King Engine Bearings CR806HPNDSTDX High Performance Connecting Rod Bearing Set Chrysler 361 383

The King Engine Bearings CR806HPNDSTDX is a high-performance connecting rod bearing set engineered specifically for Chrysler 361 cubic inch and 383 cubic inch B-block engines. This complete set includes 8 pairs of bearings in standard size (STDX) to accommodate stock crankshaft journals.

HP Series with Alecular Technology:

This bearing set features King's advanced HP Series construction with Alecular bi-metal technology. The Alecular structure consists of an aluminum/tin/silicon alloy top layer bonded onto a high strength steel back, providing exceptional performance characteristics for demanding applications. The Alecular structure resists surface migration and extrusion under very high loads, including metal-to-metal contact, over short durations of time.

Performance Advantages:

• Thick .012-.015 inch top layer can be squeezed and worn up to .010 inch without damaging crankshaft journals, with Vickers hardness of 40 that withstands short duration high loads
• Temperature threshold almost 30% greater than tri-metal bearings (450°F vs 350°F)
• Superior macro-particle embedability compared to typical tri-metal Babbitt
• Harder than traditional Babbitt overlay for increased durability under extreme conditions
• Ideal for nodular cast iron crankshafts commonly found in Mopar B-block engines

Applications:

The HP series was developed mainly for drag race and monster truck applications, and is also suited for many performance applications using nodular cast iron crankshafts, such as street, strip and some levels of circle track racing. This bearing set is compatible with Chrysler, Dodge, DeSoto, and Plymouth vehicles equipped with 361ci or 383ci B-block engines.

Each King bearing is manufactured using proprietary Bull's Eye Tolerance technology for precise wall thickness consistency, ensuring optimal performance and reliability. All bearings are produced in King's state-of-the-art facility where rigorous quality control measures guarantee only the highest quality bearings reach the customer.
