Reverse cable for Hammerhead Junior, SS150, Standard 150 and push-button start GTS150. The length is roughly 61" long with round balls on both ends and used only for 150cc engines with external reverse boxes.  This reverse cable also fits Kasea and Carter Brothers and very possibly several other 150cc gokarts out there.

If the 150cc engine has internal reverse with F/N/R gears you will need to order reverse cable (part # 14456).  The F/N/R units also have 2 reverse cables.
