Product Description
Race-bred durability for your 6.6L Duramax build. INDUSTRIAL INJECTION’s PDM-MS-2218HC is a coated, H-Series main bearing set engineered for high load and high RPM. Based on the proven Clevite/MAHLE H-Series geometry, these bearings add a performance anti-friction coating to help during cold starts and transient oil-film events—ideal for serious street/track and towing builds.

Helpful Notes
- Measure everything. Always confirm housing bore, journal size, and oil clearances; line-hone as needed.
- Replace thrust washers whenever the crankshaft is out; verify crank endplay on assembly.
- For extra oil film in high-load builds, consider the HX (+.001") variant linked above.
FAQ
Are these standard size?Yes. PDM-MS-2218HC is a standard (STD) size coated H-Series main bearing set for OE journal dimensions.
Do these include thrust washers?No. Order TW-610S separately and verify endplay during assembly.
What’s the difference between H and HX?H is the standard race geometry; HX adds about .001" extra oil clearance for higher load/RPM or larger fillet cranks.
Why use coated bearings?The coating adds scuff resistance and protection during cold starts or momentary oil-film collapse—useful in performance and towing applications.
