Product Description

Ramp Control Upgrade Cartridge for Fox 32, 34, 36

  • Adds speed-sensitive ending-stroke control and bottom-out force adjustability 
  • Just 55 g! Lighter than most air-spring assemblies with more than two tokens.
  • Isolate and tune bottom-out with minimal changes to initial and mid-stroke.
  • Bring your tuning to the trail and out of the workshop!
  • Easy installation requires little time and few tools - no lower-leg removal required (EXCEPT FOR Fox 36 which requires removal of lower legs and air assembly).

Fox 34, Version A

     ...will fit 2016 and newer Fox 34 Float forks with the FIT 4 and Grip dampers. Recommended for 140-160mm 29”, 27.5+, and 27.5” forks.

Fox 34, Version B (long-body)

Fox 32, Version C

     ...will fit 2016 and newer Fox 32 Float forks with the FIT 4 and Grip dampers. Recommended for 100-130mm 26”, 27.5” and 29" forks.


  • Not recommended for 80-90mm forks
  • Not compatible with 140-150mm forks
  • Not compatible with Fox 32mm Step Cast forks

Fox 36, Version D

This new model goes beyond our previous offerings and includes parts
to convert the stock air-spring into an independent positive and negative chamber arrangement similar to the Fulfill™ spring found in our Ribbon and 2017 Stage forks. Once installed, you can now vary the pressures in your two chambers; increasing your negative spring rate to improve small bump sensitivity (a common complaint with the stock spring). This, in addition to the control you have over bottom-out and ending-stroke performance, gives you a radically more sophisticated air-spring that’s incredibly straightforward to tune and adjust!

     ...will fit 2015-2017 Fox 36 Float forks with the FIT 4, RC2, and Grip dampers. Recommended for 140-180mm 29”, 27.5+, and 27.5” forks.


Fox 36, Version F

Version F is a cartridge-only kit suitable for 2018 Fox 36 forks of all travel and wheelsize options. A revised air-spring design in Fox's latest 36 makes the Fulfill™ spring conversion included in Ramp Control Upgrade Version D incompatible. 

    ...will fit 2018 and newer Fox 36 Float forks with the FIT 4, RC2, and Grip dampers. Recommended for 140-180mm 29”, 27.5+, and 27.5” forks.  Fits Rhythm Forks.

Customer Reviews

"Completely transformed the fork, brilliant upgrade. "

"Nice! Ruth @TFT"
"Excellent product, supplied by TF tuning, very good price and quick delivery. The ramp controller is easy to install, and the pack comes with the required slick honey for installation. The controller allows you to fine tune the progression of the fork replacing the need for tokens/volume spacers, and the need to add and remove the tokens, as this can be done on the fly with the adjustable knob. Overall excellent product and great service. Highly recommended"
