Installing drop shackles is a pretty simple process that anyone with basic mechanical skills can do. The first thing you need to do is jack up your vehicle and support it on jack stands. Once your vehicle is safely supported, you'll need to remove the rear shocks. To do this, first remove the top shock mount bolts, then the bottom bolts. With the shocks out of the way, you can now remove the factory shackles.
To install the drop shackles, you'll need to start by attaching the top bolt to the shackle. Once the top bolt is in place, you can then attach the bottom bolt. With both bolts in place, you can now install the rear shocks. Once the shocks are installed, you can lower your vehicle off the jack stands and you're done!
