Function and benefit density oil absorbent sponge rings that store and retain fork oil to lubricate the front fork, reduce metaltometal contact, and slow wear on fork seals and inner tubes. Extends equipment service life by maintaining a consistent oil film and reducing abrasive contamination. Key features Material: Made from imported, density sponge for reliable oil absorption and storage. Performance: oil uptake and retention to keep lubricating oil available where the fork needs it most. Compatibility: Available sizes 32mm, 34mm, 35mm, and 36mm to match common front fork inner tube diameters. Easy selection: Choose the sponge diameter that matches your fork inner tube for a snug fit and performance. For example, if the inner tube is 30mm, select the 30mm sponge diameter for fit and performance. Why you need it Prevents premature seal and tube wear by holding oil at the contact surface. Reduces maintenance frequency and helps preserve suspension performance over time. Simple, costeffective part to protect expensive fork components. Typical applications Motorcycle front forks (street and sport bikes) for improved seal lubrication and longer seal life. Offroad and dirt bikes to help control contamination and maintain damping performance in harsh conditions. Small ATVs and scooters with telescopic forks where consistent lubrication reduces service needs. Installation and use tips Measure the inner tube diameter and select the matching sponge size for a secure fit. Inspect and sponge rings during routine fork maintenance or when oil absorption capacity diminishes. Compatible with standard fork oils; avoid aggressive solvents that can degrade the sponge material.
