I have a d44 rear and d30 front with chromos they have held up well for me. I feel as if my setup will hold up to bigger as long as the tires aren't too heavy. I would love like to find a set of 36 iroks on beadlocks.
At Wellsville over the weekend I broke a front ujoint but I'm pretty sure the cap came out even with full circle clips but I will have to look it over again. If that's the case tacking the caps could have prevented that
