Supra 20SSV Rear Ballast Upgrade (2006-2009)

Unlock your 2006–2009 Supra 20SSV's full wake potential with the WakeMAKERS Factory Ballast Upgrade Kit, designed to replace the stock rear ballast bags with high-capacity FIT Series bags that deliver bigger, cleaner wakes for wakesurfing and wakeboarding.

This model-specific upgrade is engineered to fit perfectly in the rear lockers of your Supra 20SSV, maximizing space and boosting total ballast volume. The result? A dramatically enhanced wake without compromising the factory integration or requiring complicated installs.

Whether you're looking to generate more push for surfing or a steeper face for wakeboarding, this ballast upgrade is the perfect way to improve your boat's performance without adding extra switches or pumps.

Why Upgrade?

The factory ballast bags in the 2006–2009 Supra 20SSV were not designed to fill every inch of available space, leaving performance on the table. This WakeMAKERS-exclusive kit replaces those smaller stock bags with 640lb UniversalFIT bags on each side, making the most of your rear locker space and significantly increasing wake size and quality.

OEM Integration, No Hassle

Your upgraded ballast bags will work seamlessly with the boat’s existing ballast system. Simply control everything from your dash using the original ballast switches. This is a true plug-and-play upgrade—no drilling, no wiring, and no extra equipment needed.

Easy DIY or Pro Install

With all pre-assembled fittings and connectors included, installation is straightforward and can be completed in just a few hours in your garage. Prefer professional help? Any WakeMAKERS-certified installer can have you surf-ready in no time.
