Get all the performance of our latest technology in a package that is more accessible and simpler to use

The Stage 4 model is derived directly from our top-end Stage 5 model, with which it shares most of the same components. It features a single external compression adjustment knob that controls the low-speed compression damping that is combined with an internal high-speed blow-off circuit which relieves peak pressure upon impacts to achieve race-level performance in a package that is more accessible and easier to adjust.


  • Helps increase and maintain speed over rough terrain and bumps
  • Reduce ski lift and front-end pushing, making the sled easier to steer in corners
  • Prevents bottoming-out upon harsh square-edged impacts and obstacles
  • Provides increased hookup in all conditions for maximum maneuvrability
  • Allows good control of key parameters without too much complexity


  • Front ski shocks, 36mm, coilover, sold as a pair
  • Center track shock, 36mm, coilover or non-coilover, sold as a unit
  • Rear track shock, 36mm or 46mm, coilover or non-coilover, sold as a unit
  • Configuration varies according to vehicle model and year



Allows fine-tuning of the damping resistance when the shock is being compressed slowly. This adjustment controls weight transfers such as upon acceleration and braking, ski lift and front-end pushing when cornering, riding over whoops at moderate speed, undulations and elevation changes in the terrain.

To use, turn the red knob clockwise to increase damping resistance, therefore making the suspension stiffer or turn counter-clockwise to reduce damping resistance, therefore making the suspension softer.


Controls the speed at which the shock absorber returns to its fully extended position after being compressed from an impact, keeping the skis or track on the snow for maximum traction and reducing the bucking effect caused by the spring pressure pushing back after an impact.

To use, turn the adjuster clockwise to slow down the rebound or turn counter-clockwise to speed up the rebound.


Available on all front ski shocks and coilover models at the center or rear position. Lets the rider fine-tune the initial force applied on the springs and precisely balance the weight distribution across the front and rear of the sled while setting up the ride height (sag) and to lower or raise the sled to adapt to various situations or to suit your personal preference.

To use, turn the preload adjustment ring clockwise (from top of the shock) to increase preload and raise the vehicle or turn counter-clockwise to reduce preload and lower the vehicle.
