The Warp 9 Racing Ultra Bee Jack Shaft Sprocket is a durable replacement/upgrade sprocket designed for Ultra Bee applications, built to handle drivetrain load while offering a choice of gearing. It’s made from hardened tool steel for longevity and finished with a black oxide coating to help protect the surface. Each sprocket includes a new jack shaft seal that comes installed in the sprocket for convenient service. Choose the 13 Tooth(Stock) option to match the OEM size, or step up to the 14 Tooth option to change the final drive feel by lowering RPMs for more top speed and extended range, with the tradeoff of reduced torque.
Constructed from hardened tool steel for longevity, this jack shaft sprocket is built for long service life under real drivetrain use. It’s a straightforward way to refresh worn sprocket teeth and keep your Ultra Bee’s power delivery consistent over time.
A black oxide coating adds a protective finish to the sprocket and gives it a clean, subdued look. This surface treatment complements the hardened steel construction and is well suited to the demands of a jack shaft sprocket.
A new jack shaft seal is included and already installed in the sprocket. That means fewer separate parts to source during service and a quicker, more convenient installation when replacing the jack shaft sprocket.
