What it does density oilabsorbent sponge rings that capture and hold fork oil to maintain consistent lubrication of the front fork. Reduce metalonmetal contact and prevent premature wear, helping extend the service life of your equipment. Key benefits Improved lubrication: sponge stores and releases oil where the fork needs it, smoothing movement and reducing friction. Wear protection: continuously moisturizes seals and sliding surfaces to minimize abrasion and leakage. Reliable performance: imported, density sponge offers strong oil absorption and longlasting storage capacity. Compatibility and sizes Available sponge diameters: 32 mm, 34 mm, 35 mm, 36 mm. Select the sponge diameter that matches the inner tube diameter of your fork. For example, if the inner tube is 30 mm, select the 30 mm sponge diameter for fit and performance. Material and construction Made from density, imported sponge material designed for repeated oil uptake and release without rapid degradation. Engineered to fit inside the fork tube to act as an internal oil reservoir and wiper. Typical applications Routine fork maintenance: install or sponge rings during service to maintain proper lubrication and reduce seal wear. Offroad or trail riding: helps keep forks lubricated under heavy use, where frequent seal drying or contamination is common. Older forks or equipment with minor oil migration: provides supplemental oil retention to improve damping consistency. Why choose this product Practical, componentlevel solution that addresses lubrication and wear at the source inside the fork. Broad size options to match different fork inner tube diameters and ensure a proper fit. Durable, density sponge material for dependable oil absorption and retention. Compatibility note: choose the sponge diameter that corresponds to your fork's inner tube diameter to ensure correct fit and function.
