Ive got a '94 F150 4x4 Im running 33 inch tires on and was wondering what gear ratio would be best for it. The truck is a 4.9 with a 5 speed and 3.08 gears, needless to say it has a time pulling 33's. I have a set of 4.10's but dont know if thats too low? I wheel the truck some and pull a trailer so I just want to find a good all around gear. Anyone have any suggestions??

Search, and read the Gears sticky.

Regearing is extremely expensive. IMO, do it once and pick the ratio you're most likely to use for a long time. 4.10's are fine for 33's, but too low for 35's, so if you ever plan on going with bigger tires, you might want to consider it.

Try the search feature, it works wonders. Here is what you will find.

I plan on staying on 33's so 4.10's sound like a good option, plus I dont wheel the vehicle too hard so I dont need an extreme low gear. Thanks for the info too it was useful!

I'd use the gears you have there. I have 3.55's with 31's and I wish I had at least 3 73's.

Hah, I was looking at this thinking when the heck did I post this? I had to think if I was drunk last night...

you cannot get 3.73's for the bronco

 

[slw210]

Why not? They sell them, except it would be a 3.70 for a 9" and 3.73 for the 44 and 8.8.

 

[Rednek]

yep. thats true. 3.73 is sold for d44 front and 8.8 rear. i have like 5 magazines that say so.


for the 8.8

Broncos never came from the factory with 3.73's. So you're still proved wrong on your chit at least.

I know it's not in drive. I accelerated from a dead stop in first to 5000rpm, then slapped it into second and continued up to 85, and took the picture.

Took this one a few days ago, and now the 302 has 209,000 on it.

Dana never made them, and POS yukon just started offereing them it must be.

I still would not run them. I have never cared for yukon gears. I will stick to the better brand names. besides most broncos came with 355's. Who in thier right mind would regear to 3.73's.

:stupid

Even the difference between 3.55 and 4.10 isn't enough to warrant the cost, IMO. This re-gearing shit gets expensive quickly, moreso if someone else is doing the labor. I've said it before, but I'll say it again: I'm on 31s and saving for 4.56 gears. Even at 85 mph, I'll still be under 3000 rpm! Compare that to the ~2300 rpm I'm pulling at that speed now, and it's clear to see the difference isn't as much as you'd think.

Hell, my Mustang has 3.73 gears on tires that measure 25.6 inches in diameter (225/60-R15), and that thing has no problem gettin' its freak on at expressway speeds. With these larger tires, the gearing really needs some help!

 

[OzzyZig87]

I dunno i'm am still 50/50 on regearing on my 90 bko. 33's with 3.55's isnt too bad, i rarley do any long distance highway driving so I can stay under 2,000 rpms while doing like 55.

 

[Rednek]

i said i thought he swapped from 3.55 to 3.73. no it does no tmake sence... but idk.
you told me they never made 3.73 for any bronco. and i proved you wrong
goodfight

Dana never made them, Ford never offered them in the bronco.

yukon just started making them recently. Why I have no friggen idea. Either way. going to 3.73's are retarded.

 

[95f150SKU]

not to but in or anything but, what would be a good gear ratio for a auto-tranny, 4x4 and im looking to upgrade to 33's and im trying to squeeze all the mpg i can.

Forget it.

damn thats wierd cause my bronco with the 3:55s would only get to 70mph in second and shes screamin bouncin off the rev limiters. now with my 4:56s its roughly 62 mph before she starts hating me but she gets there QUICK. Mind yalls this is only on 31s:banghead.

yea, but he's starting with 3.08.

I think the 4.10 would be a good match.

I agree. back a few years ago when I went to 33s I went from 3:55s to 4:10s and though it was an improvement and gained back some gas mileage I lost when I went to the larger heaver 33s I should have gone 4:56s as I only had the OEM type of power - felt very factory with 4:10 and 33" tires.
