Available selections vary by application and length.What +2″ meansApproximately two additional inches of inner-tube length relative to the stated stock reference—not two extra inches of suspension travel or a guaranteed two-inch ride-height change. Longer tubes must be matched to the complete suspension setup. Inch dimensions shown are approximate conversions from millimeters.InstallationInner tubes only—not complete fork assemblies, cartridges, or a complete extension kit. Seals, bushings, springs, cartridges, and fork oil are separate service items. Professional installation is recommended. Match your exact model/year, the front end actually installed, and the internal suspension components before assembly.Fitment helpEmail your motorcycle year/model, installed fork, and cartridge-kit details to sales@zerohourmoto.com.
