ACL 4B8310H-.025 FA20 .025mm Oversized High Performance Rod Bearing Set for Subaru BRZ and Scion FR-S

ACL Subaru/Scion FA20 .025mm Oversized High Performance Rod Bearing Set

The ACL 4B8310H-.025 high performance rod bearing set is designed for Subaru and Scion vehicles equipped with the FA20 engine. These .025 mm oversized bearings are intended for properly machined connecting rod journals and provide a precise replacement solution for performance-focused engine rebuilds and service applications.

ACL high performance bearings are engineered to support dependable operation under demanding engine conditions. The bearing construction is designed to promote consistent oil film control, reliable load distribution, and durable performance when used with the correct crankshaft and connecting rod clearances. Professional inspection and measurement of all related engine components are recommended before installation.

This ACL rod bearing set fits select 2013–2016 Scion FR-S models and 2022–2024 Subaru BRZ models equipped with the FA20 engine. Verify the vehicle year, engine configuration, crankshaft journal size, and required bearing clearance before ordering. The .025 mm oversized specification is not a universal replacement size and must match the machining requirements of the engine assembly.

The set is supplied as a replacement rod bearing solution for one engine application. Follow the engine manufacturer’s service procedures for installation, torque specifications, lubrication, and final clearance verification. Improper bearing selection or installation may result in premature engine wear or damage.
