King Main Bearing Set FA20 / 4U-GSE

You may notice a large price discrepancy across internet on king bearings for the FA20, this is mostly down to there being so different variants of these bearings. Rest assured we only sell the very best version of this bearing which is the pMax Black and pMax Kote coated version. The option we would choose every single time when building a high performance engine. If you have found these bearings cheaper they are likely NOT the pMax Kote version.

pMax Black™ is a unique tri-metal structure for race applications. The overlay is strengthened by a proprietary nano-scaled hardening process that modifies the molecular structure and creates a black fatigue-resistant shield.

pMax Kote™  is a revolutionary new approach to coated bearings. This unique polymer coating is applied over King’s pMaxBlack overlay at the King factory during the bearing manufacturing process. King’s pMaxKote contains ceramic nano-composite particles that function as a fourth layer to enhance wear resistance. pMaxKote does not change the bearing’s original precision wall thickness and adds no additional thickness. It provides additional seizure resistance, superior cavitation resistance, improved wear resistance and protection against oil starvation.

The 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.

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.
