An electric air pressure rod includes lifting rod, gas spring, nut and driving unit. Lifting rod includes outer tube of lifting rod and inner tube of lifting rod, wherein outer tube of lifting rod can move along the axial direction of the inner tube of the lifting rod. Gas spring is arranged inside lifting rod and is included of thread tube with thread on outer wall, piston as well as piston rod, wherein distance between piston rod as well as inner tube of lifting rod remains constant, wherein piston is located at free end of piston rod and in the sliding seat with inner wall of thread tube, wherein seal guide assembly is provided between piston rod and thread tube. Nut is adapted to the thread tube. Driving unit is fixedly arranged in outer tube of the lifting rod and serves to drive the thread tube in rotation.

Described herein is a shock adjuster comprising a remote pulley, a pulley shaft, wherein the pulley shaft is coupled to the remote pulley at a first end, wherein the pulley shaft is coupled to an air spring cam shaft at a second end, an air spring needle, wherein the position of the air spring needle is determined by the position of the air spring cam shaft, wherein an air spring shim is engageable with the air spring needle, an open mode adjuster, a compression cam shaft, wherein the compression cam shaft is coupled to the open mode adjuster, a compression needle, wherein the position of the compression needle is determined by the position of the compression cam shaft, and a shim, wherein the shim is coupled to the compression needle, wherein the shim is fit to open or close at least a main port in a piston.

A check shim style electronic modal base valve is disclosed. The check shim style electronic modal base valve includes a motive component, a controller communicatively coupled with the motive component, and a control valve having a lead screw is coupled with the motive component. The controller is configured to control an operation of the motive component, wherein a movement of the motive component is configured to cause the control valve to adjust a flow rate for a flow path through the check shim style electronic modal base valve.

An electronic modal base valve is disclosed. The electronic modal base valve includes a motive component, a controller communicatively coupled with the motive component, and a control valve coupled with the motive component. The control valve includes a multi-state rotary spool. The controller is configured to control an operation of the motive component, wherein a movement of the motive component is configured to cause the control valve to adjust a flow rate for a flow path through the electronic modal base valve. The multi-state rotary spool has a softest setting, a lockout setting and at least one intermediate setting for the flow rate along the flow path.
