The new Pro Watercraft 440/550 R-Spec Hull Extensions are built for riders looking to push their 550 harder on the water. Designed as a true performance upgrade over the original setup, the R-Spec extensions improve rear hull performance for a more planted, controlled, and aggressive feel at speed.
The updated design helps the ski stay more predictable through rough water, acceleration, and hard cornering while still keeping the lightweight, responsive feel riders love from the Kawasaki 550 platform. Ideal for racers, aggressive riders, engine-swapped skis, and anyone looking for added control and confidence without sacrificing handling.
