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.
