Lowering

I just got a used truck which was lowered before I bought it. When I went to look at it, the dealer raised it to stock. I was okay with that since I thought I would be able to lower it myself. I don't see any springs under the truck but it does have shocks which I believe that makes it look high. It also has leaf springs. My question is, how will I be able to lower the truck? Can I make those shocks shorter? I would appreciate the help. Also does the truck need shocks without springs?

The shock are new and shiny. So in order to lower it there are torsion bars to adjust. So the shocks do not have any " say " on the height of the truck. I will try to get good pictures to help with my problem. I did see the springs in the front but the back is higher

I would keep this really simple as there are many kits out there that will lower this vehicle for you but go with one that has spring blocks for the rear and a new spring a shock kit for the front.

You have coil springs in the front and leaf in the rear and these are very easy to lower using a kit but there are many wrong ways to do it like cutting a coil spring out of the front which if not done correctly will cause many issues.

So just replacing the coils and shocks up front and then blocks in the rear is the easiest and cheapest way to go. The blocks in the rear simply cause the frame to sit higher compared to the suspension and this causes the suspension to tuck up into the body of the vehicle.

Please see the picture below of one that I found quickly on the internet. These can be installed in a couple hours in your driveway so here are a couple of guides that will help with doing this safely:
