King XP-Series Tri-Metal Main Bearing Set

Highly modified FA engines can suffer from issues similar to the EJ series, such as low oil pressure and oil starvation causing premature bearing failure.

After thorough analysis, King determined that a complete redesign of the main bearings would allow for increased oil delivery while reducing leakage. By incorporating exclusive King features like Elliptix™ oil ingress and 360 degree oil grooves, oil starvation is all but eliminated.

Plus, King’s SmartLug™ main bearing design shuts the leakage path and resolves one of the weakest links in a high output FA engine. The result is a more reliable FA engine that can handle the higher loads produced in race winning, championship engines. King’s XPG bearings are the key to a reliable high performance FA engine.

Much Better Tolerances Over OEM

These are much more consistent main bearing versus the Subaru OEM main bearings. In my fa20 cyclinder 3 experienced a bearing fail and caused rod know and glittery oil. These balanced much better than other OEM bearings I’ve used before.

GREAT 👍

This product is really good. I heard a lot of people
said this mod is the best to rebuild your engine. I’ll definitely will buy more parts on this business.
