New production early AMF Ski-Daddler, and AMF Harley Davidson snowmobile urethane drive sprockets. Price is for two pieces, enough for one axle. These are made in the USA, and are show quality, quiet running, perfectly detailed from NOS original pieces, and guaranteed not to crack. Urethane is much more durable than the original sprockets. These have been tested in 20 below weather. These should fit all 9 tooth AMF models with various part numbers. These should also work as rear track guides on the early Ski-Daddlers. 
These will not fit the AMF Ski-Daddler XX models with the cleated tracks, but we have those in the Raider drive sprocket listing. Listing and price is for two sprockets. If you order more pieces, the shipping cost can be adjusted, or overages refunded. 
See our other auctions for more NOS, new and used Raider parts, including new Raider, Polaris, Ski-Daddler, and AMF Harley Davidson drive sprockets. The metal hub assembly is not included. It is only shown to show how well these fit the drive axle hub assemblies. Use the measurement photos to check your application. 
Thanks.
