You should be fine. However, drive it for a few months before you try to re-gear. You may find that you do not need that. I have the 3.6 with 35s (2-door auto) and I do want to regear but I live in the mountains at 6,000 feet. Wheeling is done from 7,000-12,000. Flatlanders usually don't re-gear with 35s and the Pentastar. With the diesel, I suspect you will not feel the need.
