ACL Standard Size High Performance Main Bearing Set (FA20 FR-S)

Extra Oil Clearance High Performance Main Bearing Set. The ACL STD+025 Size High Performance Main Bearing Set is engineered to provide exceptional durability and reliability in high RPM engine applications by incorporating an additional 0.025mm oil clearance for improved lubrication and wear resistance. It is essential for maintaining optimal oil clearance and bearing support, ensuring smooth engine operation and longevity under demanding conditions.

Construction And Appearance. This bearing set features a high strength overlay plate with reduced thickness to enhance fatigue resistance. Constructed from trimetal material (material code F780) with a robust steel back, the liners ensure superior support and heat dissipation. The design includes a 3/4 grooved profile to optimize oil flow and load carrying capacity, finished with precise wall tolerances and enlarged chamfers suitable for performance crankshafts. The bearings come as identical halves to maintain consistent oil clearance and reliable fitment.

Installation. Installation is straightforward and requires no modifications such as drilling. Bearings are designed as direct replacements with identical halves and consistent clearances, facilitating ease of assembly and precise alignment.

Application. This bearing set fits the FA20 engine as used in the FR-S model, tailored to meet the high-performance demands of this application.
