2022 Slingshot PFI 633/710 Lower Foil Set Specifications


The Phantasm Freeride Infinity (PFI) 633/710 Lower Package features a larger, lower aspect front wing that gives it tons of lift, stability and dynamic performance at lower speeds, a well as a PS 400 carbon rear stabilizer and 710 fuse. The PFI 633 package was built to provide you with maximum freeride performance as the most predictable and user-friendly foil on the market.

At higher speeds, the PFI 633 will track and retain its stability, which aids in setting up for jibes and tacks and also prevents over-foiling. The larger surface area of the PFI 633 Front Wing, combined with the efficiency of carbon means it has a huge wind and speed range. The wing’s unique inverted gull shape provides a crazy level of dynamic carving control and a self-centering flight you have to feel to believe.


  • Provides the best all-around performance on the market
  • The perfect blend of speed stability, lift and maneuverability
  • Progress quicker and easier than ever before with smooth, unmatched stability
