Just got a set put on they did drop it about 1.5 inches.

They are avalable from www.airbagit.com

You will have to specify which ones you need short or long. Mine took the long ones.

Install wasnt very good. The upper part of the shackle wasnt wide enough to go over the leaf, sothat had to be fixed, and the lower part wasnt wide enough so I had to stack washers to take up the slack. Over all they did what they were supposed to do.

Hope this helps anyone that was wanting to get a set or couldnt find a set to lower the back of there 2500 truck.
