Race sponsons. A great two seater fun boat from Sea-Doo but lacks directional stability at speed in choppy water conditions and has a bad tendency to over steer. If you start to turn sharply the OEM sponsons bite and spin the boat into a hard turn that you can’t pull out of. The worx sponsons change that and make this boat a pleasure to ride as you can run as fast as you like with complete control and turn as hard as you want to again in control. WORX RACE SPONSONS High performance sponsons are manufactured to specific designs to suit each boat from H.D.P.E. (High Density Poly Ethylene) a very tough solar resistant material. All sponsons are supplied with full detailed set of instructions and all necessary stainless steel hardware to install the set of WORX Sponsons. Fits all RX, sll RXX and all RX DI.
