PUSH Industries ACS3 coil spring kit – A spring in the right direction?

Ever since the release of their drool-worthy ELEVENSIX rear shock, PUSH Industries have been a big name in the MTB suspension industry. Their newest product is the PUSH Industries ACS-3 (Advanced Coil System) a drop-in coil spring kit for Fox 36s and RockShox Pikes that PUSH claim lets you combine the supple feel of coil with the progressivity of an air cartridge to prevent harsh bottom outs.

Here’s what PUSH have to say about it:

The new PUSH ACS-3

Introducing the Push Industries ACS-3, a coil spring conversion kit from PUSH Industries designed to transform front suspension performance. Built in-house with PUSH’s hallmark attention to detail, the ACS-3 replaces the stock air chamber of a Fox Racing Shox 36 or RockShox Pike with a proprietary coil spring mated to a pneumatic bump stop. The result? Supple, linear suspension throughout the early and mid-stroke of the fork with an air cartridge to prevent bottom out at the end of the fork’s travel.


  • MSRP $389
  • Supplemental spring MSRP $80
  • Manufactured entirely in the USA
  • 2015 through 2017 Fox 36 Float or Talas 160mm kits are available NOW. Fox 36 140, 150 and 170mm travel models and 2018 140-170 kits arrive in late July.
  • Rockshox Pike kits Coming Soon.
  • RockShox Lyrik/Yari will NOT be offered due to the small inside diameter of the stanchion tube.

Complete Service Kit

Alongside the ACS-3 PUSH have also come up with a Complete Service Kit to keep your forks feeling buttery smooth. These kits will retail for $105 and include new seals, a Colorado made seal driver, and enough oil for up to five services. Extra seals can be purchased for $36. PUSH claim that their seals effectively double the service intervals, keeping your forks plusher for longer.
