Superjet Wedge Rear Sponsons

(1 customer review)



Our Performance Wedge Rear Sponson kit is designed to improve the riders confidence when riding their Stand up watercraft. These sponsons are great for faster riders looking to get more performance and top speed out of their watercraft while still maintaining stability and rear grip. The “wedge” on the back of the sponson allows some lift in the rear ski to reduce drag and can see performance gains of anywhere from 1-2mph – all while still maintaining the straightline stability and corner grip that you want for fast riding.

What You Need to Know:

  • For the lifetime warranty, you need to install this product with ourĀ approved silicone. Apply silicone to all the edges and wipe off any excess from the surface of the product after installation. Smooth out any excess silicone along the edges as well. Allow the silicone 24 hours to cure.

  • This product fits: SuperJet 2007+
  • Installation time: 30 – 45 minutes

  • What is the difference between these and the regular rear sponsons?
    The wedge design ramps the water away from the back lip of the bond flange which increases speed. Also, both have the serrated edge that has proven to reduce lift and improve rear grip.

    I think they’re great. My wife has a 13 SJ without and I have a 16 with. We’re both running the Prowatercraft ride plate. We both agree that mine grips noticeably better for rec riding and is much less likely to slide in corners. Very good bang for the buck.
