I am going to be putting lowering shakles on my truck. Is there any other modifications I need to to? Any bed mods? Do I have to take out the overload?

By putting on drop shackles, the pinion is tilted forward by a few more degrees. In some instances too much pinion angle can cause problems with traction, drive shaft bind, proper lubrication of the rear end, ect...

I don't think there is really anything you can do to the front hangers sort of torching them off and welding them back on in a new spot. The other option is to cut the spring perches off and weld them back on at the stock angle.

The third and most popular options is to put the drop shackles on and enjoy the new stance of your truck without anything else done. Many, many people run drop shackles alone on these trucks without any issue at all. You can just put them on and be done with it. To get a few more inches lower, you could take out the overload.

Well said. Thanks

Depending on how low you want to go.

Also, talk with a shock dealer and get the low down there.

Y do I have to remove the hitch?

Because it gets in the way of pulling out some of the shackle bolts, or at least that is what I have heard. You could cut them once they are part way out and replace them with shorter ones that you can put in from the outside and will not hit the frame I suppose.

I would recommend you do NOT install a degree shim on something that is frequently driven on the street or at high speeds.
