My local dealer does not seem to have a clear answer on if F4-BE5-2549-HO(front) and F4-B46-1908-H1 (rear) are the 5100 series bilstein shocks for O2 4x4 2500. I have heard good things about the 5100 series. It seems it may only be for "lifted trucks". I am just not sure but getting ready to put order in for these shocks. Does anybody have info? Thanks

 

I think the 5100's will work at the stock hight. JDGnut is running them with no problems.
BE5-6681-H5 Front
BE5-6682-H5 Rear

I'm running them on my truck (stock ride height) without issue.

 

I'm running the rear BE5-6682-H5 and have Skyjacker springs with BE5-6681-H5 up front, no probs
