This is HCI's New Single Spring Packed Assembly. 

Progressive Spring System

This System allows for Adjustable Dual Rate Spring Performance. Two Springs are Stacked and Deflect at a combined Rate. At a Point Determined by the Contact Position of the Lock Out Nut on the Threaded Body of the Shock Absorber and Separating Hardware between the Springs as Determined thru Track testing by HCI, One Spring Stops Deflecting. This Allows only the other remaining spring to deflect, It will do so at it's own spring rate. This System allows a Team to Tune the Suspension at a Relatively Soft combined rate for turn entry and Locks out on a Higher Secondary Rate for Maximum Compliance and Wheel/Tire Loading.
