What's included

  • Crossmember box — structural reinforcement for the frame mounting points.
  • Skid plate box — protective underbody coverage for off-road duty.
  • 4.5-inch box strut kit — secondary lift and dampening control.
  • M1 monotube shock pair — premium damping elements for ride quality and stability.
