Garage Files: Swapping Volume Spacers in Your Fox Suspension
Swapping Volume Spacers in Your Fox Suspension
Dialing in the air volume on your suspension can make a big difference in the ride. Air volume has a big effect on the progressiveness of your suspension, so adding or removing spacers will change how your suspension feels at the bottom of its travel. By adding these volume reducers, you can force your fork or shock to resist bottoming out. For aggressive riders, this is a valuable tuning option. Fortunately, Fox offers some of the most tunable pieces of suspension on the market. In this “Garage Files” we will show you how to install volume reducers in both your fork and shock.
1 Dialing in your air volume is one of the easier procedures with your suspension, but you do need a few tools. For this you will need a ratchet, Fox Fluid, socket fittings for the air spring, volume spacers and, in some cases, a strap wrench.
3 Unthread the air-spring cap and attach a shock pump to release all of the air pressure in the fork. Before releasing the air, record your current air pressures so you can duplicate them after the volume spacers are installed.
9 Use the ratchet to tighten the top cap down all the way. The top cap should be torqued to 24.8 newton meters, which is tighter than you can get with your fingers, but not as tight as you could go with a ratchet.
11 Now, we’re going to work with the rear shock. The process is very similar and can usually be done with the shock still on the bike. Clean the air can with isopropyl alcohol to make sure no contaminants will get inside.
14 With the air can unthreaded, pull it down all the way to the end of the shaft body. You might feel a little resistance from the seals. Slide the bottom-out bumper and plate away from the eyelet assembly. You can use your fingers or blunt-ended tool that won’t scratch the surface of any of the parts.
