Clevite H-Series Connecting Rod Bearing

Clevite H-Series connecting rod bearings (also called H-Series rod bearings) are high-performance engine bearings. They were developed primarily for NASCAR-type racing and also suit other competition engines. They work especially well in engines that run in the medium-to-high RPM range. If you're unsure which performance bearing to start with, the H-Series is a common first choice.

Key Features:

• Hardened steel backing with a thin overlay for strength and durability under load
• Medium eccentricity and high crush for secure bearing retention
• Enlarged chamfers for added crankshaft fillet clearance, so they work with crankshafts that have oversize fillets
• No flash plating for better seating
• Tri-metal construction: a copper-lead alloy layer bonded to a steel back, finished with an electroplated babbitt overlay for slipperiness and conformability
• Multiple options across the line, including standard and undersize bearings. Some versions have extra oil clearance for polished journals, and some have narrowed or dowel-hole designs.

For the best fit, aim for a contact pattern that covers about two-thirds to three-quarters of the bearing surface. H-Series bearings are also a good choice if the contact patterns from Clevite P-Series bearings are too narrow.

Clevite is a trusted name in engine bearings. The H-Series gives engine builders a dependable, performance-oriented choice for racing and high-RPM street/strip builds.
