ACS3 Fork Coil Conversion Kit

PLEASE NOTE: DOES NOT FIT FOX 36 E-MTB OR RHYTHM MODELS

PLEASE NOTE: DOES NOT FIT 2023 ROCK SHOX MODELS

Increased small bump sensitivity improving comfort. Increased traction improving control. All without compromising big hit performance.

Have you ever found yourself getting the sensitivity out of your air fork only to find that it's now mushy through the mid-stroke or too linear at the end of the travel causing a harsh bottom out? Or, are you over-pressurizing your air fork to eliminate that mushy mid-stroke only to find that now your fork lacks any level of bump sensitivity or initial traction?

With our ACS3 Coil Conversion Kit you'll get:

  • Smooth and supple initial coil feel.
  • Stable and controlled coil fork mid-stroke.
  • Adjustable big hit control of an air fork via our secondary Air Bump Stop Technology.

If I got a new bike, I'd buy this ACS3 kit, as I'd have a tough time getting on another air spring fork any time soon.

Specialized Status Fox 36 coil conversion

Been on multiple rides after installing new coil kit and overall I’m very happy with it. The coils ability to absorb rocks, roots and chatter is fantastic!

E.g.
it works with a 2023 pike

I got bored and decided ill try it out, low and behold it all fits together perfectly, but only the 140 works.

The ACS3 coil conversion is the best upgrade for my ROCKSHOX Pike

WOW what a difference on my ROCKSHOX Pike. I had upgraded it 2x to the new and improved seal heads which to me never made much difference. AC3S Installation was easy since I had been in my fork several times beforehand. The AC3S conversion makes a huge improvement over air. No more jack hammering on washboard surfaces. Way more plush than air. This is what suspension should feel like. Price was right too thanks to PUSH!!! Now I need to save up for a coil rear shock.
