King for Subaru

King for Subaru – Continuously Pushing the Limits

Today’s race engines make more power than ever before. Yesterday’s engine bearings load capacity no longer works today and tomorrow’s race engines will be even more powerful.

There’s a need to meet these demands with higher bearings design standards and improved materials.

King Racing’s XP series of rod and main bearings was developed to meet these challenges through technologically advanced geometrical features and a unique metal structure.

Together, they drive the industry to a new level of durability and performance.

King for Subaru FA20 – Push Your FA Boxer Engine to the Max

The Subaru FA boxer engine is the next generation in the evolution of the wildly successful EJ series of engines. While Subaru made many improvements to this generation, some problem areas reveal themselves when pushing the FA to its limits.

King Engine Bearings has been helping to build stronger and more reliable EJ engines for years now, so it made sense for us to apply this experience to the new FA engine platform.

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
