Question for Hummer Pro's
so, I had a little lift done on my ride a while ago. I had 37.5 toyo open country's put on with 20's. I did not want to spend the extra money to have it regeared, so I tried to just roll with it. Obviously, this created a little problem for highway driving, as my ride usually downshifts to push the speed limit and stays in 3rd when highway driving, ony shifting into 4th when it is straight or downhill. I am trying to get it to drive on freeways better without chnging the gearing, so here is my question for everyone:
I have put a chip in it, and this has helped a little, but it is so close to having enough power to get to 4th and just stay there.
Would it help if I was to add an intake and a performance exhaust in this situation? I just need there to be enough power so that my ride can push 4th gear on the highway, but I don't know enough about intakes or exhausts to say that this could give me the little extra I need without having to regear. Please give me some advice if you know about this....
Thanks!

Re: Question for Hummer Pro's
a good intake and exhaust will run you more than the gears if you can install'em yourself. Gonna be spending even more money if you do the intake and exhaust and it still doesn't get you were you want. You know hands down gears will work... I put an intake on my ride and the engine got louder and it lost some torque.
I'm in the same boat, I have a magnacharger waiting to be installing in my garage and I'm still re-gearing.

When I did my first H2, I did gears at first to make up for the larger tires... It helped but not enough. Later I installed a supercharger.
My present SUT has 37's on it with no gears and no supercharger. It's gutless.
Soooo, this weekend I installed a supercharger. Haven't driven it yet since I don't have the correct fuel block but I'm gonna try this way without gears this time.
I'll let ya know how it works.

Re: Question for Hummer Pro's
Thanks boys, looks like I am going to need to regear since I don't have $6 - $7 grand laying around.

This will not work. I have one of mine that is supercharged and the problem will again appear as your out of the power band of the supercharger with the tire size combination, it will only lead to more issues. REGEARING is your solution.

Re: Question for Hummer Pro's
Don't forget superchargers are known to blow transmissions on h2s all day long...

Re: Question for Hummer Pro's
 with Crush
If your doing the tires the right and easiest way to go is supercharger and gears!
One added bonus is the external transmission oil cooler which is cheap insurance for the mods ( my tranny temp stays at 160 all day long with the supercharger)
