Coil spring size and brand on a TJ?

[BigClay]

I have no idea what brand or length springs are on my 98 TJ. I am thinking they are either 3" or 4" lift, because I am running 34" tall tires. Either way the springs have seen better days and need to be replaced.

To run 33" to 35" tires on TJ, what is a good spring lift height? Also what brand springs, RE, BDS, or?

RC 2-1/2"s and cut the fenders.

I ran 4 inch rough country on mine and ran both 33s and later 35's. The 35's would rub a little under full compression.
