i think it was a hotchkis kit I had on my truck for a bit but it was too rough for my liking. It had new coils and leaf springs.
it largely depends on how low you wanna go. I ended up using 2" drop spindles with stock springs (do a search on them, theres some issues with one of the castle nuts and wheel clearance but it can be dealt with, along with grinding down the steering stops or youll be hating life with the reduced turn radius). I used drop shackles in the rear with stock leaf springs and was mostly happy with it.
My buddy did the DJM lowering control arms for the front with belltech hangers for the rear with a 2" shackle. The truck looks perfect and rides like stock but it's not the cheapest route...
