Key Product Features

The All Balls 25-1150 Wheel Bearing Kit is built to higher-than-OEM standards to handle the "difficult operating environments" of off-road riding.

• Kit Contents: Includes two high-speed bearings and the necessary double-lip seals to fully refit one wheel.

• Precision Engineering: Bearings are manufactured to ABEC-3 precision standards to ensure low drag and smooth rotation.

• Superior Sealing: Uses TC Nitrile Elastomer seals with stainless steel garter springs. These are specifically designed to keep water and grit out while retaining lubricant.

• Premium Lubrication: Pre-packed with Chevron SRI-2 grease, which contains special rust and oxidation inhibitors.

• Durability: Developed in partnership with KML Bearing for maximum service life in mud and water.

Installation Note

When replacing these bearings, it is critical to inspect the bearing carrier for any scoring or damage. If the old bearing "spun" in the housing, the new kit may not seat properly. Clean the hub thoroughly and apply a light film of waterproof grease to the outer edge of the seals to aid installation and further block moisture
