No power

I just bought a 2008 Wrangler Unlimited. It has a 2.5" Teraflex lift with 285/65 r18 tires. I love the Jeep, the only problem I am having is it won't pull itself in overdrive. I haven't figured out what gear ratio it is but I am thinking it is the 3 21. What are my best options for gaining more power, lower gears, chip the engine, or what?

Somebody help please......

Regear. There are many that have 3.73 and 4.10 gears with that size tire and no problems but the guys with 3.21's generally hate life with bigger tires especially with the auto tranny. If you will never get tires bigger than 33" throw some 4.10's in and you will grin ear to ear. If you plan on 35's or larger might want to consider 4.56-4.88. There is a lot to read on the forums pro and con about gear selection and differing opinions. Programmers and so called bolt on power adders don't make huge differences. Look some of the tests done and at low rpms where you spend most of the time will be very small gains. You can spend $2000 on building power and still wish you had lower gears.

Thanks, where is the best place to buy gear sets. I will probably go with the 4 10. Should I do some type of lockers while I am in changing the gears.

The best place has many factors; price, shipping, install etc.. You will have to shop around. 4.10's are sometimes much more expensive so you'll have to look hard. If your going to have lockers eventually, I would do them all at once. Don't want to pay twice for the install.
