Just go buy a different T-case, 3.15's are OK but they kind of fall in between 2 more useful ranges those being 2:1 and 4:1. You end up loosing a good cruising low range and they still stall out during more technical crawling, i think stock or 4:1 would be better depending on how you wheel. If your wheeling style is more diverse look into an Atlas 4 speed or Stak 3 speed, if you're on a budget go with a doubler/D300.
