I still have my sensors and whatnot. Did you keep the factory air shocks, or did you retrofit bags?
If you kept the factory air shocks, I'm assuming you're using a 4" drop shackle?
I do have the axle relocation brackets similar to the ones pictured.
I researched and found an aftermarket air shock with the same collapsed/extended length as the Belltech drop shocks and ran those.
They rode nice, my only complaint was if you get into a situation where there is a repetitive bounce, like when coming off of certain bridges, they were softer than I liked.
