I might just throw an exhaust on it and call it a day. Learn to live with it i guess because I have other priorities for the money.

Before I regeared I just left it in 3rd all the time. If I didn't tow with it I couldn't have justified spending the money for the regearing. But I'm glad I did. Try leaving it in 3rd gear for a week and see how it does. Before I regeared I couldn't let it go into overdrive unless I was doing 70, otherwise itwould just downshift back and forth all the time.

That's how it is currently, shifts like crazy on the highway. I'm afraid leaving it in third will use more gas though and it already guzzles it

Just got another thought. I have some cooper discoverer 31s which are a much more road friendly tire compared to mickey thompson mtzs. Maybe i will run them a couple days this weeks and see if the power or gas mileage is positively affected.

Oh yea, it will make a difference. Those tires have a lot of drag. Another thing, higher rpm's won't hurt you near as bad a lugging down an engine.
Just a thought.

Another thought. Have you reset computer after installing the injectors and coil? That could make a difference too.

Try running 32's and 307's!
Go to 410's then you can get bigger tires later too

Kinda sluggish?...lol
Like I said, I run 32 and 3.07 and its terrible.
Personally I'm waiting to save up and swap a F8.8 in 4.10 so I only have to re-gear the front.........sigh

Dude really just get another set of rims for the 31 and swith em out when your going wheeling. Then regear when yoy can.

XJnLvilleGA

Yup 8.8 im going 3.55s maybe 3.73s. But my next set of tires im going back down to 31s.

I think ill try the other 31s tonight. I'm guessing the computer is reset hecause I have unlocked the battery a few times while working on it since then

i was running 32's on 3.07's on my current jeep and averaging 11-12mpg.

since i regeared to 4.10's the mileage is back up to 17mpg for my last full tank, and plenty of power in 5th gear

dogger15

ive got a 5 speed with 3.07 also. its not bad on the highway just gotta keep it in 4th gear most of the time depending on the wind and how flat the highway is. not sure on my rpm since i have the se edition (no tac) if i was you just got some smaller tires for a dd then when you go roading put the bigger tires back on and put it in 4 lo i had been thinking about re gearing to 4.10s with my 30' tires but its just not worth it to me to spend that much money when it does good now while going up hills and what not would rather get a locker in the rear and call it good

I put the coopers on and will try those on my commute to work tomorrow. I'm hoping for the best.

okay, im looking to run 33 inch BFG ATs, right now im running 31 inch BFG MTs, and i got 3.55, is anyone thinking i will run into much problems?

It seems when you pass that 31 mark everything changes. My number one concern was my trasmission, so I installed a cooler on it. The bigger the tires the more stress on your tranny. When I bought my jeep the fluid was burnt. The AW4's must be pretty tough.
