Kawasaki 440 / 550 Ride Plate

(5 customer reviews)


Kawasaki 440 / 550 ride plate reduces nose bouncing (porpoising) and improve rear grip. We recommend installing with our proven silicone adhesive.


The ProWatercraft Hybrid Flex Composite (HFC) ride plate for the Kawasaki 440 and 550 is designed to flex supporting your riding style. HFC blows all the other rigid plates out of the water with many improved features over the standard rigid plates. This plate not only holds up better than the industry standard aluminum and fiberglass ride plates, but limits bouncing, reduces subbing, even MORE stability, and better grip.

This ride plate is designed to greatly improve rider confidence. This will make your ski feel like it’s a train on rails.  The difference between us and the other options on the market is grip and high speed turning the ski is easier to lean which makes the ride smoother through the complete turn. Race proven, designed by the pros, run by recreational riders and racers around the world!

Product fits: Kawasaki 440 / 550 (SX / JS)
Installation time: 10 minutes or less


  • How do I install this correctly?
    Due to the natural flex of our ride plates we require you use this plate with silicone around the bolt holes and Loctite on every bolt. This is also the industry standard on how all ride plates should be installed. Tighten only until the bolts a snug. Check after your first ride and routinely throughout a season.
  • How much longer is this plate compared to stock?
    This skid plate is about 1 inch longer than the stock ride plate. We chose an inch because our fins and angle of plate were enough to drive the nose down more for the stock setup, reducing porpoising.
  • Will this fit with the Rhaas 550/750 conversion kit?
    No, the pump shoe conversion is much larger than stock which doesn’t allow for stock-shaped ride plates. You may modify this plate but this will void the warranty.
  • Is this part legal to race with?
    You will need to check the rules from your racing organization to verify if this part is legal for competition. ProWatercraft takes no responsibility if you are disqualified from this part breaking any racing organization rules.

    This ride plate definitely hooks the rear of the ski up in the corners, helps keep it from porpoising on the straights and makes it feel way more stable at speed.. quick instal and perfect fit..

  2. Bill Kinnison (verified owner)

    Improved the porpoising & made the ski carve better in the turns. Loving it on my 550SX.

  3. Matt Miller (verified owner)

    Added ride plate to my JS550 and what day and night difference. Makes ski so stable especially at higher speeds. Couldn’t be happier and would recommend this ride plate over others I’ve tried.

    If you’re looking for a ride plate that’s gonna hook up in the corners, look no further! I put this on my 550SX and paired it with the ProWatercraft steering nozzle, what a difference!! Don’t wait, try their products now you won’t regret it!

    I’ve added this plate after doing front and rear sponsons on the 550, and the biggest change is aggression and grip. The rear and never comes unhooked now, and it will grab hard enough to throw you every turn. This pushed my corner speeds up on the 550 to where I never thought I’d be. All 3 mods together make the 550 a very modern handling machine.
