Moose Racing MSE25-4048 Countershaft Seal Kit with Hardened Steel Bushing

The Moose Racing MSE25-4048 Countershaft Seal Kit is a front sprocket shaft seal kit, also called a countershaft sprocket seal kit. It helps keep transmission oil in and dirt out where the countershaft passes through the engine case. Replacing a worn or leaking seal helps protect the transmission and keeps oil off the sprocket and chain.

Key Features:

• Hardened steel bushing that gives the seal a durable sealing surface
• Upgraded seal for improved sealing performance
• O-ring and snap ring or lock washer included where applicable to the application
• Made in the U.S.A.
• Suitable for street and off-road riding

Moose Racing builds its countershaft seal kits to be a complete, straightforward repair for the front sprocket area. Use it when you replace the countershaft sprocket or when you see oil seeping from the sprocket shaft.
