Definitely avoid the dual stabilizer setups, they are not needed for even 35's or 37's and besides, all they do is make the power steering system work harder. That added work the PS system would have to do can, on a hot day when on a tight twisty trail, be enough to cause the PS system to get hot which makes steering harder, or even make the PS fluid boil over.
Most steering stablizers are all pretty much the same but the hardware kits supplied with them are not. Your TJ requires a specific tapered bolt to replace the one that is permanently attached to the OE stabilizer. So make sure to buy a kit that is specifically for the Wrangler to assure yourself you'll get that tapered bolt. Rancho is fine, so is Skyjacker, OME, Doetsch Tech, Rubicon Experess, etc.
