Description

Today's race engines make more power than ever before. Yesterday's engine bearing load capacity no longer works today' and tomorrow's race engines will be even more powerful. There's a need to meet these demands with higher bearing design standards and improved materials.

HP Series are made of Bi-Metal Aluminum Silicon Alloy. They are best suited 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.
