2017–2020 Toyota 86 / 2022–2024 Subaru BRZ / 2022–2024 Toyota GR86 FA20 Engine
5M8312HO/S5-STD
Overview:
The ACL Standard Size Main Bearing Set with +0.005 inch outer diameter is engineered specifically for the FA20 engine found in the Toyota 86 (2017–2020), Subaru BRZ (2022–2024), and Toyota GR86 (2022–2024). Designed to meet or exceed OEM specifications, this bearing set provides reliable support for the crankshaft, ensuring smooth engine operation and longevity. Ideal for enthusiasts and professional rebuilders alike, these bearings offer a precise fit and enhanced durability to maintain optimal engine performance under both street and light performance conditions.
Whether you are performing routine engine maintenance or a complete rebuild, ACL’s main bearings deliver consistent quality and peace of mind. The +0.005 inch outer diameter sizing accounts for precise crankshaft journal dimensions, ensuring proper clearance and reducing the risk of premature wear or failure.
Key Features:
ACL main bearings are crafted with advanced materials and manufacturing techniques to provide dependable performance. Key features include:
Construction & Design:
ACL main bearings are constructed from premium bearing alloys selected for their strength, fatigue resistance, and compatibility with engine oils. The bearing shells feature a multi-layer design that includes a durable steel backing, a copper-lead or tri-metal layer for load support, and a soft overlay to prevent scoring and embed contaminants. This combination provides a balance of toughness and conformability, allowing the bearings to adapt to minor imperfections in the crankshaft journals while maintaining structural integrity.
The +0.005 inch outer diameter sizing is carefully engineered to accommodate specific crankshaft journal dimensions found in the FA20 engine, ensuring optimal oil clearance and preventing excessive bearing clearance that can lead to reduced oil pressure or bearing failure. ACL’s precision manufacturing processes guarantee tight tolerances and consistent quality across all bearing shells in the set.
Installation & Fitment:
This main bearing set is designed for direct fitment on the FA20 engine in the specified Toyota 86, Subaru BRZ, and Toyota GR86 model years. Installation requires standard engine rebuild procedures, including proper cleaning of bearing surfaces, checking crankshaft journal dimensions, and verifying oil clearances with plastigage or micrometers. No modifications to the engine block or crankshaft are necessary when using this bearing set with the specified +0.005 inch sizing.
Professional installation is recommended to ensure correct bearing alignment and torque specifications are met, preserving engine reliability and performance.
What's Included:
Ideal For:
This ACL Standard Size Main Bearing Set is ideal for automotive enthusiasts, mechanics, and engine builders performing maintenance, repairs, or rebuilds on the FA20 engine in Toyota 86 (2017–2020), Subaru BRZ (2022–2024), and Toyota GR86 (2022–2024) vehicles.

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!
