Performance Front Sponsons for any standup watercraft.


Our HFC Front Sponsons bring functionality with cost effectiveness. These Performance Sponsons offer improved turning grip, better stability in a straight line and very important improved stability when leaning over in a turn. These HFC sponsons are tough and durable and comes with a flat black finish to grip the water better than the competition. The kit includes 8 stainless steel screws for each side and a tube of silicone to attach it to the outside. This process has proven to be the easiest and most effective way to install front sponsons. Race proven, designed by the pros, built to evolve your style.

We recommend these for anyone looking to shred better. Front sponsons increase the overall stability of your ski while making it easier to

Because these sponsons are made out of our HFC material they are a universal fit, and the same sponsons fit and flex to any hull.

  • How do these sponsons compare to the Fattie front sponsons?
    The Fattie front sponsons were designed to be a bit wider for straight line stability and more rider friendly, making turning smoother. The Performance front sponsons were designed for a more aggressive turning for buoy riding and racing. Both options will make your ski more stable.
  • What’s the difference between the HFC and fiberglass sponsons?
    Our HFC front sponsons are more cost effective and more durable compared to the fiberglass which can delaminate and stress crack.
  • Do the PWR sponsons make the difference?
    Yes, these are not another copy of someone’s design. This product was made by the Pros that demanded more stability and grip. We have seen this same design helps all rider levels to evolve their style and performance.
  • Are these sponsons race legal?
    Yes. Please check your racing association’s rules for your application.
  • Are these front sponsons paintable?
    Yes. We recommend keeping the surface a matte / flat finish to keep the handling of the sponsons predictable. A lot of the performance comes from the standard flat finish on our sponsons.
  • Do you offer options for side exhausts?
    Yes, but only for the Kawasaki 550 at this time, see the install pictures above. Other standup ski models and exhaust outlets will require modification to the sponson (voids the warranty) or relocation of the exhaust port.

    I am very pleased with this part. Those guys did a great Job, as usual with shipping Internationally. I have 2 skis (SXR) with 2 diferent Sponsons (Blowsion and Prowatercraft). Both are good , but habdle different . I like the ProWatercraft better because you have much more control when curving…a good way of describing it “You find it instead of it finds you”….
    My SXR is much more easier on turning and even strach line then a stock boat for sure! It defenitely worth the money!

  2. Deegan Newton (verified owner)

    I put these sponsons on my Sxi Pro, and made it feel like a completely different ski…
    They made the ski feel way more stable at high speeds,. I am also able to hit the turns at high speed without the ski slipping out, and the sponsons reduced the front from wanting to dive into the water.
    Awesome product!!!

    I ordered two sets for my sn and 650sx. Worked out great on both. Install was easy and the directions/YouTube video were great. I would highly recommend.

  4. Brian

    Wow! Wow! Wow! I have a Kawasaki 96 sxi with quite a few mods. These are hands down the best mod you can put on a kawi 750. I was thinking of selling my ski to get an 800sxr…. NOT ANY MORE! Handles like a carving machine and much more stable. Great product. Install took about 1 he and easy.

  5. Adam Leech

    These are a must have on any 440/550! Night and day difference! If you can only put one part on your ski this has got to be it!

  6. Kevin Knopf

    Just put these on my 550SX and could definitely tell a difference! Awesome products as always from ProWatercraft!

    I have two 550’s. I tried these out on one. It is so much more fun to ride with these sponsons. The ski dose not porpus as much and it has a very controllable roll as you turn. Plus it keeps the front end from diving under in a corner. Hands down the best mod for a 550. I am going to bye another set for my second ski. Just wish they were white. But who cares when they make it so much fun..
