I have those, too. Too mushy for my taste ... but they're in ... until I get sick of them ... or I break one.

 

They are a very easy repair to do. the back axle, I just crawled underneath and removed the top and bottom bolts. they should be soft enough to just pull out of their brackets.
Now, this may be common sense, but those white straps on those shocks in the pic, do not cut them until you have either the top or the bottom already bolted back in. I have seen too many people cut those straps before they were at that point, and it morphs a nice relaxing hour of work on your truck into a two hour mad hatter trip through hell .

The fronts have some more steps. I removed each front tire (after jacking the front up) to do this. If your truck is 4x4, there is a bracket on top of each shock in the engine bay. Those have to be removed. Not hard just three bolts to undo.
I did have some fitting problems with the fronts, the bottom holder had to be bent out just a hair to get the new shock to slide in.

 

hey squirrely,,,thas what im going to be running with my drop kit..are their any negative things bout these shocks i need to know??

 

they're a little stiff at first, but soften up a bit as you drive. Body roll is greatly reduced

The only negative I have is getting the damn bolts to stay tight so they don't clunk on big bumps when they loosen. maybe some high strength locktite might help that.

I really like mine, I'm not looking for a bone jarring ride or doing any wheeling.
