RIVA Racing Pro-Series Sponsons — Sea-Doo RXT/GTX 2018+ & RXP-X 2021+

Take command of the water with RIVA Racing's Pro-Series Sponsons — the same race-proven technology trusted by competitive riders to unlock the full handling potential of their Sea-Doo. Whether you're carving aggressive turns, running straight-line speed, or simply want more confidence on the water, these sponsons deliver a transformation you'll feel immediately.

Why Riders Choose the Pro-Series

Stock sponsons are a compromise. RIVA's Pro-Series are not. Engineered with a cutting-edge stepped surface design and high-strength fin material that refuses to flex under pressure, these sponsons dramatically improve both cornering grip and straight-line stability — giving you a planted, predictable ride no matter the conditions.

The bulletproof billet aluminum mounting inserts eliminate the weak points found in lesser designs, ensuring your sponsons stay exactly where you put them, lap after lap, season after season.

Dialed In, Your Way

Every rider is different. That's why RIVA built in a fully adjustable five-position fin system, letting you fine-tune exactly how much influence the sponsons have on your craft's handling. Run them aggressive for the track, or back them off for a more comfortable cruising setup — the choice is yours.

Bolt-On Simple

No drilling. No fabrication. No guesswork. The Pro-Series Sponsons install using your craft's original mounting points with all hardware and instructions included. If you can use a wrench, you can install these in your driveway.
