Drop Shackle Install (2015 Chevy 4x4 Duramax) 

The knuckles on the leaf springs will "squeak" against the seam if you don't flatten it. You'll need to cut a bit of the seam (I used a rotary cutting disc that had a decent reach) and then use a hammer and a punch to flatten it against the bed. Give it a bit of paint to prevent rust when complete. Also, I didn't need to remove the hitch.

Why pull the hitch would of saved more time to leave I changed mine and didn’t have to remove the hitch

WHERE DID YOU GET THE SHACKLES !!!!!! ???????

That frame looks so much older then 2015!

Where did u get the drop shackles? What brand are they?

That trucks only 4 years old and the frame is starting to rust. They dont make anything to last anymore. You should make a undercoating video in the future.

Do you happen to have the link to those shackles or part number or brand to them ?? Thanks in advance

How did u bend that pinch weld

Heads up the floor jacks you used are now currently under a recall at harbor freight just went in to hand mine back for a gift certificate of equal price.

Do you HAVE to take the hitch off to do this?

Wondering what brand you used. Need to do my 2019

Brilliant team work, Justin and Caleb, I believe. Keep it up. That rust must be caused by the salt used on icey roads. Must do something about it while you still can.

Link to shackles?

I have a '15 2500hd and installed the same shackles. Looks great. Curious if you installed bags for towing to counter the sag. I'm having trouble and seeing mixed reviews on bags fitting that are made for this truck's factory height.

Yall did that much harder then what it had to be

did you guys need to return the bolts to a specific torque when tightened?

so did you guys happen to just install the drop shackle in the back and keep the front stock or add leveling kit to the front with the drop shackle. I have a 19 Duramax and want to level the front 2" and drop the back 2" baby squat. but like the video!!!!
