Tell us what have been the best and worst modifications that you've done to your ZJ or WJ. The best for my ZJ has been the four inch long arm lift and the electric cooling fan swap. My ZJ looks great with the lift and rides awesome, the the operating temperature barely makes it to 200 degrees since the fan swap. The worst mod would have to be the one ton steering swap. It caused nothing but death wobble and crazy bump steer.

 

So far the best mod was the ford taurus fan & volvo relay. I also did the neon injectors. So far both have been good upgrades.

My best by far is the hid retrofit. Haven't really had a bad one yet and hopefully it stays that way

 

Worst mod would be an aftermarket sunroof. The PO had it installed. It's cool when it works, but it sucks when it doesn't.

 

I'm right there with you, I hate the fact my ZJ has a sunroof. It's the only thing I hate about my Jeep.
