Can't tell you about Mahle, but Sealed Power/FP Diesel (Federal Mogul) has 0.010 destroked pistons for the 6.9/7.3L. I considered them in my recent overhaul but didn't need them. If you can't find them in the Sealed Power catalog, look under FP Power. Same parts but different packaging and more marketed towards the commercial side. I'm running Sealed Power hypereutectic pistons with coated skits in my 6.9L now.
