Technical Features:

These monotube shocks only use a single outer tube. The oil and gas are separated by a free floating piston which puts the oil on the top and Nitrogen gas on the bottom shock body in high resistance alloy steel with a CNC machined billet aluminum head.

The monotube shock design contains a larger active piston surface area, which means greater and more consistent damping force.

  • Lower operating pressure leads to more consistent and controlled rides.
  • Other benefits include increased oil capacity, improved heat dissipation, and longevity.
  • The free-floating piston valve never allows oil and gas to mix thus minimizes foaming. The overall effect is that monotubes offer better and more precise damping.
  • Monotubes are more durable; require minimal maintenance and the cost in the long run is much lower.
