I can not speak for Trail-Gear's differential gears, but as for Marlin Crawler, we only carry the very best: Yukon Gears.
We have had nearly a PERFECT track record with Yukon gears. The only issue we have had over the years is a customer who ran a High Pinion differential in his rear axle, and as many of us know, the oil pump system in the High Pinion diff does not work when used in the rear axle, and thusly, the gear set burned up.
Yukon gears promise to be the strongest and longest lasting gear sets on the market todayYou can learn more about the high quality Yukon gears at their website linked below:
