Designed for the motocross world, this KYB dust seal protects the shock absorber shaft from mud, sand, and debris during off-road outings. A compact and precise replacement part, it fits on shafts with a diameter of 16 mm and nests into a housing of 31 mm diameter for a useful height of 11 mm — ideal for maintaining sealing and limiting wear on the seals around the shock absorber body.
