I've got a 2000 Jeep Sahara with 4" ProComp suspention lift, and 33" ProComp XTreme M/T's, I would like to put 35" tire's on but already my 33's are scraping. I've thought about a 2" as well as a 3" body lift to get the tires some extra room. Should I put a 2" or 3" body lift? And, should I stick with the 33"'s or would I be able to clear 35"'s with the body lift?




Also, fuel prices are killing me, I bought a Tornado Performance Booster, hoping that it will bring down my fuel usage. Does anybody have any other ideas to help me save on fuel?

Thanks Everyone!

with 4" lift you should only need a 1" Body Lift.

What you can do is take the factory sprong Isolators out of the front of your jeep and move them to the rear (.75" lift for the rear) Replace the factory Isaolater with a 2" Poly spacer (1.25 lift over factory in front) the reason it is 1.25" is because the factory isolater that was removed is 3/4"
Add 1" BL and you effectivly have 6" lift and more than enough room for propery bump stopped 35's

This?

Haha, throw it away. Change your driving habits. The tornado is proven to REDUCE MPG... lol

Crazy4ink posted something here (http://www.militaryjeepers.com/community/showthread.php?t=2093) about the fitch fuel catalyst system. He listed some of the numbers that he got with the system. It does not seem like a huge 10mpg imporvement, but over time I am sure that it would pay for itself.

http://www.militaryjeepers.com/community/showthread.php?t=2093



If I get 10 MPG now, at 4 bucks a gallon, it would cost about 800 dollars to drive 2000 miles.

If the fitch fuel catalyst increases the MPG by 2,3, or 4 MPG, then my numbers should look like below for 2000 miles a year.

10 MPG - 4 Bucks Per Gallon - 2000 Miles - $800
11 MPG - 4 Bucks Per Gallon - 2000 Miles - $727 (Two year savings of 146)
12 MPG - 4 Bucks Per Gallon - 2000 Miles - $666 (Two year savings of 268)
13 MPG - 4 Bucks Per Gallon - 2000 Miles - $615 (Two year savings of 370)
14 MPG - 4 Bucks Per Gallon - 2000 Miles - $571 (Two year savings of 458)

So, for $160, even a 1 MPG increase would almost pay for the system in 2 years, and definately in 3. It needs no maintainance until 5 years, so if you got the fitch fuel catalyst, made sure your tires were aligned properly and inflated to the correct tire pressure using the chalk test, then you should see some improvements.

I cannot remember where I read it, but they said that drivers that do not drive aggresivy save 37% in fuel usage. Just take it slow and easy and do what you can do and you will be allright.

I know someone here that bought a daily driver to save on gas. If his jeep got 10MPG, he would be paying about $800 a year in gas to drive 2000 miles. If the DD he just bought got 23 MPG, then it would cost him $347 in gas for the year. That means that it would take him about 5 years to save enough money in gas to cover the costs of buying the daily driver if gas were to stay at 4 bucks a gallon.

I run a Fitch catalyst in my Harley and have had good results. I plan to add it to the TJ...just haven't gotten around to it. They have a good product.

I am thinking of getting one, but have not even installed the gas tank skid plate because it means messing with the fuel lines. Kind of nervous about that.

I want to get one from crazy4ink and may get the nuts to do so this week.

Almost 4% on HP and torque on the dyno from being able to tune it better with more consistent fuel, and about 2 1/2 to 3 miles per gallon increase.

Well I guess it dont matter with my Jeeps. I get the same mileage from my Jeep with 4.88's and 35's as my wife gets with her Jeep with 4.56's and 33's. They both get 13+ around town and 15+ on the freeway.

I was getting 16-18mpg with the CJ, until I replaced the 2 stage power valve (10.5/6.5) in the carb (MC2100) with a single stage (8.5), now I'm getting 12-14mpg.

Time to put the 2 stage power valve back in! I was going for better performance (with the single stage), but it's not really noticable on the low end, while wheeling.


Tune ups help, and proper tire inflation along with good driving habits all improve milage.

Since my CJ can get 15+ with 33'' tires, and my '02 F150 gets 12 empty, less than 10 towing, I'll be driving the CJ alot more! I'm just bummed about that.:D

My Jeep is a primary vehicle. I know cold air intakes improve HP, but do they improve fuel economy?

I've read about the use of hydrogen in tires improving the consistancy of tire pressure, thus improving fuel economy. Do you need special stems/tires to do it with, or will any old tire take the "H"?

Fitch installation on a TJ, XJ, WJ and ZJ are all done under-hood. Where the OEM line connects to the fuel injection rail; you pull that off (the Fitch comes with the disconnect tool), plug the OEM style connector of the Fitch to the feed line, screw the other end to the Fitch. From the other end of the Fitch, plug that end on to your fuel rail. All OEM fittings and will take you about 10 mins total to install.

You don't need special stems or tires to run hydrogen in them.....
The only difference between running regular air and running hydrogen is that the hydrogen tends to not leak out as quickly as the air. If you have to pay more to put hydrogen in your tires than regular air, you're wasting your money. Just keep an eye on your tire pressure.

get a geo metro and park the jeep and put 35s on it and call it good
