For those who currently ride or wish to ride a longboard, our product is designed to provide a variable fortification to your board based on your desired level of riding for the day.

Made of Top quality Aircraft Grade Billet Aluminum, the “PhatBlox Sk8spension Pro-Series Black” allows for a rider of any longboard to adjust the flexibility of his/her longboard.


  • Board Fortify – Strengthens the board for control, agility and weight capacity
  • Flex Fortify – Adjustable flexibility for your desired ride experience
  • 3D Fortify – A 3rd option of adjustability, to fine tune your boards suspension
  • Brand Fortify - Installs in minutes on many popular brands of longboards


Imagine if you were planning a day of simply carving up the boardwalk at the beach, where your board is simply cruising along, nice smooth turns and excellent flexibility offering you a satin smooth look and feel as you carve your way through the crowd.

Now imagine taking the same board and feeling the need for speed, and in this case you really want to remove the flexibility of the board to provide a more solid ride while carving up a mountain road with strong stable cornering and a strong solid feel under your feet.

The 42fi “PhatBlox Sk8spension Pro-Series” kit creates that difference for you

One fine unique difference to our product is that it will install easily onto any top brand boards, thus allowing you to use any top designer board and add a fortification to the board that provide a larger range of boarding experienced that the designer originally intended.

As an example; you see a really cool Sector-9 48” longboard, go ahead this board is a great board, but when you add the 42fi systems “PhatBlox Sk8spension Pro-Series Black” to it – it becomes amazing.
