Product photo of the MRP Ramp Control Cartridge for Fox forks

The all-new Ramp Control PRO upgrade cartridges pair MRP’s acclaimed Ramp Control technology with traditional air-spring volume adjustment. Ramp Control PRO cartridges feature a threaded bottom which interfaces with MRP’s Huck Puck volume spacers - also found in the Bartlett, Raven, and Ribbon SL forks. Air volume tuning allows you to dictate the baseline air-spring curve and Ramp Control provides a powerful way to control high-speed and ending-stroke performance. Together, it’s a robust package that puts you in precise control of your air-spring performance quickly and easily.


  • Adds speed-sensitive ending-stroke control and bottom-out force adjustability to compatible forks.
  • Isolate and tune bottom-out with minimal changes to initial and mid-stroke.
  • Easy installation requires little time and few tools - no lower-leg removal required!
