3.73 w/ 33's... What gears to regear to?

Can someone shoot me a link to some reccomended gears to gear to for my Ranger?

I have a 3.0 auto, with 3.73's. It is 2WD. I have 33x12.50's on 15" rims. What gearing do I need??

THANKS!!

4.10's is reccomended. The cheapest and easiest way to do that is to do an "axle swap" from anothe ranger or explorer that already has 4.10's. They can be had for under 200 dollars.


I know of a couple people on this site and RPS that ran/run 4.56's and 33's, they say the power is great, but gas milage isn't.

If it helps any, I'm going with 4.10's and I have the same setup as you right now. I would LOVE to go to 4.56's, but the money is an issue. It will cost basiclly 3x as much to get 4.56's, and 33's aren't goingg to be my largest tire

That sounds like a good combo for our little engines. 33's and 4.56's

I like it to have enough torque to pull a bass boat once and a while, and a tandem jet ski trailer. Right now i'm just worried i'll slip the tranny coming off the dock (it's pretty steep)

I have to keep this thing running awesome as long as I can

I hope this is a joke.


Go with 4.10s for stock performance with best gas mileage.


Go with 4.56s for a lil quicker of the line(but slower top speed) AND a lil less gas mileage. But hey, if u have a buncha extra money to throw around, knock urself out.

Why would it cost 3x as much for 4.56's? The way i've seen gears priced are based on axle not ratio. So wouldnt a 4.10 cost the same as a 4.56? Only thing i can see you meaning is that if you swapped a 4.10 8.8 in you'd get the axle and gears whereas if you did the swap and the gears you'd be paying more for the gears and install which would already be done with the 4.10's.

4.10's w/ 33's on a 3.0... idk. That's what I had and dropped back to 31's for my commute. Idk what it would have been like with 4.56's though. But wouldn't the 4.56's put less stress on the tranny and probably see better city mpg. The tradeoff would be on the highway. I'd like to see what it would have been though. If/when I go back to 33s, I'll probably step up to 4.56 gears. And maybe then go with the B/L and 35s haha

Andy(interceptor) has 35s and 4.10s and they felt fine. His truck was pretty fast(for the 3.0 of course) and I don't know whats with you pushing for the lower gearing. 4.10s is about correct for 33s. I think someone once posted the best ratio is 4.33 or somethin like that, but they dont make that gear size.

And yes you would notice the top speed affect. Your RPMs would be higher going 60 down the highway than if you had 4.10 gearing.

B/c I had 33s and 4.10 w/ a 3.0 and would have liked to have had more low end which would have come with 4.56s. Plus if someone is thinking of eventually going to 35s might as well get the 4.56s anyway. But if the ideal ratio were 4.33 it's right in the middle of the 4.10s and 4.56s... one way leans towards high end one leans toward low end. It's a truck, so I'll take the low end

And that's not how it was worded... I was simply commenting on your truthful claim of a lower top speed... But when I read top speed I am thinking top speed of 96 or whatever it may be... and going to 4.56 may lower it to say 86... it's not often, if at all someone will see these speeds (though 86 more often than 96). But still point being, final top speed is not usually of concern. But yes, the higher rpms doing 60-75 on the highway will be a realistic concern. And that is what I would have like to have known... with a 3.0, 4.56s & 33s, what are the RPMs at 75mph? b/c with the 4.10s I think they were ~2700+ but i dont recall now... with the 31s it's ~2500 i think

Yah but it's too little of a change for too much money to regear one of our trucks. Sorta the "if you're doing it, go big" theory.

The one benefit of goin to 4.56 is once u get bored of 33s u can upgrade to 35s.

Yea, I worded it wrong...

4.10's (if I find a jy axle with em stock) is about 100-120

4.56's (jy axle) 100
(gears) 120
(install) 200


Thats just what I figured out.
