ACL Race Main Bearings Undersized -.020in - Subaru Models (inc. 2002-2014 WRX / 2004-2021 STI)

Spectral Performance carries a great variety of ACL Bearings to help you with your latest engine rebuild. ACL Bearings are a top choice for engine builders especially for high-horsepower builds.

HIGHLIGHTS:

• Main bearings
• .020" Undersized 
• 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.
