have you regeared?

My Jeep drives fine in stock configuration so no need to regear.
If you put heavier huge tires on the Jeep your results may vary.

Those speed bumps are no trouble?

4.10’s with 35’s and a manual is inadequate. I haven’t regeared yet, but I will be. Probably going to 5.13’s.

I've seen most of the trails that guys ride on in these forums, except for rock crawling I could have done them in my 91 Civic. A dirt road is a dirt road.
Besides at least on public roads there are other moving obstacles, on a trail everything is stationary. My old job required a piss test if you hit a stationary object.
Try Fifth Ave at 530 pm in a 45 foot long vehicle with cabs, people and pedicabs darting in and out.
Driving over rocks would bore me.

Can you explain? I have always seen/been told/read that this is due to not having the proper gearing. My axles are 392 rubicon axles under my sport S

Primary cause of not seeing 8th is having the wrong gears in the axle. If the gears are too tall (lower numbers) you end up with RPMs too low, even at freeway speeds.

I suppose some setting in the software could cause it too.

I have two Jeeps. I only changed gearing on one of them, and I voted yes.

2025 JLR with 2.0T engine. Stock 4.10 gearing was good with stock 33" tires but became inadequate after changing to 37" tires. The large tires with 4.10 gearing really seamed to increase turbo lag, which I didn't like. I regeared to 4.88 gears, and all is well again.

2022 JLUR 392 XR with 4.56 stock gearing. I did not feel a need to regear when changing from stock 35" tires to 37" tires. Two years later I changed to 40" tires, and I still don't feel a need to regear. The 392 makes so much torque that increasing tire size doesn't seem to really matter.

Have you considered a PedalMonster to offset turbo lag? You'll be pleasantly surprised.

4.10s and 35s on my 2.0T, don’t feel any need to regear. Also have 37s on 392 with factory 4.56, it runs them without a problem. If I go 37s on my 2.0T I will most likely regear it.

Okay , yes… I wasn’t understanding what you were originally saying but yeah that’s why I’ll eventually go to 4.88’s … less stress in the drivetrain

Someone else brought up the setting being wrong. Not sure exactly what he meant. I was just jumping in with what I know.

Yup that's is why using a RPM calculator to check gear sizes is the best. Plug in trans, tc, final gears, and tire diameter, then inspect what the new RPM would be at various speeds in various gears.

I've heard of those...

Have you adjusted the computer's settings so it knows you have 35s? If not then that'd explain why it doesn't go into 8th much.

Yours is definitely the best! I've been using it for years.

You've seen dirt roads and think that's what we're building our rigs for?

I'm thinking you've never seen trails that we build our rigs for, at least not in person.

Truth be told I’m not really interested, but the majority of the pictures I have seen on this forum are just dirt roads. I get that people spend a lot of money and time investing in their Jeeps and push them to the limits of what they can do.
I also enjoyed driving to work in blizzards in my Civic with a foot plus of snow on the ground and never getting stuck.
