INDUSTRIAL INJECTION PDM-MS-2218HC GM H SERIES MAIN BEARINGS FOR 01-16 6.6L DURAMAX

2001-2016 Duramax H Series Main Bearings (Std .025) 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.

Elevate your engine's performance with the INDUSTRIAL INJECTION PDM-MS-2218HC GM H SERIES MAIN BEARINGS designed specifically for the 2001-2016 6.6L Duramax. These high-quality main bearings, featuring a standard size of .025, are specially coated for optimal durability and performance, making them an excellent choice for both competitive racing and everyday applications.

Crafted with precision, the H series bearings are engineered for high-stakes environments like NASCAR, yet versatile enough for all types of competition engines. Each bearing boasts a medium level of eccentricity and a hardened steel back, complemented by a superior thin overlay that enhances longevity and reliability. Enlarged chamfers ensure greater crankshaft fillet clearance, while the elimination of flash plating enables better seating, resulting in improved performance and efficiency.

For those seeking even more clearance, the HX series bearings provide an additional .001, ensuring a tailored fit for various engine configurations. The primary advantage of the coated bearings is their ability to mitigate damage during cold starts and situations where oil starvation may occur. This innovative design addresses one of the most critical times for engine wear, as cold oil is slower to circulate.

With added dry film lubricant coatings, friction is significantly reduced, leading to prolonged bearing and crank journal life. The special coating comprises moly and other essential ingredients that not only retain oil but also enhance the overall lubrication process. Originally developed for high-performance race engines, this technology has been adapted for street and daily-use vehicles, giving you the durability needed for all driving conditions.

Sold as a complete set, these main bearings are a crucial component for any serious engine builder or automotive enthusiast looking to maximize performance and reliability. Experience the difference in your engine with INDUSTRIAL INJECTION's advanced technology.
