Upgrade your drivetrain performance and reliability with our Hardened Tool Steel Jackshaft Sprocket, designed for maximum longevity and consistent power transfer. Built for riders who push their bikes in real-world conditions — trails, street, supermoto, stunt, and race environments — this jackshaft sprocket offers significantly improved durability over soft or cast steel alternatives.
Each sprocket is manufactured from high-grade hardened tool steel, ensuring resistance to wear, tooth rounding, chain stretch damage, and high-load torque forces. The sprocket is then treated with a black oxide coating to protect against rust, moisture, and corrosion — making it ideal for wet weather, mud riding, and frequent washdowns.
Every sprocket comes pre-installed with a new jackshaft oil seal, eliminating the need to reuse worn components or source replacement seals separately. This ensures a proper leak-free seal and long-term drivetrain reliability.
The 13-tooth option is the OEM stock size, providing factory power balance with strong acceleration and torquey low-end response. The 14-tooth option increases gearing, offering higher top speed and reduced RPM at cruising speeds, which can extend range and provide a smoother ride during longer distances or street commuting. However, increasing the tooth count will reduce torque, meaning slightly less punch off the line — ideal for riders prioritizing speed and efficiency over maximum low-end lift.
This sprocket is a direct bolt-on replacement, requiring no modification and pairing cleanly with standard chain setups.
Ride harder. Last longer. Re-gear with confidence.
