Engineered specifically for the heavy-duty gearboxes found in classic Polaris Sportsman, ATP, and Magnum models, this kit is the professional’s choice for addressing oil weeping and visible leaks.

This kit is a direct replacement for original hardware, offering a reliable barrier against water ingress and oil loss.

Moto-House MX Pro Tip:

On these classic Polaris Twin models, the transmission output seals are often exposed to mud, grit, and tangled tall grass, which can tear the seal lip over time. If you see oil collecting on the skid plate or the rear of the engine cases, it’s time for a refresh. When installing the MOOSE OFFROAD 25-7112 kit, ensure the shaft surface is polished and free of corrosion. Using a light coat of waterproof grease on the inner seal lip will help prevent damage during the first few rotations of the shaft, ensuring a long-lasting, leak-free seal.
