King Engine Bearings Subaru FA/FB (Size .025 Oversized) Main Bearing Set

King Engine Bearings is well-known for making solid engine components, and this main bearing set is a good example of their work. If you're rebuilding the bottom end of your Subaru FA20 or FB20 engine, or a compatible Toyota or Scion engine, these bearings are designed to handle the job. They are a .025 inch oversized set, which is important for ensuring a proper fit and oil clearance when the crankshaft has been machined to match.

These bearings are constructed with a bimetal aluminum silicon base. This material is chosen for its good wear characteristics and ability to work well with crankshaft surfaces. Having the correct oil clearance is critical for engine longevity, and using an oversized bearing set like this helps achieve that when the crankshaft journals are slightly out of spec or have been reconditioned. This set fits a range of vehicles, including the Subaru BRZ, Forester, Impreza, and the Toyota 86.
