• Description:

  The Mopar Crankshaft Upper Bearing (68166596AA) is a genuine OEM engine component designed to support the crankshaft and maintain precise rotational clearances within the engine block. Manufactured to Mopar factory specifications, this upper bearing provides accurate fitment, reliable lubrication support, and long-term durability while helping preserve the engine's original performance and reliability.

  Specifically engineered as a Class 1 crankshaft upper bearing, this component is intended for applications requiring a +0.006 mm bearing size specification. Proper bearing selection is critical during engine assembly and service to ensure correct oil clearance between the crankshaft journal and bearing surface. Maintaining proper bearing clearance helps support stable oil pressure, reduce friction, promote smooth crankshaft rotation, and minimize premature engine wear.

  Constructed from high-quality automotive-grade bearing materials, this upper bearing is designed to withstand high engine loads, elevated operating temperatures, continuous rotational forces, and demanding lubrication conditions. Its precision-manufactured bearing surface helps maintain a protective oil film and supports long-term engine durability.

  Designed as a direct replacement for the original component, this crankshaft upper bearing is manufactured to OEM sizing and grading specifications for proper installation and OEM-quality fitment. Replacing worn or damaged bearings during engine service can help restore proper engine clearances and maintain reliable engine operation.
