King Subaru EJ20/EJ22/EJ25 (Incl. Turbo) Main Bearing Set - Size +0.25mm - MB5382SI0.25
Our TechLab R&D culture focuses on constant analysis of what can be done to support ever increasing race engine loads, and how to improve bearing durability.
One of those technologies is Alecular?.
KING developed the HP Series utilizing the Alecular? bi-metal structure. It consists of an aluminum|tin|silicon alloy top layer bonded onto a high strength steel back. Major benefits of the Alecular? structure are its ability to resist surface migration and extrusion under very high loads, including metal-to-metal contact, over short durations of time. Such conditions may be found in drag racing and monster truck competition.
The HP series was developed mainly for drag race and monster truck applications needing a material that is harder than a Babbitt top layer. These applications require a structure that can withstand high loads for short durations and still offer higher embedabilty and compatibility. In response, KING developed the HP Series featuring the Alecular? bi-metal structure.
The HP series is also suited for many performance applications using nodular cast iron crankshafts, such as street, strip and some levels of circle track racing.
