The new FA20 race bearings are designed with all of King’s racing line features including the pMax Black™ unique tri-metal structure, allowing 24% greater load capacity than any other race bearing available.
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 FA20 to its limits.
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 engines.
The result is a more reliable FA engine that can support higher loads produced in race winning, championship engines.
