I want to re-gear up from my stock 4:10's. My dilemma is 4:88 or 5:13.
I'm rolling on 37" ridge grappler tires that actually measure 35.77" @ 28psi.
I do trail ride and moderate wheeling, my concern is interstate driving.
Currently I'm taching 1900 rpm at 75 mph. Which of course is on flat highway without any incline.
Even 5th is a struggle to pass anyone if need be... unless I drop to 4th.
I think I'd like to be around 2300 rpm at interstate speeds in 6th. So maybe I'm leaning 5:13.
Is there any downside to going that tall besides the gas mileage?
Any added heat, wear and tear etc?
Thanks in advance for any know-how or expertise.
