Moto-House MX Pro Tip:

On the 2009-2011 Sportsman XP models, the transmission seals are often subjected to heavy debris and water ingress. If you notice a "wet" spot on your garage floor or grime buildup around the transmission output, it is time for a refresh. When installing the MOOSE OFFROAD 25-7111 kit, we recommend thoroughly cleaning the shaft surfaces and using a small amount of waterproof assembly grease on the seal lip to prevent "dry start" damage. Always check and top off your transmission fluid after installation to ensure your gears are fully protected.

FAQ Questions

Q) Does this kit include transmission bearings?
A) No, this is a seal-only kit (25-7111) designed to address external oil leaks. If your shaft has significant play, you may need to purchase bearings separately.

Q) How do I know if I need new seals?
A) Check for oil accumulation around the transmission casing or a low reading on your transmission dipstick. Early intervention prevents internal gear damage.
