Shockwave S5 Sentinel Lightweight (S5-LW) Marine Suspension Base — Pump Included

Experience smoother, safer days on the water with the Shockwave S5 Sentinel Lightweight — now packaged with a shock pump included, making setup and fine-tuning easier than ever. This universal marine suspension base is engineered to absorb harsh wave impact and reduce the cumulative strain that leads to fatigue and long-term back pain, helping you stay out longer and ride more comfortably.

Built from anodized 360 cast aluminum, the S5-LW features a custom-tuned X-Fusion O2 R air spring and shock with adjustable rebound. Its lightweight, compact design delivers exceptional suspension performance without extra bulk, and every unit is finished with a durable black or white powder coat and stainless steel hardware for long-lasting durability in marine environments.

Compatible with nearly any seat and nearly any boat, the S5-LW installs quickly and is commonly used on fishing boats, coastal cruisers, guide boats, ski/wake boats, whale-watching vessels, crew boats, and yacht tenders. By reducing both high-impact hits and repetitive wave shock, it helps protect your body from the punishment of rough conditions so you can fish, play, and guide longer.

Harbour Chandler is proud to offer the S5 Sentinel Lightweight complete with the required pump, giving you everything you need to dial in your suspension right out of the box.
