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

2001-2016 Duramax Hx Series Main Bearings (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.

The INDUSTRIAL INJECTION PDM-MS-2218HXC GM HX SERIES MAIN BEARINGS are meticulously crafted for the 2001-2016 Duramax engine, delivering exceptional performance and reliability for various automotive applications. Designed to meet the demands of both competitive racing and everyday driving, these standard .001 coated main bearings offer a robust solution for enhancing engine longevity and efficiency.

Developed with NASCAR-type racing principles, the H series bearings feature a medium level of eccentricity and high crush, ensuring a secure fit within your engine. Made with a hardened steel backing and a thin overlay, these bearings are built to withstand the rigors of competition, while their enlarged chamfers provide greater crankshaft fillet clearance, supporting optimal performance under pressure. Notably, these bearings are free from flash plating, allowing for superior seating and stability.

The innovative HX series takes it a step further with an added .001 clearance, specifically engineered to mitigate risks posed by early morning cold starts and oil starvation situations. The key feature of these coated bearings is their dry film lubricant, which serves as a protective barrier between the bearing surface and crank journal. This significantly reduces friction and prolongs the life of both the bearings and crank shaft.

Additionally, the special coating contains molybdenum and other oil-retaining ingredients, enhancing lubricity and ensuring that your engine maintains peak performance even in challenging conditions. Originally developed for race engines, this technology is now available for everyday cars, delivering unmatched durability and efficiency.

Sold as a complete set, the INDUSTRIAL INJECTION GM HX SERIES MAIN BEARINGS are the perfect enhancement for anyone looking to boost their Duramax engine's performance and reliability, providing peace of mind for both competitive and casual driving experiences.
