I am about to get a lift kit for my 98 tj sport, i hear a lot that you have to get a new driveshaft with 4 inches and over of lift, is this true, i wont be doing much offroading, just a little bit of muding here and there.

Yup. At the VERY least, you need to be able to rotate your rear axle for proper pinion angle meaning you need adjustable upper arms at a minimum, and IMHO, an SYE is an absolute must for any lifted TJ. (Because you can't rotate the drivetrain down to get matching angles on the U-joints, an SYE is helpful.)

The technical advice you get from me here is worth exactly what you paid me for it. Warranty issues will be reimbursed at double what you paid me for the advice.

Every TJ is different, but the DS on a TJ is already short. You will be at the threshold of the working limit for the u-joints. You might get away with a motor mount lift, low profile transmission mount, and a transfer case drop to prevent you from getting vibes.

Why do you want a 4" lift? What are your plans? There is a lot that goes into a 4" lift to get it done right, and if you aren't willing to do a sye, I wonder if you are willing to get the rest of the necessary things done.

It's not about the "abuse" a shaft takes when it's off-road, it's about driveline angles and their effects on universal joints.

I never have and never had any problems.I always did a MML and a slight t case drop to get rid of all vibes.You can do a 3" lift and 1" BL and run 35's.I've done that too.4" lift and 33's.

What is the most amount of lift that i could get without doing anything major to the drivetrain? I am in high school so i'm trying to make my tj look good without spending to much money lol, just trying to spend enough for a lift, rims, and tires.

You could do 2-3" suspension lift and a 1.25" BL for 33's.
2" BB and 1" BL here with 33's.

MCE Fenders (Modern Classic Enterprises - $160)
33" Goodyear Wrangler Duratrac (high quality, long lasting, quiet, aggressive, pretty cheap tires)
Maybe a small 2" lift or 2" lift and a 1" body lift.

So i take it that it is a good lift, just not the shocks. What shocks would be best? What brand would you guys suggest on a 2.5 or 3 inch lift?

For every 1 person who doesn't like the shocks,there are 10 that say they're as good as stock or better.Mine rode just fine.
