    4.88\'s too much for 35\'s?

    I don't know what gear ratio to go to. I will be putting a 14 bolt under the rear with 35" Boggers and I'm not sure if 4.56 would be enough to get up and go. Would 4.88's be a wise decision or should I just stick with 4.56? Gas mileage isn't a problem right now for me, because I only drive to and from work and the lady friend drives me everywhere else.

    Since you have an overdrive trans, I think that the 4.88's would work pretty good.

    You should be fine with 35's...

    According to Randy's Ring and Pinion, you will be running 2886 RPM @ 60mph in Drive and 1968RPM @60mph in OD....

    I just regeared yesterday to 4:88 and with my 36" swamps they are fine, in fact I didn't notice as big of a differance as I thought I would going from my 4:10's.

    4.88 with 35s and an O/D trans works great. Go as low as you dare.

    I'm running 4.88's with a 700r4 that doesn't lockup. Right now I'm running 35's until I find a set of 37's. I'm running 2300 rpm at 55 mph. It works great on the highway and I get a whopping 9.7 mpg.

    I have run 4:88s W/35s since last 7 yrs. Dana 60 with overdrive. 350TBI gets about 13 mpg. I have had 3:90 and 4.11s but I really like the 4:88s!
