Default 35s or 37's

I have the six speed rubi with 410 gears I am installing a 3.5 long arm but my question is can the jeep run good with 37's without changing gears. I'm planning on getting a superchip for it. I need feedback and advice thanks

What year Jeep? I have a 2012 Rubicon with an auto and 37's. Runs great with the AEV Procal tune. But that's just my experience with a 2012.

I just put 35's on my Wrangler X last summer. I have 3.73 gears with a superchip and it's pretty good so far. But I definitely notice it. I don't have much experience with 37's but i think it would be manageable.

I have 4.10s and it's great. I know the difference in the motor is pretty drastic, but I have seen guys posting that they are running 37's with 4.10s and the 3.8 V6. I'm sure some will chime in. I would say go 37's and then if you need to regear later do it, just my 2 cents.

That's kinda wht I'm thinking but I don't want to put them on and tear up the engine but I would the to spend the money on 35's and really want 37's

Kinda what I'm thinking but don't want to put 37's and tear up the engine I know I'll need to regear but don't have the money for that yet plus I don't want to spend money on 35's if that's not what I want

I have an 08 and ran 35's with 4:10's on a six speed, it was sluggish but tolerable. I had to regear before switching to 37's

Get the 37s now. You'll wish you had gotten them. You will need to re gear soon but I would just get the 37 s now. I wish I had.
