Moose Racing MSE25-4013 Seal Kit Countershaft Kaw

The Moose Racing MSE25-4013 Countershaft Seal Kit (also called a counter shaft seal kit or front sprocket shaft seal kit) is made for Kawasaki powersports engines. It stops oil leaking from behind the front sprocket. The countershaft seal is the seal on the front sprocket output shaft.

Key Features:

• Pre-packaged repair kit that replaces a worn or leaking countershaft seal
• Includes a hardened steel bushing and an upgraded oil seal
• Includes an O-ring and a snap ring or lock washer where the application calls for them
• Simple installation, with the sealing hardware in one kit

If you see oil seeping around the countershaft sprocket, replacing the seal and bushing is often all that is needed. This kit helps restore proper sealing and protects the engine from oil loss.
