No. We designed the Spectral:ON’s kinematics with the spring curve of an air shock in mind. Moreover, coil shocks are not ideal in designs that use clevis-mount shock extensions and rockers. The forces transferred (in such a design) to the smaller-diameter damper shafts used in coil shocks is quite high and can lead to shock failures. Air-sprung shocks are better suited to this design because they utilize larger-diameter damper shafts that better withstand those forces and thereby increase shock life.
