03 Sport.
I had the revtek spacer lift installed. Also installed rancho shocks on the rear (stock struts on front). I was not happy with the level. The Jeep looked low in the rear. So ... I replaced the 2 inch revtek spacer on the rear with a 2.5 inch daystar spacer. That brought it just about level, but not quite. So ... just this past weekend, I added another upper coil spring isolator pad (stock rubber pad) to each side in the rear. Now, the level is perfect. For some reason, I think the 2 inch revtek lifted more like 2.5 in the front and that is why I had to change the rear. Anyway, I'm very happy with the results and the ride is much better over bumps and dips at speed now. A side benifit was that whereas it used to pull to the right, the Jeep tracks straight after the alignment required by lifting.
I got the daystar spacer and rancho shocks at ALL J Products
