HN Series Performance Design:

The H-Series rod bearings were developed primarily for use in NASCAR type racing but are suitable for all types of competition engines. These Tri-Metal 77 engine bearings combine the strength of a copper-lead alloy layer with steel backing and an electroplated babbitt metal, providing strength and durability while the babbitt overlay provides critical surface characteristics of slipperiness and conformability.

Key Features:

• Tri-metal construction for exceptional durability and performance
• Enlarged chamfers for greater crankshaft fillet clearance
• Steel backing provides maximum strength
• Babbitt overlay ensures optimal bearing surface properties
• Undersize specification for reground crankshafts
• Suitable for high-performance and racing applications

This bearing is priced and sold individually. Perfect Circle bearings are now manufactured under the Clevite MAHLE brand, maintaining the same quality standards trusted by engine builders and performance enthusiasts for decades.
