This is a real easy one however if you have never done the swap yourself save yourself money and get under there and do it. Its Easy...
I found the hardest part of doing the swap is getting the new shock brackets through the grommet on the new shock. It takes some determination despite it looking like your going to force a square peg through a round hole. And make sure youre not installing your shocks upside down!!!
First jack up the truck and place jack stands under the frame just in-front of the rear Leaf shackle, like Charlie demonstrates in his Shackle swap picture.
Then remove the lower bolt holding the shock and let it hang.
Second, loosen the upper bolts holding the upper rod to the frame. The right side is a breeze but the driver side clearance issue will slow you down a bit.
Next, if you want to save and re-use the bolts from the original hangers pull our your BFH and knock them back out. If yours are like mine, they will give you a run for your money. I ended up trashing mine and I would reccomend replacing them with either a grade 5 or grade 8 bolt. Nothing less.
Now to re-install its as easy. Have a buddy help you hold up the new shock so you can work with both hands and tighten up the top bracket to the frame again with your old, or new bolts. Once you have secured the top, its real easy to align the lower bracket and re-install the bolt. Thats it! Finished install of ProComp ES3000's.
Notice, after my install you can see that my leaf springs are pretty worn out and need replacing, the good indicator is that the boot on my new shocks are pretty compressed. If you run into this problem, do as I am, beef up those springs.
Hope this helps.
This is my 99' !!!!!!
