King Bearings developed the HP Series, featuring the Alecular bi-metal composite. The Alecular technology made to better resist extrusion & material migration under high load for short duration or medium load for long duration, particularly in applications such as drag racing, monster truck and tractor pull competitions.
Commonly use for applications requiring a harder than Babbitt top layer to better resist extrusion & material migration (drag racing, monster truck, tractor pull). Also for all other applications using nodular cast iron crankshafts

Tech Features

Aluminum Based
aluminum base
Bi Metal Aluminum material

Lead free Aluminum based material used for low to heavy load engines

Bi Metal high Performance

HP-developed mainly for drag race and monster truck applications using nodular cast iron crankshafts.

Narrowed Bearing Length

Enabeling to clear large filet cranks.

Dowel Hole
Additional Stability for the Shell

Enables adding a locating pin, thus improving bearing stability particularly in aluminum housing, that may be compromised by excessive housing expansion and loosing bearing press fit, that occurs in extreme heat conditions.

Optimal crush height and heat transfer

An optimal crush height value obtained from an optimization process of each performance bearing crush height

Superior hydrodynamic lubrication

An optimized eccentricity value reached through elasto-hydrodynamic analysis and dynamic calculations.

Bulls Eye™
Bull's Eye Tolerance

Outperforms the industry’s wall thickness tolerance, ensuring the least thickness variation shell-to-shell.

Lead free
Lead Free
Environmentally safe composite

A lead-free bearing material prioritizes environmental sustainability and safety, utilizing alternative compounds to achieve optimal performance in diverse applications.
