Ditch that belt and go with a traditional 530 rear drive chain setup on your 2004 & Up 1200 Sportster. These sprockets keep the same gearing ratio as your stock drive belt setup on an 1200. For use with a stock rear wheel (this is not for a wide tire conversion). Consult your manual on removing your pulleys, and simply install the front sprocket, and the spacer and rear sprocket with the included proper length chrome plated hardware. 530 Chain not included, supply your own or choose one from here at Lowbrow and we will pluck it gingerly from our shelves and lovingly though expediently deposit it into your package and send it on it's way. But I digress.
The transmission and rear sprockets as well as the included new rear wheel sprocket hardware are all Made in the USA! The front sprocket is high quality nickel plated Chromoly steel, and the rear sprocket is 7075-T6 certified aero space grade aluminum for long life and light weight.
NOTE: These are made for use in a stock Sportster frame or a frame or hardtail which uses stock spacing (such as the David Bird hardtails which use the stock rear wheel assembly, brake, and axle spacers). If the frame you are using is a different axle plate spacing(width) or you are using a non-stock wheel this may affect the rear sprocket alignment. This is for use with a stock with wheel, and is not for a wide tire conversion.
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.
