1. DJM has the easy solution to drop almost any truck. Ours included the DS2057-3 drop spindles, HS1122-4 hanger and shackle kit, 1315 front Calmax shock absorbers, and the 2200 rear shocks. These components combined offer a 3-inch front, and 4-inch rear drop, and retail for a little over $700. If you’re performing this swap on a C3500, then you’ll want to verify that you have the correct hangers before you start, as the factory hangers offered two sets of rivet locations.
