WakeBallast 2013 Supra Launch 21V Custom Rear Ballast Larger Bags
More weight in the rear means a bigger wake and a better surf wave. This bag drops directly into your factory ballast system — no custom plumbing, no rewiring. It fills and drains automatically using your existing dash switches, just like stock, but with significantly more capacity.
Built in Chandler, Arizona and backed by a 2-year warranty. Most orders ship within 48–72 hours.
Each bag comes with male quick release 1 1/8” fittings to connect to your existing female quick release hose ends. If your boat requires different fittings, browse our fittings here.
These Ballast Larger Bags - BAGS ONLY - replace the stock ballast bags in your Supra with our FIT Series bags that fit better and maximize the space of the rear lockers, increasing the ballast system's overall capacity and producing a bigger wake.
Our aftermarket ballast solutions increase the overall capacity of your Supra boat's factory ballast system for improved performance while keeping the convenience of controlling all ballast with the switches at your dash and integrate directly into your boat's existing automated filling/draining.
There is plenty of space in the rear lockers to hold a larger capacity ballast bag. The FIT ballast bag is specially selected for your boat, ensuring a proper fit and maximized capacity. The install is quick and simple, practically a plug-and-play solution for building a better wake.
It is designed to be a user-friendly DIY install that can be completed in the course of an afternoon or by a professional if you prefer help
