Moose Offroad 13T front (countershaft) sprocket for 420 chain, built from heat-treated chromoly steel for long wear life and precise OEM-style fit. Nickel coating improves corrosion resistance and lubricity for smoother, more reliable drivetrain performance.
Upgrade durability and keep your drivetrain running smooth with the Moose Offroad front (countershaft) sprocket. Machined from high-tensile, impact- and wear-resistant chromoly steel, it’s designed to minimize deformation and maintain consistent power transfer over time.
Its broached inner splines maximize spline-to-countershaft contact, helping distribute driveline forces across the largest possible surface area—reducing localized wear and improving long-term fit. After heat treatment, the sprocket is finished with a nickel coating for added corrosion resistance and improved lubricity, making it a strong choice for harsh off-road conditions.
Note: If ordering a size larger than stock, ensure there is sufficient clearance on your model.
