Need towing power after bigger tires and lift kit

I just installed a lift kit and bigger tires on my 04 Jeep wrangler sport. I lost way too much pulling power. I need to pull a 5x8 trailer hauling a 4 wheeler at minimum. I was told to change out both front and rear gears but I would be spending more on gas and will lose top end. I can sacrafice this but I would rather not. I do not want a crap load of torque or pulling power just enough to get me up a hill without gearing down my 5 spd. Any ideers would greatly be appreciated. Yes I said ideers. Thanks for yer help.

You need to regear. You gas mileage won't suffer any more than it already is and you won't loose any top end unless you gear waayy to low.

Nothing in this world is free. If you want towing power, you have two choices, smaller tires or lower gears.

You're not the first to make this mistake, there's lots of folks out their trying to set up expedition style rigs who want to tow adventure style trailer only to discover that 35" tires suck for the task at hand.

Gear down or get smaller tires or, don't tow.

I have 33s with factory gears dana 44 rear and dana 30 front I believe is what I was told. So I guess your saying to regear? So how much do I gear down? Also this may sound stupid but how much of a difference would a programmer make if any? I know this has been asked before but how much am I going to pay and do you have any suggestions as to who can do the work if a chain? I know 4wheelparts has the gear package at $450-$856. Thanks guys for your help.

Fill in your profile so we know more about your Jeep. Manual or Auto, what year?

Your stock gears are 3.73 if you have a D44. If you have a manual you will want to get 4.56 gears (or maybe even 4.88 if you do lots of towing). 4.56 gears would net you over 20% more pulling power at all RPMs, basicly the equivilant of 40-50 lbs more torque at the engine depending on RPM, for all RPMs.

Those programmers are not going to do squat for what you want. You might get a couple more HP at very high RPM, which won't be usefull. Regear for usable power.

If you fill out your profile, it'll make it easier for folks to answer your inquiries without further questions.

Now, I'll assume you have the 6 cylinder because you have the D44. For the 6 cylinder, 5-speed manual, and 33's, I'd recommend 4.56 gears.

The install price varies nationally but $1,200 total for both ends is a good ballpark.

Your mileage should not be too bad after re-gear. If you think about it, you're now out of your engine sweet spot and are likely pressing down on the throttle more to make up for the high gearing. When you re-gear, your RPM's will move back into the engine powerband and you won't be pressing down as far on the gas pedal. I'm not saying your mileage will improve but it shouldn't get too much worse either.

Oh yeah, when you get your power back, a smile will come to your face too.

Sounds great guys. Sorry about the profile, its been a while since I have been on here. I will do that and get a pic on here as well. So i guess I am going to regear. I especially like getting that smile on my face part. It may hurt a little when pulling out the wallet but actually $1200 isn't as bad as I thought. I purchased the jeep just for some mud slinging on the weekends with no intent on pulling a trailer but I no longer have my truck so now I have to use the jeep. So it wasnt a mistake fixin up the jeep just bad luck my truck no longer runs. Thanks again guys for your help. Anyone looking to make some xtra cash installing some gears?

Gears are a job best left to a professional that does them every day, for a living. Find a shop that you feel comfortable with and check into thier reputation before they touch your rig. Some folks will suggest you get both the parts and the install at the same shop, just so there is no finger pointing afterward. I was likely lucky, I shopped for my best price online and then shopped around for installation. Just my 0.02...

As others have mentioned, regear and be amazed at how much fun the Jeep is to drive again.

I would add to mrlaine's comment that towing an adventure style trailer with 35" sucks, that towing that kind of weight with no transmission temperature gauge is beyond moronic. Yet, some folks see no problem with it. So, with the towing you are planning on doing, be kind to your transmission and add a transmission temperature gauge.

I spent around $1000 on an AEM cold air intake (with throttle body spacer), RE 62mm throttle body, and a Banks catback exhaust. While I enjoy the very slight performance (and mileage) gains and the change in exhaust sound, even I am going to tell you to regear. You'll spend $200-$300 more than the components I listed, but it'll make way more of a difference. I've got a 4L/5Spd and am going to 33s in March and have already planned on going from 3.73 to 4.56.
