The first line of ballast bags offered in 5" increments and designed specifically for use in the rear lockers of v-drive boats.


When our engineering team sits down to design a new product, the first question we ask is “why is this product important?”. In the case of our industry changing UniversalFIT Rear Locker Ballast bags, the answer to that question was both simple and transformative at the same time; we weren’t happy with the existing one-size fits all approach every other brand had taken. The products that were available weren’t ones that we would use in our own boats, and we knew we could offer better fit, more capacity, and better quality in a wakeboard ballast bag that was purpose built for the application in the United States, and offered in a wide array of sizes.

The result is the WakeMAKERS UniversalFIT Rear Locker Series line of ballast bags. These bags are offered in numerous sizes to give you a nearly perfect fit without the expense of a custom bag. In addition to that, when our team started to look at the rear lockers on most boats, we found common trends of the compartment being wider at the top than the bottom, and a slight taper on the front formed by the rear seat back. We designed the UnversalFIT Rear Locker Bags to match the overall shape for the best possible fit.

Add in our industry leading quality that starts with incredibly high strength material that is optimized for both tear and puncture strength, 1” full overlap seam construction, and our unique 1” DryLOK ports, and you have the most innovative wakeboard ballast bags available combined with quality that ensures they will stand up to years and years of use.

If you are shopping for ballast bags to put in your v-drive boat, there simply is no alternative to the design, fit and quality of the UniversalFIT Rear Locker bags. Additionally, we offer them with our exclusive factory ballast upgrade solutions which makes it incredibly easy to add capacity to the ballast system in your boat for a better wake or wave.

You can also use our UniversalFIT Rear Locker ballast bags with a portable ballast pump or integrate them with a WakeMAKERS fully automated ballast system.

As with all WakeMAKERS products, we strive to build the best products offered anywhere, the products we would want our friends and family to be using. Our team is thrilled with the UniversalFIT Rear Locker Series ballast bags, how well they perform, and the fact that they redefined a class of product that had been stagnant for over a decade. We’re confident you’ll agree, and love these ballast bags.


There are NO FITTINGS OR PLUGS included with these ballast bags

In order to allow you to customize the these bags to your application, we do not include any fittings. Please make sure to order a total of five fittings and/or plugs for each bag. If you have questions about the correct fittings for your application, please feel free to contact us.

    Great for lockers in 2005 Wakesetter VLX
    Timothy Williams

    I put a pair of the 910 lb bags in the rear lockers of my 2005 Malibu Wakesetter VLX (along with a bow sac) and have been very happy with the improved size of my wake. I can finally surf behind it. The bags are thick and tough with plenty of ports. They fit the lockers well. Only downside is that no plugs are included; which at least was made very clear up front. Would have been nice to include then considering the price but the sacs are great overall!

    Awesome! Gave my wake a huge boost and super easy to install
    Nelson Ocampo

    I have a 2014 Mastercraft X2. With factory ballast wake wasn't able to keep me there without the rope. I'm 6'3 and 210lbs rocking a Hyperlite Quad surfer. Spent 10 minutes installing both rear bags (super easy, no tools needed if boat is plug-and-play ready). Boy what a difference!! Can now play on the wake throughout different lengths without the rope. Easy to fill and empty and took only a couple of trials to get the pump timers right to where we wanted them.

    Love these bags!
    Paul Edwards

    These bags are very well constructed. You need 4 vent plugs and a Wakemakers Tsunami plug if you plan on using a Tsunami pump over the side. Love that you can choose between multiple sizes. Made a huge difference sitting in my locker on top of my Centurion Ramfill tanks in my SV233. I had a very good wave before. It is phenomenal now.
