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


Welcome to the future of locker based wakeboard ballast bags.

Our UniversalFIT Rear Locker bags have a unique design that mimics the shape of most lockers on v-drive boats, getting wider at the top, with a sloped front panel. Combined with a multitude of sizes in 5" increments you have nearly perfect fit, in a standard off-the-shelf ballast bag.

NOTE: FITTINGS OR PLUGS ARE NOT INCLUDED WITH THESE BALLAST BAGS. Please make sure to order a total of five fittings and/or plugs for each bag.

WakeMAKERS Rear LBS Bag Sizes

Offered in Multiple Sizes

Rear LBS bags are offered in 5" increment in length, width and height, making it possible to get a nearly custom fit, without the expense of a fully custom made ballast bag.

WakeMAKERS Rear LBS Bag Inverted Geometry

Inverted Geometry

With a unique profile that is 2" wider at the top of the bag than the bottom, these bags are the first to match the rear locker geometry of most v-drive boats, offering maximum capacity and the best fit.

WakeMAKERS Rear LBS ballast bag tapered front panel

Tapered Front Panel

In addition to inverted geometry, Rear LBS ballast bags also feature a tapered front panel that slopes back 2" from bottom to top to match the profile of the rear seat back in most v-drive boats.

WakeMAKERS Rear LBS Ballast Bag Integration Ports

Multiple Integration Ports

We include five 1" Dry-Lok integration ports on every Rear LBS ballast bag for the ultimate in flexibility and future proofing.

    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.

    Ballast upgrade
    Matt Dunn

    Wanted to upgrade the ballast in my 2013 Supra Launch 22v. Ordered the 910LB LBS bag from Wakemakers...The bag fits my locker perfectly when full and made a huge difference to the wave..Bag seems well made and meant to last!!Very happy with how fast my order was shipped!!
    Will definitely be ordering the same bag for the other side!!
