4.56 or 4.88

I have a 2013 DC V6 Automatic TRD Off-Road 4x4.

I recently installed a level kit with some 33x12.5. Now I am looking to upgrade my differentials to cutout some wear on my drive train, which is my number one reason for this.

I've read on the forums that I should go with 4.10s but that would require a new clam shell, from what I was quoted. Anyone with some advise about which size I should go with or dealers with mentioning? My end goal would be to have minimal wear on the drive train while still being able to drive on the highway and off-road.

Thank you for your time in helping me make my decision!

 

Personally feel regearing with 33s is unnecessary. I'm on 35s now and will be regearing soon to 4.56.

4.88 would be way over geared for 33s.

 

i would say 4.56 due to strength.

 

4.56 would be ideal for the present and future...in the event you get 35s.
