I have a 2007 Wrangler x and I plan on putting a teraflex 2.5" budget boost lift and upgrading my tires to 33's using my 16" rims. Right now my tires are 30" I belive.

my question is, with these 2 upgrades, will I need to change anything else or worry about problems? i heard people say stuff about the gears may need to get changed and also how far off will my speed gauge be. im not an automotive person, i work on computers for a living

please any tips or advice is appreciated

Depend's , what gears do you have now. 3.21 or 3.73. since it's an 07 mite even have 4.10's. If it's 3.21 then you mite want to regear. Then get a Procal to reset the speedo.

Recommend getting a SuperChips Flashpak.
You can correct the speedo, improve performance, plus some additional features.
The best thing I did after I went to 33's. I'm on 34's now and will probably re-gear to go to 35's.

X2 Superchips, also you can run the 35x12.5s with the 2.5" lift no problem just ordered mine last week

I'm runnin 33"s and my speedo is about 3 mph's off. It's further off the faster you go. This tire calculator will tell you about everything you need to know about changing tire size. http://www.discounttiredirect.com/di...foTireMath.jsp

dont mean to steal this post but in regards to gearing. how can one find out what gearing our jk has?

You can request a build sheet from Jeep's website. I'm almost positive this is the form you fill out. http://www.jeep.com/wccsapp/universal/J/index.jsp

X2 on the Flashpaq. I have an '07 X 6 speed with 3.21's running 285/70R17 Duratracs (33") and I have no issues, loss of power, etc. I'm currently running the 87 tune. I had better performance with the 91 tune but running 91 octane wasn't worth it $$$ wise with gas at $4 in CT.

Thanks for the feedback

another question, can i put on 1.5" wheel spacers or should i just get wider rims/tires. will that effect turning at all and will it rub against anything?
