prepare for a giant PIA when installing them, top is no prob, but compressing the shock to get into the bottom is really hard for gas shocks, liquid is easier, when we did my buddy's ram with procomps we ended up cheating and bolting the top in, then putting the bottom underneath the jack to get it up into place

 

I usually pull all the wheels when I put on new shocks to checks all the bearings, brakes, brake lines, etc. I also started spraying the truck down today with PBblaster, make things a little easier when I have to remove the shocks.
