    Ok im about to the point I need shocks for the build up.
    Here is the specs so far 88 K5 6inch ft springs rear ORD 4inch flip with 2.5 rear springs corp 10 bolt 8 lug and 14 bolt w/detroit and 37/12.50/16. I bought the 1980 Ford ft shock towers and getting the Missouri Offroad rear shock bracket with weld in axle mounts. So the question is what kind of shocks do i need I thought about 5012 or 9012 or is there a better shock out there for this application? also what is the difference be tween the 5012 9012 other than 9012's being adjustable? I'm not going to run a ft swaybar.
    Any input would realy help
    Thanks,
    Bo

    RS5000's are twin tube, I think, I know RS9000's are triple tube and adjustable. If you're not running a sway bar, get the 9012 shocks, because you can harden them for street driving and soften them for trail use.

    That is the primary difference, which is a very substantial difference at that. The RS5000's are only slightly better than rebar, whereas the 9000's can be run from ultra soft to 5000-stiff. Rancho also makes the RS9000X, which is a 9-position adjustable shock. Pro Comp makes the MX-6, which is a 6 way adjustable shock, and a very good one at that. The adjustables can also be mounted with the shock body on top or bottom, while the 5000 can only be mounted with the body on the bottom. Don'trule out the Bilstien 5100 series either, which are superior shocks themselves.

    Thanks for the reply. another stupid question. Do the 5012 &9012 do they come in differnt sizes for lifts or are they
    one size only? The reason I ask is I want to do the rear
    shocks like Steve's but reading the other posts some are saying there shocks are to long now im getting confused on
    how to do the rear shock setup.

    The 5012's & 9012's are a specific shock. They are (were) the longest shock available from Rancho for a long time. I believe they now offer a longer shock though. I don't think that the RS9000 series is available anymore. I believe that Rancho has switched production to the RS9000X the 9 way ajustable. When I bought the RS9000's for my Dads F350 a few months back they were the last set of RS9000's that weren't the X that the shop had.

    The 5012 and 9012 are actually (application specific) for the rear of a Ford F250/350 4x4 99-up. The reason most use them is because of the compressed (19") and extended (32.250") dimensions, and the 13.250 inches of corresponding travel. You will need to do some research on your truck's rear suspension/mounting locations (i.e. are you mounting them stock, like this- /\, or otherwise), and then see what you need. Things like droop, compression, mounting location, etc. will likely affect the choice of shock for the rear.

    Yes, they do. I don't have my Rancho catalog in front of me, but I can look up the part #'s if anyone really needs to know. I believe they offer 3 or 4 shocks that have no application, they are just different dimensions/travel for custom mounting.
