Information on "Strut-mount" bikes and FOX/Marzocchi coil shocks

Mountain bikes (MTB) and electric mountain bikes (eMTB) with "strut-mounts" such as those shown below require additional evaluation when configuring with a FOX or Marzocchi aftermarket coil shock.

When evaluating the purchase of a FOX or Marzocchi aftermarket coil shock (DHX2, VAN, or BOMBER CR) on a "strut-mount" MTB or eMTB frame, FOX and Marzocchi recommend the following:

  • Please check OEM bike owner's manual for confirmation of coil shock compatibility.
  • DO NOT exceed the shock stroke or max strut length* listed in the table below (consult your OEM if unsure).
  • Confirm shock length/ shock stroke for the specific frame.
  • Only "metric-length" shocks should be used.


Shock Stroke  Max Strut Length*
Standard Eyelet  Trunnion Eyelet 
40mm-45mm 118mm 76mm
50mm-55mm 98mm 56mm
60mm-65mm 72mm 36mm
70mm-75mm 37mm 16mm

*Strut length is the distance between the axis of pivot and the axis of the shock mount
