I would look into f-o-a shocks. I had them im my toyota prerunner and now in my jeep and I love them. They are a 2.5 shock they have resevoir, piggybacks, emulsions, coilover etc. They have a High Pressure cast shock ends with cast in spherical bearings, revalvable and rebuildable piston/shim arrangement plus our hardened chrome 7/8 shaft. You can upgrade to Get Viton seals and an extra heavy duty piston wear band for temps up to 400 degrees. The best thing is they are $200-250 each you cant beat that for a 2.5 coilover or resevoir anywhere. Check them out
