S5 Sentinel Suspension Base

The Shockwave S5 Sentinel provides comfort and safety to boaters, offering them an experience they’ve never had before. It offers a smoother, safer and more comfortable ride, protecting occupants from the shock of wave impact. Recreational boaters can stay out longer and travel farther with less fatigue. The S5 Sentinel comes in a matte black or glossy white finish. It is easily and quickly installed in virtually any boat and can be mounted on a riser box or a short, stocky pedestal with minimal effort.

Suspension travel is 4-inch vertical and 1.5-inch forward, mitigating deceleration associated with wave impacts.

Please note that you will need a SHOCKWAVE Shock Pump in order to operate your S5 Sentinel Suspension Module. A shock pump will automatically be added to your cart.
