The best fitting ballast bags for the rear lockers of v-drive boats. The WakeBallast UniversalFIT rear locker bags are offered in nearly 20 incremental sizes, delivering a nearly custom fit and improved wake.

Our LIMITED WakeBallast UniversalFIT Rear Locker Ballast Bags are making a splash in the industry and forever changing how boaters look at ballast bags. The team of product designers and engineers at WakeBallast agreed that a 'one-size fits all' approach that other brands are taking isn't good enough. Seeking a better ballast solution than standard sized bags, we developed our series of UniversalFIT ballast bags, designed for specific zones of your boat and offered in incremental sizes to give you better fitment and improved wake performance.

Ranging from 400 to 1,200 lbs. in size, the UniversalFIT Rear Locker bags allow you to choose the dimensions of the bag in 5" increments. The result is a much better fitting bag for your boat's rear locker, allowing you to fill to capacity and maximize added weight for the best possible wake. WakeBallast UniversalFIT ballast bags give you a nearly perfect fit without the expense of building a custom bag.

All WakeBallast ballast bags come standard with an industry-leading two year warranty. The bags are constructed of a DuraTEK, our proprietary material that is strong, durable, and puncture resistant. Once the material is cut, the bags are RF welded together with 1" seams to ensure a clean look and watertight seal. There are five 1" NPT ports on this ballast bag that feature a tapered thread pattern and bottom o-ring for a leak-free seal. The larger port size allows water to flow quicker for faster fill/drain times.

If you are shopping for ballast bags to put in the rear lockers of your v-drive boat, the WakeBallast UniversalFIT ballast bags are a no-brainer decision. From the quality craftsmanship to the innovative design, these ballast bags are built to deliver improved wakes behind your boat.

Sold individually as seen here, these bags are also included our WakeBallast LIMITED Factory Ballast Enhancers that integrate the bags into your boat's factory ballast system for automated filling/draining. Use the dropdown tool to find available factory ballast Enhancers for your year, make, and model boat.

You can also use our UniversalFIT Rear Locker ballast bags with a portable ballast pump or integrate them with a WakeBallast Complete Ballast System for automated filling/draining of the bags.
