Sorry I forgot to answer your first question completely. Yes mine are the Blue/Yellow Bilsteins Part number BE5-2549 front and BE5-2550 rear, they are made for the 2500 and 3500 Dodge. I am sure you could get away with just replacing the fronts and then decide later on the need to replace the rears. I would buy them at Auto Zone so you don't have to pay twice for shipping if later you decide you need to replace the rears. I only saved $10. 00 ordering over the internet versus buying them at Auto Zone. Was not really worth the 3 day delay that came with the internet order, much less if there had been any problem with the shocks and I would of had to ship them back. I found out that Auto Zone carried them after I had ordered them from SHOX.com, other wise I would have gone to Auto Zone. Good luck, if you just replace the fronts let us know how that works out since you don't tow or haul it might ride just fine, if not you just go back and install new rear shocks. With shocks you just can have one new shock on the right side of the truck and a old one on the left, they have to be installed as pairs.
