Depends on application. I am running a g52 trans 22r 37" tires. It performs close to stock on the road with 5.29s.


For a trail only rig you won't notice much difference, properly setup in a reasonable rig they will both last.

5.71s are VERY sensitive to proper setup, good bearings, proper bearing preload.

That said,

If set up correctly (i'd suggest using v6 3rd members for the larger bearings/heavier casting), they are/can be just as reliable to 5.29s.

EDIT:

I prefer running 4.10 gears for their inherent strenght, I beat the total hell out of my rig, and still break 4.10 from time to time (along with 30 spline longs and tcase outputs)

As others have stated, if set up correctly, 5.71's can last. But take a look at how small that pinion is.............YIKES! No bueno. Stay with the 29's.
