Just called Bilstein. Pronounced 'billstine' BTW. I always called them 'billsteen'.
I had to wait until today because all the help was at the Baja 1000. So the PNs for a 93-98 ZJ with 3" lift (2.5"-3.5" should be ok) are
rear BE5-A463-H5 (need different lower mount bushing sleeve, see below)
The lengths are approximately 24.5" extended and 15" compressed, which equates to a respectable 9.5" of travel. If you haven't converted the rear lower shock mounts to 1/2" hardware (highly recommended), you will need a 12mm bushing sleeve for each rear shock. Sorry, I failed to write down the PN for the bushing sleeve, but Bilstein has it. I'd say just go buy some 1/2" grade 8 hardware and go that route instead.
I am verifying the PNs and shock lengths with Kolak by email. I'll post back with his reply, or maybe he will.
