The Xtreme 142MSSF TFX Suspension Technology, No standard! Experience intelligent suspension with the TFX The Xtreme (142MSSF). This advanced rear shock absorber features our exclusive Dynamic Valve System, which automatically adjusts damping force in real-time for superior traction and bottom-out resistance, making it the smartest choice for race suspension and unpredictable terrain. Built for ultra-high performance! This shock absorber is for the rider who is looking for the highest performance, durability, control, and best refined tuning options. It doesn’t matter if you use it for Adventure riding, Baja racing, Endurance racing, or recreational use—this shock is a winner! Every TFX Xtreme shock features heavy-duty damping valving specifically developed for your application, and the spring is selected for your weight and intended use. Our modular assembly system allows us to make special requirements (like different spring or anodizing color) or changes in length as second nature. The upper mount consists of a full CNC-milled aluminum 7075 part. It serves as a connection to the compression reservoir which gives the shock extra cooling and houses the setup screws for the high- and low-speed compression adjustment. Revolutionary Dynamic Control Our new Dynamic compression valve adjuster reacts instantly with oil flow and pressure. This means when you need a stiffer or softer damping force, the Dynamic Valve System automatically adjusts the oil flow to compensate. It dynamically governs compression for instant results, delivering much better traction, improved bottom-out resistance, and unmatched versatility in your suspension. Each shock also features our fully adjustable rebound damping. It gives you the ability to fine-tune your rear suspension with precision. They come with 1 or 2 springs. The spring preload can be set for extra loading by using the included C-spanner.
