Proper support via upgraded main bearings is crucial to prevent oscillations and wear that can damage the crankshaft and other components. 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.
Know What You Are Buying:
Subaru main bearings are specific to a #5 journal bearing position. Journal bearing position is not VIN or year specific, it must be known prior to purchase. Please be sure which bearings you need as engine internals components are not eligable for exchange or return.
