Time to re-gear/help

Really, it depends on what type of performance you want and what you use your truck for.

When I regeared, I wanted a slightly lower final ratio with bigger tires than what the factory setup was. My truck was somewhat underpowered from the getgo. I drive my truck every day, and do one or two cross country trips of 4000+ miles every year. I still needed daily drivability. I went with the gears that would run my new tires slightly lower than the factory setup did. If it was mostly a trail rig, I would have gone lower.

This is the calculator I used: http://www.grimmjeeper.com/gears.html

really only you can determine what gears fit you best.

 

Do the 4:88's you will never regret doing it right the first time !!!

 

To get stock with Mt you need 4.30

4.56 is over geared. ~2800 rpm at 70

 

Seriously, who wastes the time or money building and installing 4.30s in a taco. If you're on 33s leave the diff alone and suck it up. The 4.0, though gutless, can deal with it. With 35s the 4.0 sucks on stock gears but i think we all agree with that.

 

I agree with everything you said. I wouldn't regear for 33s. 4.30s are not a good option. 4.56 sucks on the highway unfortunately. There are no real good options. I wonder what 4.10 would do

 

Shit I'm thinking 4 cyl MTs. All the 4 cyl have 4.10's. My bad.

I'm on 4.56's on 33's. I run 2,700 at 70 IIRC. So putting 4.56's on 35's would run a lower RPM than that. Closer to factory.

 

I'm on 35s and 4.56

My numbers are real world.

 

No, only the 6luggers but unless TRD off-road those 4.10 diffs can be swapped into V6 trucks

 

Most of the trails i go require a lot of highway driving to get to, so 4.56 will put me on the higher rpm running 33s on the freeway, whats the desired RPM on highways driving @ 75mph, 2000-2500rpm? so 4.56 with 33s is good for city driving but no for highway driving, if i change to 35s with the 4.56 will my truck performe better on the highway? is there gear ratio that puts me in between, i mean 50/50 city/highway? thank you guys for all your input
Ill be making a couple phone calls to get an idea of whats best for my set up.

 

On a V6 the 4.56 gears on 35s is about the closest to factory RPM ranges.

4.10 on 33s.

 

ugh no.

6 lug trucks.... regardless of 4x4 or prerunner or TRD package. i4's got 4.10's, v6's got 3.73 from the factory. No exceptions.

OP go for 4.30's

 

For reference... 33s on 4.56 gears. V6 Auto

75mph at 2600 rpm.

 

Shove it Sally! Can you even read?
Good luck bolting a 4.10 diff from a 4banger into a TRD off-road elocker axle haha. Nothing I wrote is wrong.

 

Are you auto or manual?

 

^^

 

Well then he needs to stop confusing the OP. OP will not get those same numbers. 4.56 on 33s and manual trans he is going to be screaming on rpms

 

It's not just about RPM- also engine load.

 

Engine doesn't give a shit. You're not gonna wreck it with either gear setup.
@gainman is making valid points about screaming on the freeway. 12-13mpg hwy is absolutely fucking terrible. This thread is now a dead horse. Ther s tons of good advice, some usual misinformation that has been corrected and OP now needs to decide what's more important. Hwy mpg or off the line giddup
