Description
ACL's main bearings are made of a softer metal so that you don't wear out your crank or engine block. Additionally, a thin layer of oil lubricates the connection between the bearings and the crank allowing the crank to "float" and reduce wear. Proper support via main bearings is crucial to prevent oscillations and wear that can damage the crankshaft and other components as the motor moves further out of balance.

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.

  • Q: 2004 Wrx  adanvillalobossusd 6 months ago

    Answer

    Will these fit a 2004 WRX EJ20 with OEM Rods and crank and 138k miles? Any machining involved?


    • A: These will fit just fine. These bearings are the OEM spec, but it is recommended that you consult an engine builder to verify machining requirements.

  • Q: Difference between other bearing set?  ironstuner2270974 3 years ago

    Answer

    What is the difference between this bearing set priced at $92.45 and the other bearing set, part number ACL 5M8309A-STD priced at $42? Also for a motor that will be seeing 450-480whp, which do you recommend?


    • A: These are the Race series, which are constructed to better suite higher power/higher RPM operations. For a motor being built to go above the factory power, its suggested to use the race bearings.
