About This

• This sprocket has a 9.8mm offset (Offset is measured from the sprocket bolt mount surface to the center line of the teeth.) The inner diameter of the center hole is 2-1/4"
• Fits MANY 2000+ Harley Sportster & Big Twin models using a 530 chain. NOTE: This sprocket is made to bolt up to many 2000+ Harley Sportster & Big Twin rear wheels, however, the final fitment will be dependent upon many factors of your application, so please take measurements prior to making a purchase. If your bike is stock, you still may need to double check the offset against the front sprocket.
• We also offer 48 Tooth rear sprockets as well as full conversion kits with a front sprocket and chain.
• NOTE: Remember a larger rear sprocket means more torque (geared down) and a larger front sprocket means more top end (taller gearing).
• NOTE: Because of tight clearance when using stock muffler mount or stock passenger peg mounts do not use an O-ring chain because the additional width may cause chain to wear at these components on deceleration.
• PACKAGE INCLUDES: In addition to the product listed, the package will also include a Genuine Billet Proof Designs Authenticity Sticker. Note: Units without the official Billet Proof Designs decal are not authentic and are not covered by our manufacturer warranty.
