FAQ
Will these fit my Duramax?
Yes—fits all 6.6L Duramax platforms from 2001–2016 (LB7/LLY/LBZ/LMM/LML).
Do I need a thrust washer set?
Yes—pair this main set with Mahle TW-610S thrust washers for a complete bottom-end service.
Why “.50 mm undersize”?
It matches cranks ground .50 mm during reconditioning to restore proper oil clearance.
Any machining notes?
Follow Mahle/Clevite guidance for crank reconditioning; many builders nitride/harden when using undersizes and always verify clearances.
