Bilstein 5100 order help

I've decided on the Bilstein 5100 series shocks for my 2011 F250. Here's my situation. I'm replacing the OEM F250 2" blocks (or spacers) with 4" ready lift blocks (which I believe is what the F350 has). I'm also adding a 2" autospring leveling kit. Bilstein and 4 Wheel Parts says the front should be part #24-186018 and the rear should be #24-186066. I'm good with the fronts but I'm unsure on the rear and this is why... On Bilsteins website it states that a F350 with no lift (which is the height that I'm after in the rear) requires part # 24-186025. Big Sarge used the 025 part number on his video.
Basically a F250 with a 2-4" rear lift requires part 24-186066 and a F350 with no requires part 24-186025

Need some help. Are the mounts different or something. Thanks

I did a similar setup.
- 4" ready lift rear blocks (F350 blocks are 3.75" tall)
- Bilstein leveling kit with front springs and shocks.
- Bilstein rear shocks

Here is the link with all the info when I did mine.

As you can see in the link above, I am running the 24-186025 on the rear.

I would give Bilstein a call and ask them directly what is the difference between the two different rear shocks......

That IS a head scratcher. I can't see why the #025 wouldn't be correct. I'd bet the #066 is the next longer shock, which would accommodate an F250 w/4" block (or a 350 w/2").
