SPEC:

A unique tri-metal structure developed to meet the ongoing demand for increased engine bearing load capacity. 

King Racing’s new hardening technology modifies the overlay’s molecular structure and creates a fatigue resistant shield, capable of carrying 24% more load. 

• 24% stronger overlay 

• 17% more fatigue resistance 

• SecureBond™ - A micro-etch process that improves multi-layer adhesion and structural integrity 

• Compatible with all crankshafts Intermediate layer: 

• Copper based alloy strengthened by 4.5% tin 

• Industry’s highest hardness level - 115HV 

• Load capacity - 17,000 PSI Overlay: 

• Strengthened by 5% copper 

• Industry’s highest hardness level - up to 18.1HV 

• Fatigue resistance - 10,200 PSI

Race geometrical features like U-groove™ - Greater load surface
A unique oil groove design with a 90º groove shape. U-Groove™ increases bearing load capacity by expanding the effective surface area, while keeping oil flow capacity intact. • Better load distribution across the bearing surface • More stable hydrodynamic lubrication regime • Greater bearing durability at high RPM’s

Bull’s Eye ToleranceTM The most accurate clearance in the industry Greater load surface Perfect clearance in every set Wall Thickness Variation
Bull’s Eye Tolerance™ sets new standards in bearing thickness consistency. It outperforms the industry’s wall thickness tolerance, ensuring the least thickness variation. • No more purchasing multiple sets or “fishing” for bearings to reach the right clearance • No need to grind cranks “fat” or “thin” • No need to adjust housing diameter • Less taper across the bearing face

ElliptiXTM - Improved oil ingress
Optimal crush height and heat transfer A superior hydrodynamic regime ElliptiX™ is a newly designed oil slot / oil hole hybrid. It improves oil ingress without affecting the bearing’s surface or compromising the load capacity. • Increases oil passage capacity • Higher oil supply reliability • Eliminates need for custom- made oil hole enlargement

RadiaLock™  - Optimal crush height and heat transfer
RadiaLock™ is an optimal crush height value determined by a robust R&D process that customizes each bearing crush height to its specific performance demands. • Optimal press fit • Improves bearing spin and fretting prevention • Better heat transfer • Reduces bearing and housing distortion 

SmartLug™TM by King - Developed for high performance bearings
SmartLug™ prevents lug generated oil leaks and maintains full bearing surface in the parting line area for better load capacity and oil film distribution. Traditional locating lug designs reduce available load carrying surface area and can cause oil leak paths, especially when located adjacent to an oil groove. SmartLug™ features a locating lug protruding only from the back of the bearing, leaving the bearing work surface intact.

Powersports - Unique tailor made solution for powersports vehicle racing & cruising
Following in-depth research on performance powersports engine needs, King is proud to introduce the industry’s first high performance Powersports engine bearing line. King’s Powersports line utilizes pMaxBlack™, a superior performance bearing structure and overlay, developed by King specifically for professional race teams in various demanding race platforms such as NASCAR, drift, drag, rally and more, and the pMaxKote™, the polymer coated version of pMaxBlack™. Smart design King Powersports connecting rod bearings and main bearings are designed with tight, graded tolerances to preserve the exacting hydrodynamic regime required by high RPMs. They are available in thicker and thinner 5 grades of STD to produce less or more clearance as well as 5 grades of 0.25mm to fit ground/resized crankshafts! These bearings are perfectly suited for both on-track competition and touring/cruising riders. Want to make the most of your ride? Don’t compromise with ordinary bearings… choose King Powersports bearings.
