INDUSTRIAL INJECTION PDM-MS-2328HXC DODGE HX SERIES RACE MAIN BEARINGS FOR 89-18 CUMMINS

1989-2018 Cummins HX Series Race Main ( Std +.001) Coated. These H and HX Clevite bearings were developed primarily for use in NASCAR type racing but are suitable for all types of competition engines.

H series bearings have a medium level of eccentricity, high crush and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating.

The HX series bearings have and .001 extra clearance. The biggest benefit of coated bearings is preventing damage during cold starts and events where oil starvation is evident.

Starting your car is almost the worst thing you can do as the oil has had time to drain out of the engine back into the pan. The oil is cold and thicker and takes time to get circulated throughout the engine, including to the crank bearings.

The added dry film lubricant coating acts as a barrier between the bearing surface and the crank journal. Other benefits are less friction and longer bearing and crank journal life.

The special coating also has moly and other ingredients that retain oil rather than repel it. This coating process was developed for and is used in race engines, and applied to street and daily-use cars to help yield more durable engines.

Designed for high-performance enthusiasts, the INDUSTRIAL INJECTION PDM-MS-2328HXC DODGE HX SERIES RACE MAIN BEARINGS are the ultimate choice for 1989-2018 Cummins HX Series engines. These bearings have been expertly engineered to excel in NASCAR-style racing while being suitable for a wide range of competition engines.

Constructed with a medium level of eccentricity and high crush, the H series bearings feature a hardened steel back paired with a thin overlay to maximize durability. The enlarged chamfers provide greater crankshaft fillet clearance, ensuring optimal performance under the most demanding conditions. Notably, these bearings also do away with flash plating, allowing for superior seating and reliability.

One standout feature of the HX series bearings is the added .001 clearance, a crucial factor in enhancing an engine's overall performance. The key advantage of the special coating on these bearings lies in its ability to protect against potential damage during cold starts and instances of oil starvation. Recognizing that the initial start-up can present challenges due to the oil draining back to the pan, the dry film lubricant coating boosts protection during these critical moments.

This innovative coating not only offers a barrier between the bearing surface and crank journal but also reduces friction, promoting an extended lifespan for both the bearings and the crank journals. Enriched with molybdenum and other oil-retaining substances, the coating is designed to ensure optimal lubrication even when oil is scarce.
