Get More Out Of Your Suspension

Ramp Control is an air spring upgrade for most Rock Shox and Fox forks that provides on-the-fly ride tuning and improved suspension performance in a simple to use and easy to install package. Ramp Control is the BEST way to tune your air fork.

Why Use Ramp Control

Increased Traction

Ramp Control gives you extra grip on technical terrain.

Progressive Bottom-Out Support

Ramp Control protects against bone jarring bottom-outs.

On-The-Go Adjustability

Ramp Control adjusts performance with the turn of a knob.

Ramp Control vs Volume Spacers


Tokens and volume spacers aren’t friendly to on-trail experimentation and tuning. Ramp Control provides precise air spring tuning with a 16-position dial, allowing you to perfectly dial in your fork for any trail – in seconds.


Volume-reduced air springs worsen small bump performance and buck you off line in slow, technical riding. Ramp Control’s speed-sensitive design gives you additional spring support only when you WANT it.


Adjusting volume spacers or tokens also requires changes to air-pressure and damper settings. Ramp Control provides air spring tuning that is independent of other fork settings.

More Info



Volume adjustment spacers change the shape of the air-spring’s curve throughout the entire travel range, regardless of velocity. Aside from the slight change resulting from the volume of the cartridge itself, the Ramp Control upgrade affects only the ending stroke spring curve - as its damping effect is velocity-dependent. This portion of the curve represents intense, sharp hits and big events, like landing a sizable drop or plowing through a rock garden. Without Ramp Control, your fork’s behavior in these circumstances has been compromised by your desired feel elsewhere in the stroke. With Ramp Control, you can tune the general feel of your fork through its air-pressure and damper settings, and isolate big-hit performance and bottom-out with the Ramp Control adjustment.

Inarguably, convenience is one of the biggest benefits of the Ramp Control cartridge versus internally-accessed volume adjustment components. Internally-accessed spacers aren’t friendly to on-trail experimentation and tuning - requiring bulky tools and a clean environment to utilize. With Ramp Control, experimentation is so simple it’s encouraged! The powerful range of Ramp Control is harnessed through a simple 16-position knob with clearly defined detents. That enables you to arrive at your base setting in just one ride on a familiar trail, whereas internally-accessed spacers would necessitate a trial and error approach - several rides followed by garage or shop sessions - to get to the same point.



Unless you ride just one trail, the air-spring volume you’ve so carefully tuned with internally-accessed volume spacers is probably not ideal for all your adventures. A trip to the bike park might reveal, for example, that more support would be welcomed when the features and drops get bigger and trails get steeper than those found on your local go-to. If you have extra spacers and the necessary tools on hand, and don’t mind burning time that could otherwise be spent riding the lift-accessed terrain you just paid for, you could get the needed support. Or, in just seconds, you could add more Ramp Control and keep the good times going. Whether it’s a new-school flow trail or near vertical DH course, Ramp Control gives you immediate control of the terrain at hand - of particular benefit to time-crunched enduro fans tasked with practicing and racing multiple, varying stages.

Reviews and Awards

Trail Features

"For the riders out there, looking to get the absolute most from their bikes, this is definitely an upgrade worth looking into."

The Loam Wolf

"The increased small bump sensitivity allows me to take advantage of faster rolling sections, and the bottom out protection helps me manage the larger hits with my 140/140 travel."

Bike Rumor

"You can take advantage of your full air volume for a supple ride and small bump finesse, but still control the ramp on bigger, high speed hits to prevent harsh bottom out." 


"This makes tuning far faster, more convenient and subtle than using a bag of volume spacers."
