My wife bought me the djm shackles off ebay for Christmas. I haven't seen any 2" ones for the 02+ 1500's only the 1 1/2. I got an honest 1 1/2 drop in rear bumper height measured on the shop floor before and after. the 02+ 1500 uses a shorter shackle to go lower so I don't know how you could fit a 2" in there. Make sure you aren't getting a shackle for the 94-01 which also fits the 02 2500. those use a longer shackle to go lower. (also fits 88-06 chevy and 92-96 ford)

Did you use the DJM drop shackles off ebay or sportstruck? It says you might have to modify to fit and the drop is only 1/2 to 1 1/2. How much drop did you get?? I found 2" drop shackles on ebay. Might use those.

update on the progress--i have now installed the tonneau cover, k&n intake kit, and lowering shackles. more to come.

no hacking it up, this is my new daily driver.

clean truck. those plans sound cool too... not going to hack it up.
