WakeMAKERS Supreme S238 2016-2021 BagBuster Rear Factory Ballast Upgrade



This WakeMAKERS LIMITED Factory Ballast Upgrade replaces the stock bags in your Supreme with our bigger ExactFit Series ballast bags for the maximum ballast capacity possible.

WakeMAKERS LIMITED Factory Ballast Upgrade Kits are built and designed to unleash your boat’s full potential. It takes more than just the stock factory ballast to properly weight the boat for an optimal wake. Through the installation of this Upgrade kit, get ready for a more enjoyable wakesurfing and wakeboarding experience behind your Supreme boat.

Our aftermarket ballast solutions increase the overall capacity of your Supreme’s factory ballast system for improved performance while keeping the convenience of controlling all ballast with the switches at your dash. The WakeMAKERS ExactFIT Series ballast bags included in this Factory Ballast Upgrade will be integrated directly into your boat’s existing ballast system for automated filling/draining.

This WakeMAKERS Factory Ballast Upgrade adds additional capacity to your boat’s factory ballast system by replacing the stock ballast bag with higher capacity ballast bags. The ballast bags that came stock with the boat are not large enough to hold the necessary weight for building a sizeable wake. Additionally, there is plenty of space in the rear lockers to hold a larger capacity ballast bag. The Upgrade kit includes WakeMAKERS ExactFIT Series ballast bags that are specially designed for your Supreme, ensuring a proper fit and optimal capacity.

The Supreme S238 is a fantastic platform, but to get the best performance for surfing, it needs more than the factory ballast system offers. Our solution adds over 1,600 lbs. and will get you the results you want. The ballast bags in the rear lockers are symmetrical and will fill the entire space as they are built based off of 3D scans of the locker spaces. As custom made bags for this boat, the bags connect directly to the factory fill/drain and vent lines for a quick, easy install. The rear locker bags each weigh 610 lbs. Two additional bags are placed under the midship seats and are connected to the front panel of the rear locker bags through our LIMITED bridge connect system. This system allows both bags on each side to function as one location for automated filling and draining.

Unleash your Supreme’s full potential and get ready for more fun on the water. Every WakeMAKERS Factory Ballast Upgrade is designed to be a user-friendly DIY install that can be completed in your garage over the course of an afternoon. Don’t want to do a self-install and would rather take your boat to a professional? These Enhancers can be completed by your local WakeBallast certified boat service center.

What’s Included: Each WakeMAKERS Factory Ballast Upgrade includes the best fitting ballast bag(s) for your year, make, and model boat along with all the needed ballast hose and hardware to integrate into your boat’s factory ballast system.
