Precision-Engineered FB20/FB25 Main Bearings for Toyota Engines
High-Performance Crankshaft Support
Durable multilayer steel backing with advanced aluminum-tin alloy lining ensures optimal load distribution and wear resistance under extreme engine conditions.
Ultra-Precise OEM Specifications
Direct replacement for Toyota part# 12108-AB100 with micron-level tolerance for perfect crankshaft alignment in FB20/FB25 engines (2011-2022 models).
Friction-Reducing Surface Finish
Polished mirror-smooth running surface with micro-grooves maintains consistent oil film for reduced heat buildup in high-RPM applications.
Engineered for Harsh Conditions
Special high-temperature resin coating prevents corrosion from synthetic oils and ethanol-blended fuels in both daily drivers and performance builds.
Batch-Tested Reliability
100% pressure-tested under simulated 200,000km service life to meet JIS D3601 standards - ideal for mechanics stocking shop inventory or fleet maintenance.
