Pretty straight forward swap. I believe all you need is a floor jack to place under the end of the spring to take the tension off....then swap the two bolts.

You may want to take some measurements prior to the bolt R&R so you can monitor your height adjustments.

This is the bolt you'll be swappin' out

It took me maybe 1hr to do both sides but I jacked the frame and removed the rear wheel before jacking the spring tip to swap bolts.

Measure ride height at each rear mid wheel well point, measure the bolt length at each wheel and set the new bolt lengths to lower and level ride height.

Drive the car to allow the suspension to settle and check the ride height. Adjust till your are satisfied.

Soon after lowering the rear, get a 4-wheel alignment.

I did not jack the car up multiple times I just put a wood block on my floor jack and lifted the spring. Then I pulled the tire for more clearance so I could to clean up the suspension while I was down there. This is a simple job and should take less than an hour. The front is more time consuming.

You have to put the car on stands to remove the wheels, but you don't have to do either...ala boatguy...to lift the spring end and access the bolt.

To make the car lower you use a longer bolt. About 9" should do the trick.
