Moose Racing MSE25-4016 Seal Kit Countershaft Kaw

The Moose Racing MSE25-4016 countershaft seal kit (also called a front sprocket shaft seal kit or counter shaft seal kit) is a repair kit for oil leaking from behind the front sprocket. It replaces the worn seal and the bushing surface it runs on, so you can fix the leak without a lot of disassembly.

Key Features:

• Hardened steel bushing that resists wear and the seal damage it can cause
• Upgraded seal material for longer service life
• Includes O-rings and a snap ring or lock washer as needed to complete the repair
• Pre-packaged kit, so the parts you need come together
• Made in the U.S.A.

Replacing the countershaft seal and bushing together restores a reliable oil seal at the output shaft. This helps keep oil off the sprocket and chain.
