Axle ratio with 35s

[Kermit]

What gear sets are you guys running with the 35"wheel/tire size?

6 th gear is useless and it doesn't crawl even in low range without mega clutch action IMHO

4:10 at the moment.  Want to go to 5:13 at some point.

with that engine i think a 4.88 would be a good swap. i talked to a guy a while back that did 5.13's and he said the rpm's were pretty high on the highway. but, he did have an auto. your sixth gear may be fine at highway speeds with 5.13's. might want to find a JK website where a few guys have tried different ratios. you'll have to consider new differentials at the same time.

I have 4:56's with 35's.   Wish I had 4:88's.

Tanny is an AX-15    5-speed

For  JK with a 6 speed, 4.10's are okay...4.88's will get you back to where 4.10's and 32's will put you.

Honestly, 4.10's are a wee bit tall for 35's. If you're going to stick with 35's I'd say Heeps is right. I'd go with 4.88's.

I run 4.10s with 36s. I have a 4.6 stroker and a T18a tranny. In 4th I am at 2500 rpm at 100 and have plenty of gearing down in low. You have overdrive, so I would think 4.88 would be sufficient. The lower the ratio, the weaker the pinion as it is smaller with less teeth.

I think he's just referring to the fact that you have a D30 up front and the deepest gears available are 4.88.  If you wanted to go deeper you'd have to swap in a 44, 60, etc.  Your rear diff might also have ratio limitations depending on your model.

dana 30 can go to 5.13 and has been able to for a few years now.

4.88 w/ 35" here w/ NV3550 5 speed.  it's pretty decent on road, trail and highway.  only way i would go to 5.13 is taller tires or stop being daily driver.

4.0 with a 6speed and 5.13's and 35's

crawling is a beautiful thing . no issues with anything . can climb straigh up walls in 2nd and just letting the clutch out no gas needed

on the highway is another story im at 3000rpm at 105 km so it sucks for long distance

you complain about your 6th gear being useless now     i complain about my 12st gear being useless
i start in 2nd gear at every light and have no issues what so ever

so 4.88 are probably your best bet ..  i plan on going to bigger tires so 5.13's are ready for my future upgrade

Didn't know that so I just checked it out, Richmond only makes them to 4.88 but Yukon actually goes all the way to 5.38.

I'm planning on 5.13 or 5.38's with the fullsize diffs, but on a 36-37" tire.  On 35's I think anywhere from 4.56-5.13 would be good depending on your use, DD or wheeler.

i have a tired 4.o in my tj with 4:11 (dana44's) and my new 37's and i like it fine. it would be a bit more user freindly if it was a bit lower though i guess.good enought for me considering price to regear. my 0.02

[Kermit]

Thanks... 4.88s it is......start saving again

i used to say the same thing on 37's. Than i went to 5.13's and i can not believe i ever told anyone that 4.10's and 37's were ok.

considering price to regear

What is the cost like to regear?  The gears themselves don't seem overly expensive, labour costs pretty high on a job like that?
