Product Details


One often overlooked part when building an engine is the bearings. Getting a quality set of bearings can directly determine the longevity of your engine.    ENGINE SPECIFICATIONS: K20A2 K20Z1 K20Z3 K24A2 HIGHER LOAD CAPACITYThe only bearing with load capacity of 17,000psi in the intermediate and 10,200psi in the overlay BETTER FATIGUE RESISTANCEThe only bearing that goes through a hardening process creating a black fatigue resistance shield, which makes the overlay 24% stronger than any other bearing (11.5hv vs 14.5hv) MORE ACCURACYThe only bearings with wall thickness variation of ±.0001” as a standard in comparison to ±0.00025”.  MORE CONSISTENCYfrom bearing to bearing, requiring less adjustment during assembly ONE SET FITMENTThe only bearings that don’t require you to buy multiple sets to achieve desired oil clearance. King’s Unique Technologies 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.
