Thanks for the quote and info. According to an online rpm calculator my current set up of 4.57 gear and 29" tall tires is giving me 2912 rpm @ 55 mph. Switching to 16" rims and running 235/85/16's will reduce that to 2664 rpm. 60 mph would be 2906 rpm. My 4.57 gear and the taller tires at 70 mph would net me 3391 rpm which would definitely be more at ease than 3706 rpm with the 29" tires! I dont have any plans, for now, to change out the diff for a 4.10, I think just switching wheel/tire sizes will be just fine for the time being. I may go ahead and pick one up though just to have around.
