Shockwave S5 Sentinel Marine Suspension Module — Pump Included

Experience unmatched on-water comfort with the Shockwave S5 Sentinel, a premium marine suspension module engineered to deliver a smoother, safer ride in all conditions. Designed and manufactured in Canada, the S5 absorbs wave impact to protect your body from the harsh vertical forces that cause fatigue and long-term back strain. Whether you’re cruising, fishing, or running long distances, the S5 helps you stay out longer with less effort and greater comfort.

The S5 Sentinel installs quickly on virtually any boat and pairs easily with most seating systems. Built from marine-grade aluminum die-cast components with a trivalent chromate finish and military-grade powder coat, it offers exceptional strength and durability. The fully adjustable shock absorber — FOX FLOAT or RockShox, depending on configuration — allows you to fine-tune compression and rebound to match changing sea conditions and payloads. Its 8-pivot design provides increased lateral stability and a noticeably smoother ride, while IGUS bushings and 316 stainless steel hardware ensure long service life in harsh marine environments.

With 4 inches of vertical suspension travel and 1.5 inches of forward surge protection, the S5 significantly reduces deceleration forces associated with wave impact. This results in better control, less body stress, and a dramatically improved ride quality.

Harbour Chandler now offers the S5 Sentinel complete with the required Shockwave pump, making setup and adjustment simple right out of the box.
