle. DAIDO METAL USA's metallurgical expertise ensures consistent wall thickness, precise bore tolerances, and superior copper-lead overlay performance that withstands the thermal cycling and shock loads inherent in modified and turbocharged applications. The complete kit weighs 0.74 pounds and measures 4 × 2 × 7 inches, fitting standard crankcase configurations across EJ20, EJ22, and EJ25 variants.
Mechanics and engine builders tackling full crank rebuilds, turbo conversions, or engine swaps on Impreza, Legacy, Forester, and Outback platforms will find this bearing set indispensable for maintaining factory-grade reliability and longevity. Installation requires proper crankshaft sizing verification and torque-to-yield fastener procedures; always confirm undersize compatibility with your specific crankshaft before assembly. Pair this with quality oil, precision boring if needed, and correct clamping force to maximize bearing life and protect your investment in a high-output EJ platform build.
