Designed to provide enhanced durability and reliability under demanding conditions, this bearing set is ideal for enthusiasts seeking to maintain or improve engine performance during spirited driving or track use. Featuring extra oil clearance in a standard size, these rod bearings help ensure optimal lubrication and reduce the risk of bearing failure in high-stress environments.
Whether you are performing an engine rebuild, upgrading your vehicle for motorsport applications, or simply replacing worn components, ACL’s rod bearings offer a trusted solution that meets the rigorous demands of modern performance engines.
Key Features:
ACL rod bearings incorporate advanced materials and design features to deliver superior performance and longevity. Key features include:
- Extra oil clearance for improved lubrication and heat dissipation
- Standard size to fit factory specifications without modification
- High-quality tri-metal construction for enhanced wear resistance
- Precision manufacturing to ensure consistent thickness and roundness
- Optimized surface finish to reduce friction and prevent premature wear
- Engineered specifically for the FA20 engine’s unique demands
- Compatible with both street and track driving conditions
- Manufactured to meet or exceed OEM standards
Construction & Design:
ACL rod bearings are crafted using a tri-metal layering process that combines a steel backing with a durable overlay of copper-lead alloy and a thin layer of soft metal to provide excellent conformability and embedability. This construction ensures the bearings can withstand high loads and resist fatigue, even under elevated RPMs and increased cylinder pressures common in performance applications.
The extra oil clearance design allows for improved oil flow around the bearing surface, which aids in maintaining a stable oil film and reducing the risk of metal-to-metal contact. This is particularly beneficial in engines subjected to high thermal and mechanical stress, helping to extend engine life and maintain smooth operation.
Installation & Fitment:
The ACL High Performance Rod Bearing Set is designed as a direct replacement for the factory rod bearings in the specified Toyota 86, Subaru BRZ, and Toyota GR86 models equipped with the FA20 engine. Installation requires standard engine disassembly procedures and should be performed by a qualified technician or experienced enthusiast. Proper cleaning, inspection, and measurement of crankshaft journals are recommended to ensure optimal bearing fitment and performance.
No modifications to the engine block or rods are necessary, making this bearing set a straightforward upgrade or replacement option during engine rebuilds or maintenance.
