So far she has been running fine, but my cousin is starting to say that running my 33 inch mickey t mtzs are gonna ruin my tranny and rear end. is he right or is he jealious that i bleed ford blue and he has a chevy?

 

What tranny/rear end do you have? Gear ratios?

 

i never checked, whatever a stock fx4 has

 

auto trans

 

dont stock fx4s come with 4:10s?

 

There should be a code on your door sticker near the stock tire size...see here to decipher the code: http://www.therangerstation.com/tech_library/Axles.html

 

Ruin it.. No.

Add some extra weight and strain/wear... yeah a bit.

 

if you have an FX4 with the 8.8 rear end with 4.10's then you are perfectly fine. It is plenty strong! as well as the tranny. Both are just fine! Jealous = maybe

 

yea thats what i figuered, imma try deciphering that code tomm, but im positive i should be fine. I think hes just jealious that hes running a little s10 with no character and i got me a fx4 beast! fx4 4 life baby!

 

thanx for the info and posts guys

 

wrong.

on that quote.. mine doesn't have a 31 spline axles, FX4 rangers didn't start till after atleast 01.. 4.56 is very rare, if it was even done.


where ever you got that....

 

it's gonna add stress to the components...

Stress = Wear&Tear...

 

The FX4 wasn't introduced until 2002. In that year it was essentially a FX4 Level II that's 2003+. It had a 31-spline axle with 4.10 or 4.56 ratio. The 4.56 was incredibly rare but was offered for a few years.

Being that you have an 06 FX4, you most definitely have 4.10 gears. They weren't offered with anything higher than that. That's easily checked by looking at a small tag on the rear axle pumpkin.

As far as if it'll ruin your transmission or rear end, it won't. Many many Ranger owners have run this setup without any problems whatsoever.

Sounds to me like your cousin has the jealousy bug.

 

I think your wrong, the FX4 did not come with 4.56 gears.

 

Go to www.lapointauto.com Click search and then put that you have a 2003 Ranger and you're looking for a Rear Axle Assm (RWD). The very bottom option is 8.8" ring gear, 10" brakes, 4.56 ratio.

All are reputable local salvage yards but that's a national parts lookup system that is employed by many salvage yards.

The Ranger Station has the same information. Axle code R8 or 98.

Its not saying that ALL FX4's came with 4.56's. I believe only SOME of ONLY the FX4 Lvl 2's came with 4.56's.

 

its rare but they did make them.


as for the original poster, i am running 37s, have 109k miles on the truck and it runs great.

 

Lol but Beard, you don't have a factory transmission OR rear end!!! :)

 

His tranny is upgraded, but it are still factory. The rear end used to be factory when he was running 35s if I remember right.

 

 

it was factory for a long time. i didnt replace or beef up stuff because it failed, i did it because i wanted better/bigger/beefier

 

I'm also an exception.

 

Dont worry about it man..it fine

 

i'm not so sure about the trannys, you can run the 33's just fine. I got some on my ranger with 4.10's. i just hate autos they work but i would much rather run with a manual. it will handle the new meats just fine

 

I've got an 02 FX4 on 33's with 4.10's and an auto tranny with *gasp*166,5XX miles on it. I'll tell you this, flatground, it'll run like a champ, go to climb any hill, and you're gunna loose speed due to being under geared. Now, the flip side to that is I have a buddy who has a 95 STX with 4.56's and he claims he's running almost too steep a gear, so there really isn't a good middle ground on gearing with 33's.
