Oh I no I have had a few just keep a fresh PCV valve in it and your good

it sounds like they may have swapped axels instead of changing the gears plus the jeeps had small axels. but you should be fine. i would say anything over 35s and you should get taller gears tho.

People in Jeeps also have to lift just to get as much ground clearance as I have stock last Guy I talked to had 4 inches on 33's an my trucks axel had him beat by 2 inches...

aight so I'm good but if I go higher then 35' get new gears
and that 300 six can go anywhere I want it to
I already have 31' for mudding but I roasted em and need new ones and I'm looking to upgrade

I'm new to this forum but I got a 96 f150 with a 4 inch rough country lift and a 3 inch body. I got stock 2.73 gears and a 300 inline 6 pullin 37 in Goodyear wrangler m/t military tires. I'm wantin to go with some 4.56 or 4.88, anyone know where a good place to buy them from?

No. Not gonna happen. Fordtrucknut probably abuses his truck off road the most on this forum and I think he has 35's and doesn't want to go any bigger. And he has f250 frame and chassis under that f150 body and engine.

If your offloading, I wouldn't go bigger than a 37" tire for mild, 35" for extreme. Street queen, yeah, 40's will work, but you'll go through brakes like no other and your bearings will hate you. Not to mention your u joints and Knuckles on the front end

What size gears would you recommend for 37s?

most guys run 4.56's for 35 inch tires.... heres a cool chart to look at http://auto.howstuffworks.com/auto-p...size-chart.htm
