Shockwave S5-SS Stainless Steel Suspension Seat Base

The Shockwave S5 Suspension Bases revolutionize the boating experience by delivering unparalleled comfort and safety. This advanced suspension system ensures a smoother, safer ride by cushioning the impact of waves and reducing fatigue, allowing boaters to stay out longer and explore further.

Built with welded, electropolished 316 stainless steel for lifelong durability, the Shockwave S5-SS is ideal for saltwater environments with high salinity, humidity, and moderate to heavy sea conditions.

With 4 inches of vertical suspension travel and 1.5 inches of forward travel, the S5 Sentinel minimizes the deceleration from wave impacts, enhancing stability and comfort.

It's designed for easy and quick installation on virtually any boat, mounting effortlessly on a riser box or short pedestal.

Experience unmatched support with the S5-SS Suspension Base - engineered to handle up to 136 kg (300 lbs) with ease, so you can enjoy comfort and confidence every time you sit.

Each seat base is supplied with the necessary Shock Pump & Gauge to operate the S5 suspension base.

Shock Compression Adjustment Settings:

Setting the sag height is designed to be a starting point. To get the most out of the suspension base the shock absorber can be fine-tuned. This is done using a combination of compression and rebound tuning to optimize ride quality as well as for varying sea conditions.

The suspension base comes with a 2 or 3 position blue lever that is designed to make quick adjustments to optimize the performance of the shock absorber in varying sea conditions. You can select three settings:

Soft mode: For operating in flat water and light chop where the likelihood of experiencing a slam is low. Mostly inshore use. Gives a soft ride.
Medium mode: For operating in moderate to rough conditions where some slamming could occur. Gives a medium ride.
Firm mode: For operating in big seas and at higher speeds where regular slamming will occur. Gives a firm ride.

Rebound Adjustment

Rebound controls the rate of speed at which the shock returns to the sag position after compressing. The rebound adjustment is dependent on the air pressure setting. Higher pressure requires slower rebound settings. Use the procedure below to find the correct rebound setting.

Faster Rebound: In high frequency and small wave activity, a faster rebound can improve your suspension performance. Turning the red rebound adjuster counter-clockwise will make the seat rebound faster.

Slower Rebound: In low frequency and large wave activity, a slower rebound can improve your suspension performance. Turning the red rebound adjuster clockwise will make the seat rebound slower.
