i want to have a what people keep calling a 4 to 1 ratio on my truck, i have a 86 ranger, man tranny and the v6, the t case looks pretty ez to get to, is that all i would have to do to have that ratio difference on it?

and i was hopeing to cut out the fenders on it, anyone ever done fender cutting b4? any help would be nice

what does that have to do with Radio's? do you mean crawl ratio? if so your going to have to do alot more than cut the fenders.

I dont think they make a 4-1 transfercase geardown for rangers you would have to get a different case

[Rockinelle]

What cases did those come with?

your crawl ratio depends on how many times your transmission output shaft turns (commonly measured in 1st gear) in relation to how many times your crankshaft turns, multiply this 1st gear ratio by your transfer cases' ratio, how many times your transfer case (in lowrange) turns the driveshaft in relation to your transmissions output shaft, multiply this result with your ring to pinion gear ratio (I have 4.11 "gears) in your differential, the result (1st gear x transfer low range x differential gears = crawl ratio.

Here's where it gets complicated, the torque produced by your motor will turn smaller diameter tires easier than larger diameter tires, work = force x distance, larger diameter tires travel a farther distance with a single rotation of your axle than smaller tires however "less force" eventually results in bogging your motor to a stop, thus counter intuitively resulting in a need for more torque.

And now I've risen to my level of incompetence. But you should be able to pick a spot above to increase your crawl ratio.

The best thing to do is look at other rangers that have their fenders cut, and pick which one you like the best. Then draw a line using chalk to how much you want to cut out, and the look you want. Then you get your grinder and start going.

your crawl ratio depends on how many times your transmission output shaft turns (commonly measured in 1st gear, mine is 7 to 1) in relation to how many times your crankshaft turns, multiply this 1st gear ratio by your transfer cases' ratio, how many times your transfer case (in lowrange, mine is 2.32 to 1) turns the driveshaft in relation to your transmissions output shaft, multiply this result with your ring to pinion gear ratio (I have 4.11 "r&p" gears) in your differential, the result (1st gear x transfer low range x differential gears = crawl ratio) is your crawl ratio, (mine is 7x2.32x4.11=about 66 to 1.

p.s. i.e. a taller set of gears in your diff's or transfer case or transmission

[toyoder]

yea all what he said twice

I'd like a set of taller gears maybe 6 to 7 feet taller.

yeah i know how ratios work, i was just wondering how hard it is to put a 4.11 or what ever gear that fords make into a stock t case, sounds like i have to just get a new t case but do i really have to do that.
anyone know of some places that i could look at other rangers to see how far i should cut my fenders?

thanks

4.11 that are your diff gears and that is a good set. there is a kit out there for the fenders they are fiberglass and leave lots of room for travel.

O i c , guess everytime ive heard 4.11 or 4.56 i thought t case. so then i guess i would have to get a whole new set of gears in my diff to change that.i no alittle about diffs but not alot. :read:

anyone know how much a fiberglass fender cut out would be for that year of ford?
