What's included

  • N3 shock absorbers (qty 2 pair) — valved to complement the lift and deliver balanced on-road and off-road performance.
  • Brake line relocation brackets — reposition factory brake lines to clear the lifted suspension components.
  • U-bolts and hardware — grade-8 fasteners and spring clamps for secure, durable assembly.
  • Spring bushings and installation kit — includes all brackets, hardware, and detailed instructions.
