I am looking to replace my coil springs on a 99 TJ. I want 4" lift springs and am considering Rubicon Express, Rockkrawler, and Old Man Emu. I currently have 2" OMEs and I am happy with the ride. The jeep is a DD and I want something that is good on the road. I want some input on the RE and Rockkrawler springs but if there is something else I am open to suggestions. Thanks.
