Advance Adapters gears?
« on: Feb 06, 2021, 05:09:05 AM »
Does anyone have any experience with the Advance Adapters 4.7:1 gear set? The splines on the input gear in my T-case are pretty worn and I am thinking of replacing the input gear. This pretty much means buying a whole new gear set. Unfortunately, Marlin's gear sets are never in stock and I'm beginning to think they never will be. I also hate the idea of buying Trail-gear.

Poking around looking at Atlas T-cases I saw that Advance Adapters offers a 4.7:1 low range set that is made by Sumo Gear (Toyota's OEM supplier, according to them). Anyone run them? Know anything about them? I really can't afford an Atlas and Marlin Crawler gears seem to be made of unobtanium.

Thanks!

Never mind. I just got an email saying they're back in stock.

The first set must have over 300k miles on it by now and has held up super well for me, but with my truck doing tractor duty during firewood hauling season I think it might be time for some new, not-worn Marlin Crawler goodness  :thumbs:
