Overview:
The ACL Rod Bearing Set is a high-performance upgrade designed specifically for the FA20 engine found in the Toyota 86 (2017–2020), Subaru BRZ (2022–2024), and Toyota GR86 (2022–2024). Featuring a .25mm oversized design, these rod bearings provide enhanced durability and reliability for engines subjected to increased power and demanding driving conditions. Ideal for enthusiasts and tuners looking to improve engine longevity and performance, this bearing set ensures optimal clearance and superior load capacity.
Manufactured by ACL, a trusted name in engine components, this rod bearing set is engineered to meet the rigorous demands of high-performance applications while maintaining OEM-level fitment and quality. Whether you are upgrading your engine for track use, forced induction, or extended high-RPM operation, these bearings offer the strength and precision needed to protect your connecting rods and crankshaft.
Key Features:
Designed with advanced materials and precision engineering, the ACL Rod Bearing Set offers the following key features:
- .25mm oversized dimensions for improved clearance and fitment in modified FA20 engines
- High-performance tri-metal construction for exceptional wear resistance and fatigue strength
- Optimized oil clearance to enhance lubrication and reduce friction under extreme conditions
- Precision machined to exacting tolerances for consistent performance and reliability
- Compatible with stock and aftermarket components for versatile application
- Enhanced load capacity to support increased horsepower and torque levels
- Corrosion-resistant coating to extend bearing life and maintain surface integrity
- Manufactured to meet or exceed OEM specifications for dependable operation
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 anti-friction material. This construction provides a balance of strength, flexibility, and wear resistance essential for high-performance engines. The .25mm oversized size accommodates engine builds with modified crankshafts or rods, ensuring proper bearing clearance and preventing premature wear.
Each bearing shell undergoes rigorous quality control and precision machining to guarantee uniform thickness and surface finish. The advanced coating applied to the bearing surface reduces friction and protects against corrosion, contributing to longer service intervals and improved engine reliability.
Installation & Fitment:
The ACL Rod Bearing Set is designed for direct fitment on the FA20 engine variants found in the specified Toyota 86, Subaru BRZ, and Toyota GR86 model years. Installation requires standard engine disassembly procedures, including removal of connecting rods and crankshaft inspection. Proper measurement of bearing clearance with plastigage or micrometers is recommended to ensure optimal fitment.
These bearings are ideal for engine rebuilds, performance upgrades, or repairs where oversized bearing shells are necessary due to crankshaft or rod modifications. Professional installation is advised to maintain engine integrity and performance.
