Do not buy Old Man Emu if you plan on med to heavy offroading. it will sag back down.
?? :sure:
In my experience OME is one of the more durable suspensions available. If you've got sag (meaning: "the suspension's fallen and it can't get up") then you've got a warranty claim. ARB is phenomenal when it comes to honouring OME warranty claims.
Obviously, if you buy the JC1B's and the 930's, then add 250 lbs of bumper/winch/tire-carrier, cram recovery gear/tools in the back for another 150 lbs, and then proceed to flex like mad, you're going to stress the suspension.
The spring-rate of the 930/JC1B combo is designed for the weight of the stock, or near stock, XJ and isn't going to be up to the task. OME offers higher spring-rates for heavier demands (including the full-length JCXL add-a-leaf), though RE is more economical once you get to finagling around trying to get OME to 4.5' or 5" of suspension lift.
For the kind of wheeling that many people are going to expose a '99 XJ to, the 2" OME suspension, with 30x9.5" tires would be ideal. If you want longevity and good re-sale, then this new suspension is, IMO, better than the factory design and will increase the value of the vehicle. Once you get into suspension lifts over 3" in a '99 you're also into the Jeep money-pit syndrome, with the need for an SYE, 31" tires (with the extra weight & wear/tear/gas mileage issues), quick-wearing brakes, etc etc.
