Supra Sunsport 24V Rear Ballast Upgrade (2005-2010)

Take your 2005–2010 Supra Sunsport 24V to the next level with this WakeMAKERS Factory Ballast Upgrade Kit. Built specifically for the large rear lockers on the 24V, this kit replaces your factory ballast bags with custom-fit 1,280lb WakeMAKERS FIT Series bags, giving you maximum ballast capacity and the wake performance to match.

Perfect for both wakeboarding and wakesurfing, this upgrade helps your boat displace more water, creating a taller, longer, and more powerful wake—all while maintaining full integration with your existing dash-controlled Gravity III ballast system.

Unlock Hidden Potential

The stock ballast system in the Sunsport 24V leaves much of the rear locker space unused. Our 1,280lb UniversalFIT bags are specifically selected to fill that space efficiently, increasing the total ballast and making a noticeable difference in your wake's size, shape, and push.

Factory Integration Made Simple

Designed to work seamlessly with your boat’s Gravity III ballast system, this upgrade requires no extra wiring, switches, or plumbing. Just remove the factory bags, drop in the upgraded FIT Series bags, and install with the included pre-assembled fittings and connectors. You'll retain full ballast control through your original dash switches.

Easy DIY or Pro Install

Everything you need is included, and the kit is designed for a straightforward DIY install—no custom fabrication or wiring needed. Most installs take just a few hours. Or, have a WakeMAKERS-certified shop install it for you.
