Leave stock,keep up on maintenance and it will last a long time.
The 3.7 is not a engine you can really mod and there is almost zero aftermarket stuff for it.

Yes do all required maintenance
Plugs changed at least every 30,000 miles ( NGK coppers )
Coolant system flushed and new HOAT coolant
Air pressure kept up where it should be
clean paper air filter
Thats about it, CAIs, etc do not work,
Its a Jeep, runs very well for what its suppose to do
Unless you want to tear it down, custom ground cams. head work, computer reprogrammed, and many other things, you are done
Trust me, after 14 years of building these KJs , thats the best you can do

Contrary to my snarky (but justified) comment in your other, duplicate thread, my legit answer to this is: Don't.
You've seen this echoed. It's meant to be a well-maintained medium duty, long lasting platform. A Jeep with nice amenities that you can daily drive, take to the trails and off road, get some work done then go get the kids from school.
Do all your maintenance, do it often, repair broken items immediately before they cascade into a list of issues as long as your arm.
Don't go changing this or that, things designed by people smarter than most of us and designed that way for a reason (other than the cost-saving reasons). These KJ's have been on the road now for 16 years, and they do well. They do BETTER when they're kept in stock, as-built condition.
I'm not excluding improvements like proper spring lift kits, swapping to 4.10 axles from the 4cyls, or things like that... but as far as drive train goes, the only thing I can think of that actually helps is improving the transmission cooler arrangement. And depending on what you do with the KJ, that isn't even universally 100% needed.
