Assault Industries reservoir expansion caps increase the nitrogen volume in the shock absorbers. The result is a more consistent feel throughout the entire range of travel.
The caps are CNC machined from 6061 T6 billet aluminum to be as light and efficient as possible. The unique design features cooling fins to help with heat dissipation during aggressive use. High pressure nitrogen purge/fill valves make it easy to service shocks.
Note: These caps have been tested to fit most Fox brand external shock reservoirs. They may fit others. Additional compatibilities will be announced when available.
