Present day everyone is using a gear diff, which are very durable. So much so that majority of buggy brands are now offering a solid axle spur to bypass it.

Now you're not taking jumps many feet in the air like an off-road buggy. So it's not necessary.

The only drive line failure I have read from the rally guys in Colorado is the wearing of the spacer next to counter gear.
