2017–2020 Toyota 86 / 2022–2024 Subaru BRZ / 2022–2024 Toyota GR86 FA20 Engine
5M8312H-.025
Overview:
The ACL High Performance Main Bearing Set oversized by 0.025mm is engineered specifically for the FA20 engine found in the Toyota 86 (2017–2020), Subaru BRZ (2022–2024), and Toyota GR86 (2022–2024). Designed for enthusiasts and professional builders seeking enhanced durability and reliability, this bearing set provides a precise fit for engines requiring an oversized main bearing solution. It is ideal for performance rebuilds, engine upgrades, or maintenance where improved bearing clearance and strength are critical.
ACL’s reputation for quality and performance ensures that these bearings deliver consistent oil film retention and superior wear resistance, helping to extend engine life under demanding conditions.
Key Features:
This high performance main bearing set incorporates advanced engineering and materials to meet the rigorous demands of modern sport compact engines. Key features include:
Construction & Design:
ACL main bearings are crafted using a tri-metal construction that combines a steel backing with layers of copper-lead and a thin overlay of babbitt material. This combination provides excellent conformability and embedability, allowing the bearing to adapt to minor imperfections in the crankshaft while resisting fatigue and wear. The oversized 0.025mm dimension ensures a precise fit for blocks that have been machined or require additional clearance, maintaining optimal oil film thickness for reliable operation.
Each bearing shell is precision ground and honed to exact tolerances, ensuring consistent journal contact and smooth crankshaft rotation. The design incorporates strategically placed oil grooves and holes to maximize lubrication flow, reducing the risk of metal-to-metal contact under high-stress conditions.
Installation & Fitment:
This bearing set is a direct replacement for the main bearings in the FA20 engine of the specified Toyota 86, Subaru BRZ, and Toyota GR86 model years. Installation requires standard engine rebuild procedures, including proper measurement of crankshaft journals and bearing clearances to confirm the oversized dimension is appropriate. No modifications to the engine block or crankshaft are necessary beyond standard machining practices.
Professional installation is recommended to ensure correct bearing clearance and alignment, which are critical for engine longevity and performance.
What's Included:
Ideal For:
This ACL High Performance Main Bearing Set is ideal for automotive enthusiasts, tuners, and engine builders working on the Toyota 86 (2017–2020), Subaru BRZ (2022–2024), and Toyota GR86 (2022–2024) equipped with the FA20 engine. It is especially suited for those performing engine rebuilds, upgrades, or repairs where enhanced bearing durability and precise fitment are required. Whether for street performance, track use, or motorsport applications, these bearings provide the reliability and quality demanded by high-performance engines.
ACL Race Series is known for performance engine bearings used across motorsports, with rod and main bearing options engineered for durability under high load and heat. Their positioning centers on racing-focused design, metallurgy, and engineering intended to stand up to demanding competition engines.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
