    About the Piston

    Advanced Low-Friction Performance

    The Throttlefinger Flat Shock Pistons boast a 15.8mm outer diameter and are precision CNC machined for optimal fit and finish. Their low-friction construction results in ultra-smooth shock action, enhancing control and handling on a variety of track surfaces. Each piston is laser-etched with its size and hole configuration, allowing for quick identification during tuning or maintenance. With excellent dimensional stability and resistance to oil-based fluids, these pistons provide long-lasting, consistent performance for competitive RC drivers.
