The PiggyBack Factory Ballast Upgrade improves the total capacity in each rear locker to over 1,000 lbs. by integrating custom fitted WakeMAKERS Rear LBS bags above the existing 250 lb. factory hard tanks.


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

Unlock your boat's performance by adding over four times the capacity to the factory ballast system.

The factory rear hard tank in your boat currently holds 250 pounds of water. Our PiggyBack upgrade will allow you to add an additional ballast bag on top of the factory system for over 1,000 pounds of wake building capacity in each rear locker! Just imagine the improvement in the surf wake you'll see with that much additional weight.

LBS Ballast Bag Features

WakeMAKERS LBS Ballast Bags

The WakeMAKERS Locker Ballast Solution (LBS) ballast bags give you the fit of a custom bag without the lofty price tag. Designed to mimic the actual shape of the rear lockers in a v-drive boat, the bags feature a sloped front panel and gradually get wider at the top. The result is a truer fit that results in more capacity (a bigger wake!)

Available in a multitude of sizes, you can be sure that the LBS bag selected for your ballast upgrade will fit and perform much better than a standard off-the-shelf ballast bag.

    Good but has some frustrating quirks
    Nolan Miller

    First I'm going to say I have gotten two of these and isntalling them was not as easy as they say. I averaged about one and a half hours installing one. Also if you are planning to fill them fully you will need the divider supports. Figured that out the hard way as we were filling it we blew a divider panel as it was filling. The thing that makes me the most angry about these so far is that the fittings for the bag cross thread very easily. I do not know exactly why they do this but now I have cross threaded it three times now! Other then that they fill and work great.
