Monroe air shocks

Step 1: Admit that your plan is 'tarded.
Step 2: Take the rear springs off. It's easy. You don't even have to pull the axle. Just a jack and stands at a minimum.
Step 3: Steal another car and take your springs to a leaf spring shop.
Step 4: Tell the leaf spring shop you're a recovering 'tard and need to increase the rear ride height by "X" amount of inches.
Step 5: Drink Mountain Dew while spring shop does their thing.
Step 6: Go home, turn back the clock, reinstall newly modified springs.
Step 6a: Ditch stolen car. It was probably a Kia anyway.
Step 7: Pull 'tarded pickup shocks, install proper shocks, possibly longer ones depending on "X" from Step 4. Sell 'tarded pickup shocks to some 'tard. You don't need them because you're not 'tarded any more.
Step 8: Realize that height and load are controlled by springs, not shocks. Shocks are damping only.

1977 called, and they want their ignorant air shocks returned to them.
