The Zone Offroad 5" lift kit for your Dodge Ram 2500 includes coil springs, heavy duty greasable control arms, bump stops, pitman arm, track bar relocation brackets and 4 Zone shocks. Shock boots sold separately. The factory block is replaced with a 5" block and add-a-leaf for a level stance. Because the factory drag link mount taper will be flipped when the pitman arm is installed, a steering stabilizer is required and ordered separately.
Your Ram 2500 could have front factory sway bar links mounted either above or below the axle bracket. Only if your model has the factory front sway bar links mounted ABOVE the axle bracket, do you need to order the optional sway bar link kit D5501. If you're not sure, look at figures 10 and 11 in the instructions.
