My first Jeep, help.....

Make sure it's got a big tranny cooler for the towing or you'll kill the tranny.

I would ditch the ES3000s all together and go for a better shock. If you also get BPEs (bar pin eliminators) you will avoid having the same problem in the future. the bar pin design makes it so that you ruin that bushing easily. You could throw poly bushings in there if you're on a budget though.

As for the springs, I would go with a 3" leaf pack from rusty's offroad. You can get a heavier spring rate one, just ask them for it. Others may say go with RE, it's a matter of preference, but basically IMO these are the only two decently priced good spring packs there are in the 3" range. OME has a 3" pack too, which is probalby superior to both, but you have to have deep pockets for those things. Their shocks are also probalby the best for on road ride quality, but again, not cheap. Other manufacturers that have quality springs don't make 3" packs AFAIK. Good luck.
