Abstract: An airshock assembly is disclosed. The airshock assembly includes a shock absorber an airspring, and an air compressor assembly. The airspring is axially coupled with a portion of the shock absorber and used to modify a ride height of the shock absorber. The air compressor assembly is coupled with a portion of the shock absorber. The air compressor assembly is used to modify an air pressure in the airspring without requiring the airshock assembly to utilize an air reservoir.
