KING RACING HP ALECULAR BI-METAL MAIN BEARINGS - EB-MB557HP-010

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

Main Bearing Set for GM 262, 267, 302, 307, 327, 350 - MB 557HP. 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 - Lead free Aluminum based material used for low to heavy load engines
• Alecular™ - HP-developed mainly for drag race and monster truck applications using nodular cast iron crankshafts
• Narrowed - Enabling to clear large filet cranks
• Radialock™ - An optimal crush height value obtained from an optimization process of each performance bearing crush height
• Eccentrix™ - An optimized eccentricity value reached through elasto-hydrodynamic analysis and dynamic calculations
• Bullseye™ - Perfect clearance in every set
• Lead Free - Environmentally safe composite
