ACL Rod Bearing Set (02+ WRX/STi)

Item # Select Size


When doing rods and pistons, it's a good idea to replace the rod bearings as well. Proper support via main bearings is crucial to prevent oscillations and wear that can damage the crankshaft and other components if the motor should move out of balance. ACL's high quality rod bearings will prevent fatigue, failure, and reduce drivetrain stress through their durable and strong design.

Bearings with extra oil clearance will absorb the stress of higher horsepower motors greater, but will see increased wear during start up. We recommend these be purchased by experienced professionals only.


Size H bearings are a nominal standard size and are used for most applications.

Size HX bearings feature an additional .001" more oil clearance than factory.



  • Subaru rod bearings are specific to either a 48mm or 52mm journal size. Journal size is not VIN or year specific, it must be measured prior to purchase. Please be sure which bearings you need
  • These Bearings are 52mm
  • Sold as Rod Bearing set only (Main set not included)
