Part Number: acl5M8309H-STD

Fitment: 15+ Subaru STI

Details:

ACL Bearings are a top choice for engine builders especially for high-horsepower builds.

Here are the details:

• Main bearings

• Standard sized 

• Made using softer metals 

• Designed to allow a thin layer of oil lubricates the connection between the bearings and the crank allowing the crank to "float" to reduce wear

Note: Subaru main bearings are specific to either a #5 or #3 journal bearing position. Journal bearing position is not VIN or year specific, it must be known prior to purchase.
