It’s Good To Be The King

The ALPHA line is a polymer-coated series of engine bearings for high-end performance applications. King Engine Bearings was founded in 1960 with one objective: to supply the highest quality bearings available in the marketplace. By specializing in engine bearings, King has built an extensive product offering that includes a wide range of engine bearings. Every King bearing utilizes the highest quality materials and the most advanced designs to ensure complete customer satisfaction. From concept to final product, everything is done under one roof. This allows King to produce bearings more efficiently and with more accuracy in order to keep up with the needs of racers everywhere. During production, all bearings must pass rigorous quality control checkpoints throughout the entire process. This stringent system of multiple quality checks ensures that only the highest quality bearings ever make it into customers’ hands. To achieve the goal of making the world’s highest quality bearings, they reinvented the entire manufacturing process from the ground up, making King a pioneer in developing proprietary manufacturing machinery and multi-function, high speed production lines.

“We have been working with AMS performance for many years now, constantly improving our products. We created narrowed, doweled, and coated versions for GT-R applications, all based on AMS’ technical and on-track knowledge”, says Meytal Snir-Gal, King’s Vice President of Marketing. “This cooperation is a natural continuation of the fruitful work we have been engaged in for years. Unveiling the King ALPHA line in such a challenging time is really empowering as to our stance on the future of our industry.”



Taking Nissan and Infiniti Engine Performance to The Next Level

The combination of the CR6902XPC connecting rod bearings and the MB4524XPC main bearing sets are offered in the ALPHA range for the VQ35HR, VQ37VHR, and VR30DDTT Nissan engines, that are found in the Nissan Skyline (2019) model, the Nissan 350Z & 370Z, and of course the Infiniti Q60 & Q50, among others.

For these applications, King and AMS have created ALPHA versions featuring pMaxKote™ – the top of the line polymer coating that was proven to enhance wear resistance and protect metal-to-metal contact that is possible when creating high load in high-end engines with minimal oil clearance to achieve greater performance. The ALPHA line featuring pMaxKote™ contains ceramic nano particles that function as a fourth layer over the standard pMaxBlack™ coat without changing the bearings original wall thickness dimensions, and while also acting as a solid lubricant for those metal-to-metal conditions. This additional layer also helps protect the engine from oil starvation.

The CR6902XPC and MB4524XPC ALPHA bearings have hit the market at exactly the right time to meet the demand for high-performance bearings that are necessary for superb VR30 engine operation.
