Suby is right on point, as the composite diff gears are very durable. Even better the 16 XB4 Kit comes standard with the upgraded graphite 4 + 2 diff gears.
Super smooth, super quiet and very very durable.
I ran the upgraded graphite 4 + 2 diff gears f/r/c in my 15 and they worked flawlessly. Ninja silent, super smooth. Nice to know there standard for the 16 as they normally run $29 per diff.
