ACL Race Series Extra Clearance Rod Bearings for 4AGE/4AGZE

When building a high-performance Toyota 4AGE or 4AGZE engine, managing oil clearance is critical for preventing bearing failure under extreme loads. The ACL Race Series 'HX' (Extra Clearance) rod bearing set provides the additional breathing room needed for high-RPM operation and increased thermal expansion.

Why Choose Extra Clearance?

• Optimized Oil Flow: The additional 0.001" clearance helps maintain consistent oil film thickness in high-heat, high-stress environments.
• Advanced Metallurgy: Built with ACL’s signature tri-metal construction, offering superior fatigue resistance compared to OEM bearings.
• High-RPM Stability: Specifically designed to handle the increased bearing loads found in modified or forced-induction 4AGE engines.
• Precision Fitment: Manufactured to meet the tightest industry tolerances for a perfect drop-in installation.

Compatibility

These bearings are ideal for performance-tuned 1.6L Toyota engines found in:

• 1985-1989 Toyota MR2 (GT & Super Charged)
• 1987-1991 Toyota Corolla (GTS, FX16, Sport GTS)
• 1990-1992 Geo Prizm GSi

If you are running a built engine with increased boost or higher compression, the extra clearance provided by these ACL bearings is an essential insurance policy for your crankshaft. Enhance your engine's reliability with high-performance components from GGCRACING.
