King Performance Main Bearing Set - Size Standard X

Specifications:
Manufacturer: King Bearings
Reference Number: MB5283HPSTDX
Notes: 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 featuring the Alecular metal structure used for high loads for short durations. Suitable for race applications such as drag racing which can benefit from a harder than Babbitt top layer material. Alecular also serves other performance applications that use nodular cast iron crankshafts, such as street/strip and some levels of circle track racing.

King XP & XPC race bearings have already led to new records on the race track. King’s ability to meet the continuously changing and challenging demands of the racing industry with our unique materials and geometric features are a testament to the quality and reliability of our bearings, and reinforces our commitment to developing the ultimate race bearings.

The King Racing line contains engine bearingsfor various segments. Equipped with advanced materials and construction techniques, King Racing bearings extend the limits of power, performance and durability.

To achieve the right clearance, they compensate for bearing thickness inconsistencies by grinding cranks “fat” or “thin”, adjusting the housing bore, or purchasing multiple sets to “fish” for shells. The process is time consuming, costly and tedious. King listened to its engine building customers and responded with Bull’s Eye Tolerance™

Bull’s Eye Tolerance™ is a production technology developed by King. It combines highly accurate machining, overplating, and computerized wall thickness monitoring that adjusts the process on-the-spot.
Bull’s Eye Tolerance™ outperforms the industry’s wall thickness tolerance, ensuring the least thickness variation shell-to-shell. The outcome: A new standard in bearing thickness consistency.

With Bull’s Eye Tolerance™:
• No more multiple set purchases or “fishing” for bearings to reach right clearance
• No need to grind cranks “fat” or “thin”
• No need to adjust housing diameter
• Less taper across the bearing face
