Included Shocks

Our Multiple Shock system for GM HD’s features an upper hoop constructed of 1.5” OD x .120 wall DOM tubing that attaches to the frame with the lower mount fastening to the stock lower control arm. This design places the shock load on the frame and large lower control arm as the factory intended it for increased strength and ball joint longevity. System allows use of Performance Shocks or Dirt Logic 2.0 Resi Shocks that have been extensively tuned for a quality ride both on and offroad.
