Available Options

By creating a more progressive spring curve, this upgrade softens small chatter while still providing the support needed for bigger hits and aggressive riding.

Frequently Asked Questions

  • Will these shocks work if I’m not running High Lifter Long Travel? Yes, these upgrades can still be installed on a machine with a different suspension setup. However, since they are specifically tuned and tested with High Lifter Long Travel systems in mind, overall ride quality and performance may vary depending on your setup.
  • What type of riding benefits most from custom tuned shocks? Custom tuned shocks improve performance across a wide range of riding styles. Trail riders will notice better small bump compliance and reduced fatigue, while aggressive riders benefit from increased control and bottom-out resistance. Mud riders will also see improved traction and stability thanks to better weight transfer and control in rutted or uneven terrain. No matter how you ride, properly tuned suspension helps your machine stay more planted and predictable.
  • Can I still install the upgraded Shock Therapy Suspension with High Lifter Portals? Absolutely, Shock Therapy actually validated their shock tuning on machines running High Lifter Long Travel and High Lifter Portals. This allowed Shock Therapy to ensure you get the best ride quality whether you are strictly running our long travel or also have a set of portals for that extra ground clearance.
