Powerloss is subjective and if you're running 3.21's now, it may seem minimal to you but for someone running a higher gear ratio now, it will feel like a lot.

 

But there would be a loss....

 

A loss from what optimal would be. 4.10's fall in the range of what is acceptable and maybe even good for MPG but a loss of what will deliver good power. Does that make sense?

 

I understand. It's the "optimal range" for the stock 32s. Has good MPG and good power.



I guess all of my problems stem from the fact that I have the 3.21's, and that I'm used to it. If I'm in the same performance range as I have now, then I'd be happy. I think she performs fairly well as is. I'm used to the power, so it's no issue. It has good get up and go when you get on her, and does fairly well on the highway.

I don't see me adding super-heavy components anytime soon. Maybe a stubby for the front, and if needed, a rear bumper with tire carrier (I hope taht wont be needed though... )

I'm sure I'll question this thing 1,000,000 times more before I bite the bullet.

 

To answer your original question: I too live in florida and I have a 2.5" lift, 35's and a 3.73 gear ratio. The tow package on the '08 is 3.73 not 4.10 as someone mentioned. I don't mind how my jeep drives. I don't know the difference and there are no hills in Florida so the power seems sufficient. I have gone off road and into some deep mud and been fine. Being that it's a lease you can easily reconvert it to stock if you keep the wheels, etc. The dealership may even take it back with the mods so that they can sell it for more. Good Luck.

 

How can i tell what gear i have? I have an 07 2 door X and dana 44 without the tow package and sahara wheels and tires. Is there a MPH at a certain RPM in any gear that i can try to match to see what gear i have?

 

the best way would be to go to jeep.com and send an inquiry for a build sheet. Takes about 2 days for them to get back to you but you'll see everthing about your jeep.

 

I called my service dept at the dealership where i purchased my jeep. They told me over the phone. You'll ned your Vin# or atleast the last 8 digits of it.

 

Most dealer's will accept any mods on a leased Jeep, but you will not get what you paid for it. If the mods did any damage (like big lift, stock driveshafts.. busted boot), you will probably have to pay for that, if they notice. Or just be like me, keep it when your lease is over.

 

Wow...thanks for all the feedback. I just wanted to say that if I do mod the Jeep I would buy it at the end of the lease and either keep it or sell it on my own. It sounds like 35's with 3.73's is a bad idea. How much would it cost to regear??
