Right, so back to my original question. If I have the FX4, don't I already have a rear block? So would the longer shock be the better option?
OK, sorry I missed exactly what your are asking. I had one of the first sets and tested these for Rancho. I have the FX4 and the shorter Rancho rear shock. I did note to them that it was about an inch shorter at full extension than my stock FX4 shock but I did not think it would be an issue, at least for me. Now that they have a slightly longer version I would probably go with it if I had the choice.
So, it seems the best option would be to use a 3" block in the rear with the 287's to get a nice level ride and pretty good off-road capability? What blocks are you guys using?

Thanks! That was the info I was looking for. I just talked to my installer (truck's going in tomorrow) and he had ordered the -384, but when I told him what you said he said he'd get the -287 as well and see which one fit better. I'll let you guys know after tomorrow which he went with.
I ordered the 287 and the 384 to compare. I have the fx4 package and the 384 was 1" shorter. The 287 was 7/8" longer at full extention than the fx4. Since I added 1.25" of lift in the back, I went with the 287.
Just got the truck back from the installer. They ended up going w/ the -287. Said it could've gone either way stock, but if I ended up getting a bigger block to put some rake back in or installing air springs to help with towing down the line, the -287 would probably be better, so he used that one.

Looks just about right now!
Rancho Quicklift w/ BFG KO2 285/65-20s
Looks good! How do you like the ride & handling so far?
A little early to tell, and I did the tires at the same time, but first impressions is that body roll is reduced. I also drove over some railroad tracks a few times and, though I could obviously still feel them, the initial 'hit' didn't seem as harsh as w/ stock. The tires are set at 62psi and the installer set the shocks at 5, but I clicked it back to 3 to start with.

I run all mine on setting 3 as well and haven't found a need to move them. Fwiw, I run my K02s (275/70/18) at 40PSI, 62 seems a bit high unless you're going to be towing some heavier loads. It would definitely ride rougher I would think at that higher PSI. Just something to keep in mind.
How's your tread life? My installer said he wouldn't run much less than that to preserve tread life. I was running KO2s (305/65-18) on my old truck at around 44psi. They rode OK, but after ~25k, they seemed to be wearing much more than they should be.
I just sent a question to BFG to see what they recommend as far as PSI.
