The Fly High Pro X Series Rear Gravity Games Sac is built to fit in the rear compartment of Supra and Moomba v-drive boats from the early 2000’s and has a related capacity that is 165lbs. more than the stock 400lb ballast bag. Two of these sacs combined with the Gravity Games Center Sac provides over 2,300lbs. of additional ballast in your boat.

It’s easy to see why this is the combination used in all the Gravity Games wakeboard event boats. The Fly High Rear Gravity Games sac will produce a huge, clean wake that will boot you higher. If you don’t have a Supra or Moomba, the Fly High Pro X Series Gravity Games Rear Sac may also be a good option in other boats if the dimensions are what you’re looking for.

Fly High Gravity Games Rear Ballast Bags are a must have upgrade for the perfect wakeboard and wakesurf wake.
