Bilstein
I recently replaced my original shocks, '93 XJ 140K, with a Bilstien set. My Jeep is stock so I bought the set rated for stock replacement, not off road.
I also rebuilt the sway bar at that time. Of course, the change was immediate. There's a lot less rock, left to right, and although I expected a worse ride over bumpy city streets, it's really not worse.
It's a stiffer ride, but I believe the suspension is doing a better job of dispersing the energy produced by ruts and bumps.
I paid about $50 per unit. Are there better gas shocks out there? Probably so.
And of course I'm no expert on this topic, just a guy trying to take his Jeep to its 20-year anniversary. Can't wait till the engine goes out so we can consummate the relationship!
