Regearing would be the most effective way, in terms of cost versus result. The 3.8L Jeeps are woefully undergeared straight from the factory.

Other than that, a tuner such as the Flashpaq Superchips, Hypertech, etc, depending on your YM.

If you've got the coin, a hemi or a supercharger.

Someone will recommend a cold air intake, but I won't.

Look into gearing first to get the most bang for the buck. If you are still looking for power, look at RIPP, Sprintex, or Magnuson superchargers. The Hemi conversion is what most people would like, but they are very expensive.

For a gear change, you want a shop that specializes in them, ideally. Some of the better 4x4 shops could handle it. The reason for this is so you can maintain warranties from both the gear mfr and the shop that installs em.

Anyway, you want a Master install kit. Even an experienced gear tech can end up trashing your pinion nut, etc, while removing your stock gears.

Cost is usually ~ $1500, so obviously you only wanna do it once. Best bet is to settle on a tire size for your rig, since that will determine how low you wanna go with gears (along with other factors such as auto/manual, the type of terrain you drive in, etc), and go from there.

All of this plus, if you ever want to install lockers or LSD, now is the time.

To give you an idea of what goes into determining what gear would be best for your particular situation, check out this thread, starting on page 2 with a post by Yella (page 1 deals with the pentastar Jeeps).

Yella was trying to figure out which gears would suit his Jeep...believe he finally settled on 4.88.

Want 35s dont want to REGEAR ??

^^ Yup, great point. Might as well spring for it all at one time, while the guts are exposed.

Research is half the fun of doing Jeep mods. At least you are trying to learn before you jump in with both feet.
