Expand the capacity of the factory ballast system in 2012 and newer Malibu wakeboard boats without the factory plug and play option for the perfect wakeboard and wakesurf wake.

Please check the size of the hoses in your boat before ordering; early 2012 production boats still used 3/4" hose, and will require our 2005-2011 Malibu PiggyBack Rear Factory Upgrade. If you have any questions about determining the correct application for your boat, please contact us.

Our exclusive Malibu PiggyBack ballast upgrade solution has been completely re-engineered for far faster draining, and even easier installation.

Interested in adding more ballast to your NEW 2012 Malibu boat for surfing, but don't want to hassle with filling ballast bags by throwing a pump over the side of the boat? Our exclusive Piggyback ballast upgrade allows you to add an additional 400-1,100 pounds of fully automated ballast to the factory MLS system on your Malibu wakeboard boat.

WakeMAKERS PiggyBack Packages are designed to integrate with your factory ballast system, and are controlled using the switches on your dash, so everything remains completely automated and effortless to use.

How It Works
The Malibu PiggyBack Ballast System is designed to make use of the existing pumps, hoses and switches in your Malibu boat, to expand the capacity of your factory rear ballast tanks from 250lbs. up to an incredible 1,350lbs. This kit includes everything you need for the installation, including a replacement ballast big (choose your capacity), quick connect fittings, all necessary fittings and adapters, hose and installation guide.

As the name implies, this ballast system add-on is connected inline with the overflow of the factory ballast tank, allowing it to PiggyBack on the factory system. In the factory configuration when the in-floor hard tank is full excess water is dumped overboard through the vent hose. With the PiggyBack system installed, excess water from the hard tank flows into the ballast bag, allowing it to fill after the factory tank is full. Once the new bag is full (which means the factory tank is full), excess water will flow out of

    Pretty Legit
    John Andrus

    I had my dealer install these bags on my 2012 MXZ on top of the hard tanks. I went with the 600 sacs. My surf wave got a lot better and my wake is huge now. They drain and fill with ease. My only problem with them is that they cause the rear coolers to pop out when full and sometimes cause the engine compartment panels to pop out of place. Still worth the upgrade though.

    Worth Every Dollar

    Even though it was a bit of a pain to install - WM helped me through it. The new double bottom port bags drain so much faster - it's an essential upgrade. There are so many ways to customize your ballast now with WakeMakers!
    My VLX surfing experience is a lot better with the ability to drain & fill so fast with the piggy back setup.

    Great Service

    You will not beat the service from I had an early model 2012 with the 3/4" hoses and they took the 2012 kit back and sent out the proper kit. Walked me through all the steps for install. Thanks again!
