A clutch assembly is provided comprising a clutch housing having a clutch housing length. A central piston chamber is positioned therein and feeds a pressure chamber. A translatable clutch piston is in communication with the pressure chamber and is movable between a piston neutral position and a piston activated position in response to air pressure fed into the pressure chamber. A rotating drive shaft is positioned within the clutch housing. A cone clutch element is moved from a clutch engaged position to a clutch disengaged position in response to the translatable clutch piston moving from the piston neutral position to the piston activated position. The cone clutch element engages the rotating drive shaft when in the clutch engaged position. A clutch spring biases the cone clutch element into the clutch engaged position with a clutch engagement force. The clutch spring has a primary spring ratio of a wire diameter to a spring diameter optimized such that a maximum spring force is achieved while minimizing the spring length.
