The new Pro X Series Tower Extension is the most extreme new product to hit the market. It fits all tubular towers and allows riders to go bigger and land softer. It also helps you learn new tricks at slower speeds which will increase your confidence while reducing the punishment of crashing. Trying to land that first raley? Slow the boat to 18 mph and give it a rip. It also folds down entirely and can remain attached while your tower is collapsed, so there is no need to remove it prior to parking your boat on the lift. Fits all tubular towers on the market.
