• Description:

  The Mopar Crankshaft Main Bearing (68440289AA) Brown [+0.127] Class A Lower is a genuine OEM engine component designed to support the crankshaft and maintain proper clearance within the engine assembly. Engineered to Mopar factory specifications, this bearing ensures precise fitment, accurate tolerances, and reliable long-term performance.

  Designed for use in select Mopar engines, this lower main bearing is a Class A (brown-coded) bearing with a +0.127 mm oversize specification, making it suitable for applications requiring adjusted clearances due to machining or wear. It plays a critical role in supporting the crankshaft while allowing smooth rotation and maintaining proper oil clearance for lubrication.

  Constructed from high-quality, multi-layer bearing materials, this component is built to withstand high engine loads, heat, and continuous rotational stress. Its durable design helps reduce friction, prevent metal-to-metal contact, and extend engine life by ensuring consistent lubrication and alignment.

  This component is designed as a direct replacement, allowing for proper installation in the lower position of the main bearing cap using factory specifications. Professional installation is recommended to ensure correct sizing, clearance, and bearing selection.
