If you look on some of the diesel forums for "CaryT" he has some recommendations. Basically, X-code springs (from an F250) in the front, modified B-code springs (from an F250/350) in the rear and specially valved Bilstein 5100's all the way around. The modification to the rear B-code spring pack is to reuse the Excursion spring spacers (the truck springs just have a small, flat piece of foil/metal inbetween them), remove the top overload spring from the B-code pack and then add the smallest two Excursion springs back to the pack. The other piece is to add a rear sway bar or to upgrade the current rear sway bar if you already have one. Folks generally choose either the aftermarket Hellwig piece or the 30mm F250/350 piece.

For my Ex, I'm waiting for my V/B-codes to come it and I have the Bilsteins from CaryT already. I can't add the Hellwig bar because it doesn't fit with my undercarriege supplemental fuel tank. So, I'm hoping the Ford 30mm piece will fit because it mounts to the axle differently.

Other folks swear by adding traction bars or radius rods to the rear suspension. Other folks have installed the Timbren overload pieces (look like oversized bump stops) and are very happy.

Good luck! Hope this gives you some ideas.
