YJ lines will work perfectly fine for your build. I'm running RE 4.5" springs and used them (front and rear) on mine. I bought them from Rock Auto (Bendix front and Raybestos rear) and got them pretty cheap. There is absolutely nothing wrong with a stock rubber line.

The only hiccup I ran into was that I had to remove a little bit of material from my driver side caliper to get a good seal. The caliper end on the YJ hose was slightly larger than the XJ hose and wouldn't fit flush without a little help. After that, I had no leaks and they work great. Also, they are significantly cheaper than the braided lines....which is nice.

 

do you have part numbers for the front and rear lines?

 

From the RockAuto site:

F/L-Bendix 78122-$10.84
F/R-Bendix 78121-$10.84
Rear-Raybestos BH38845-$9.27

There are many more listed on the site, but these are the ones I used. Search for a '95 Wrangler.

 

YJ lines will work front and back. I use them and have a 4.5" lift. Plenty of room.
