New wrangler TJ owner and I will need advice!!

Decided to sell my Mercedes 2006 ml350 and bought a 1999 wrangler with a sbc 350 with a turbo 350 auto trans. I'm taking over someone else's project. my first problem is the axel gearing, the motor is doing around 3k at free way speed. I would like to get it down to about 15 or 18k at 65 mph. I also have to say I am running 33" tires. I believe the transfer Cases are original. The jeep was born a 4 cylinder and standard trans. I believe I would have to change the ring and pinion gears but to what?

Try this to figure out what gears you want
If it was born a 4 cylinder 5 speed you have 4:11 rear and 4:10 front gears or 3.73 if it was auto if they haven't already been changed

BTW Welcome to the form
