MegNeg Upgrade Kit

Introduced with the Rockshox 2020 lineup, the MegNeg upgrade kit allows you to tune your shock exactly to your ride. The MegNeg air can allows more mid-stroke support, a plusher initial feeling and more bottom-out force while using less tokens; all thanks to an even larger negative volume. Since the MegNeg is empty of spacers, you'll see more negative air space, which helps reduce the amount of force it takes to get into your bike's travel.

  • An upgrade kit that gives you more tunability
  • Includes air can, tokens, seals and decals
  • Compatible with Deluxe and Super Deluxe shocks

Huge difference in Superdeluxe Select

I've used it several times
True to size
5` 8"
185 lbs

Upgraded my Rockshox Superdeluxe Select with the Megneg can. Immediately noticeable when riding over chatter like roots, rocks and such at speed. I’m 185 lbs. The Megneg can requires more PSI so I’m running it at about 215psi to achieve 30% sag. I then added 1 (supplied) volume spacer to the negative air chamber and performance improved even more. Very planted, controlled feel yet still plush over rough sections AND sits much higher in its travel. Super impressed and Well worth the price !!!!


I have a Santa Cruz Hightower that is 2020 and want to make sure I am getting the right MegNeg. My eye to eye is 210 and stroke is MY20 52.5mm and MY21 55mm
