For all standard and cartridge forks. Anti-wear chemistry greatly reduces friction wear in suspension tubes and sliders for longer lasting suspensions and more responsive and reliable performance. Friction modifiers increase lubricity for minimum "stiction" and for more responsive and better handling suspension over irregular terrain. Viscosity stability provides long lasting and consistent performance and response, even as the suspension heats up. What's in the box 1 x 1lt Bottle - Fork Oil 5W
