Air shocks are great for people who don't carry the same amount of weight all the time and want to adjust their shocks.

I bought a set of air shocks from my local Napa for around $75. They are actually Monroe shocks re-branded for Napa. They are fairly easy to install as well.

1. Remove spare tire

2. Jack up the rear of truck and put jack stands under the frame, not the axle.

3. Remove the old shocks. This can be a little tricky if your old shocks are original or very old. The bottom bolt is the hardest. I ended up heating it up with a torch and using a hammer, screwdriver and channel locks to finally get it loose. The upper mount simply unbolts from the crossmember.

4. After you have the old shocks out its time to install the new ones. The shocks that I got did not have the upper dog-bone to mount to the crossmember. I ended up cutting some threaded rod to length and welding it to the crossmember to make the shock mount.

5. Bolt up the bottom mount using the original bolts.

6. Now you need to find a place to run the air lines. I ran mine up towards the body and over to the drivers side bumper.

7. Drill the hole for the fill valve and mount it. http://mistercmk.com/album/albums/us...2/DSC01055.JPG

8. Hook up the air lines making sure to not overtighten the fittings as the WILL leak if overtightened. It just needs to be snug.

9. Inflate the shocks to at least 20psi.

10. Lower truck and re-install the spare tire.

Thats all there is to it. I usually keep my shocks at 35psi when the truck is emtpy. Its pretty easy to adjust the air pressure depending on your load. They do need at least 20psi all the time to keep from damaging the air bladder and can handle up to 150psi for heavy loads.
