    I'm installing my lift and have a question on the shocks. They are procomp 3000. Should I put the piston on the top or the shock canister. The pics on the box show the piston on top but I know other brands requier the oppisite. Thanks!

    K-5- because size DOES matter!

    With the ProComp ES3000 you have to mount the piston on the top.

    I currently run mine with the piston down in the rear only because it's the only way they fit.(I have to cut and reweld new shock mounts for the 14 bolt.) Let me tell you it sucks bad. It's almost like not running shocks at all. I'm bouncing over everything. It almost seems like my rear ends comes off the ground sometimes I bounce so hard.

    To my knowledge, only Fox, King, Doetsch, and other reservoir shocks are supposed to be run piston down/body up. The only non reservoir shock I know of that can be run upside down and still be effective are Doetsch's PreRunner series.

    If the shoe fits, get another one just like it

    Esteban, I'm in the same situation. I just put in my 14 bolt and the drivers side shock canister hits the axle tube. I tried the sledge hammer and torch method. It moved a little but I'm gonna have them re-welded anyway. So it really matters if the piston is under the canister?

    What happens when the shocks are upside down is all of the hydraulic fluid runs to the bottom, and the piston just travels through an air bubble, and has little, if any damping effect.

    Yup, the shocks don't work as they should. The valving inside is made to run the right side up. So they are basically useless right now.

    I tried mounting my RS 5000's upside down and found out that they just don't work well that way...1 day of that and I switched em back.
