First time post on this forum, can't believe it took this long to find it! GREAT resource...love the helpful and civil interactions here (unlike some other forums which I won't name!)
So I appreciate the info above on the shocks for my truck, but just wanted to clarify if possible that the OP is referring to the OEM rear air assist auto leveling setup, NOT the full air suspension like on the 2500s? Not clear, but I am looking for new Bilsteins (4600 or 5100) for my truck '15 3500 dually 4x4 with rear air leveling (stock height). The 4600 Bilsteins I found seemed like they would work (24-238526 fr. and 24-238533 rr) but the guy at the shop says his info shows the rears won't work. His guy at Bilstein says the rear ones "won't fit" but apparently no explanation as to why?
Anyone know for certain which ones I need...the Bilstein website offers no help that I can find. Thanks!
