A question of size

[Renegade]

I'll be running 32" tires. What gears will the old Renix 4.0/auto be comfortable with? I'd rather go a bit low in case I run 33's in the future.

 

Will a D35 from a YJ bolt in to replace the 35 I have now? Might be able to find one already geared that has been yanked in favor of something stronger.

Thanks! According to that, if I find a D35 from a 4-banger YJ with it's OEM 4.10's, it would work just fine(assuming it bolts in).

I was leaning toward 4.56's, but that could wait.

MY buddy runs 4.10 with 33's and he says they are fine...

4.10's with 33's works just fine. For street use you could easily run 35's with 4.10's.

i run 33x10.5s with 4.10s and it runs perfect. the engine isn't revving to high and the power is good.

so you're saying my 33's with 3.07's isn't a good thing? :P

not unless you want to get beat off of the line by a moped :D

[JeepcoMJ]

uh...time to upgrade...in a few months...when I have money.

3.73 - 4.56 for 33's would be tits :cheers:

 

I think anything above or below would be too much or too little.

 

A buddy of mine has 3.73's and 33's, great for wheeling but not the best off the line ;)

I've got 4.56's and 35's...it ain't that bad... :chillin:

I figured 4.10's would work, just don't want to be lugging the motor & heating up the trans. This truck will only see pavement.

I'm debating on 3.73 or 4.10 righ tnow as my 89 will be the commute truck from here to whitewater (45 min.) for school and will still regularly see highway travel.

 

3.73 sounds best to me...

what size tires?

3.73 has turned out to be a great highway gear comprimise.

my junk get's 22 on the highway loaded for weekend wheeling with the street 31's on it.

 

it's a bit lacking on the trail with 34's, I wish I had 4.56's then, but it's not terribly bad, I don't abuse the clutch that much.

To me gear selection is partly bassed on driving style, and needs for fuel economy. Also it helps to keep your motor in the peak power range for your tires. I always say go bigger/deeper. I say 4.56's or 4.88's that way when inchitis hits you wil be set for gears

I went for a cruise tonite & noticed it is pretty doggy taking off with the 3.55's & "215's". I'm leaning more toward 4.56's now since I will mostly drive short trips & would like the added acceleration. It's not going to be a daily driver. More like a "whenever I feel like it" driver, so I ain't TOO worried about mileage.

[jared]

when i decide to upgrade i am going with 4.88's and 33's 8)

 

but i have a stock 4 bangler tj with 4.10's already :D

[Renegade]

I also have a 4 banger TJ. Running 4.88's with 36" Swamper SX's. Hasn't seen 5th gear in years :roll:
