• Automatic Grease Level Indicator: This stainless steel trailer features a blue indicator ring that protrudes when full and retracts when grease is low, helping you avoid under-lubrication and extend bearing life without guesswork.
• Water and Dirt Protection: The trailer maintains approximately 3 psi internal pressure in the hub, creating a seal that prevents water and debris from entering even when submerged—ideal for boat trailers or wet environments.
• Universal Fit for Common Trailers: Designed specifically for most 6-bolt hubs with a 2.441-inch bore diameter, this replacement works seamlessly with standard utility, boat, and cargo trailers for reliable, everyday use.
• Premium Stainless Steel Construction: Made from high-grade stainless steel, this trailer bearing accessory resists rust and far better than plastic or aluminum alternatives, ensuring long-lasting performance in harsh outdoor conditions.
• Easy Installation and Maintenance: No special tools needed—simply press this into your hub for quick setup. Includes 4 pieces so you can service both wheels at once, saving time during routine trailer maintenance.
