King Racing – New design for Nissan Applications

As race engines evolve, and become more and more powerful, the need for engine bearings that can withstand the increasingly higher load capacity on these higher power engines is needed. Focusing on Sport compact applications, King Racing has developed the following features that ensure their XP series rod and main bearings can perform under the highest stress and maintain the level of durability and performance they are known for. As part of the sport compact range expansion, King is offering new items for Nissan including the Nissan GTR VR38DETT (Scroll down for the full list of Nissan available items).

pMAX Black™ – This unique tri-metal bearing structure was developed to meet the ongoing demand for increased engine bearing load capacity. The intermediate layer uses a copper based alloy with 4.5% tin for added strength that is the strongest in the industry, at 115 HV. This gives the bearing a load capacity of 17,000 psi in the intermediate! The overlay is also 24% stronger because of a 5% copper alloy with a fatigue resistance of 10,200 psi, 17% more than a standard bearing. King’s SecureBond™ etching process also improves the multi-layer adhesion and structural integrity of the bearing.

U-Groove™ – By using a 90° groove as opposed to a chamfered groove, the effective surface area of the bearing is increased. That in turn, increases the bearing load capacity and gives a better load distribution across the surface of the bearing.

Bull’s Eye Tolerance™ – King’s standard for bearing thickness consistency has set new standards in the industry.  With King bearings, there is no need to purchase multiple sets of bearings to get the right clearance, no need to grind cranks, and no need to adjust housing diameter.

ElliptiX™ – This newly designed oil slot improves oil ingress without affecting the bearing’s surface or compromising the load capacity.

RadiaLock™ – To prevent spun bearings, King has developed a unique process to customize each bearing’s crush height to meet its specific performance demands.

EccentriX™ – By using elasto-hydrodynamic analysis, an optimized eccentricity value for each bearing is reached and the bearing is custom designed using this value to meet specific performance requirements. This process allows a more stable hydrodynamic lubrication regime is reached.

With XP series bearings now available for popular sport compact engines, there’s no reason to look elsewhere when building a performance engine.
