I originally installed my first ACS-3 on a 2019 Fox36 170mm. I’m still running that fork. Last year on my SB165 and this year on my SB140. Absolutely love it and easily maintained with routine annual maintenance. I also swap the coils when moving from one bike to another (hence the Blue Coil purchase). Also easy to do. I’ve since bought another for my son’s bike. I am getting ready to have a Lyrik with the HC97 converted from air to an ACS-3 Coil next month. Dropping the 160mm Lyrik from 160mm to 140mm coil for another bike of mine. A downcountry ride where this setup will fit well. Truly love my bikes with an ACS-3 upgrade.
