The patented DuraPro Ski Dampener rubber delivers many unique advantages over any other design: 

  • The unique, one-of-a-kind geometry gives a linear progressive dampening effect which allows the ski to flex more freely at low speeds and loads for softer dampening, and more rigidly at high speeds and loads for stronger dampening. Furthermore, it does this without compromising your ski, bushings, or spindle. 
  • With just the right amount of flex and resistance, the DuraPro ski dampener helps protect your ski, spindle, A-arm, and entire sled by absorbing as much impact energy as possible before allowing the ski to bottom out against the spindle.
  • The dampener maintains the proper ski approach angle position, giving your sled enhanced performance and more predictable handling on the snow.  It's a difference that you will notice immediately, whether on or off trail, and especially when traversing technical terrain and crossing other sled trenches / tracks.
  • The dampener is the width of the ski cradle, offering maximum support for the spindle.  This equates to less wear and tear on your ski bushings, with better twisting and side-to-side stability for the ski.
  • The proprietary composition is extremely resilient and resistant to breaking, cracking, tearing, swelling, abrasion, friction, temperature fluctuations, UV light, and vibration.
  • The majority of the DuraPro Ski Dampener’s effect occurs behind the spindle tab. This puts less stress on the tab and even gives the dampener the unique ability to continue functioning if the tab breaks off.
  • Weighs only a tiny 1.9 oz. heavier than the OEM dampener.


  • MADE IN THE USA with 100% domestic materials and labor!
