These precision-machined shock pistons are meticulously engineered to fine-tune the damping characteristics of Kyosho's big bore shock absorbers, primarily found on the Inferno MP777 series off-road buggies. Crafted from a durable, low-friction composite plastic, they ensure consistent oil flow and smooth suspension action across varying track conditions, resisting wear and providing a tight seal. Replacing existing pistons with this specific 1.4x5 hole configuration allows racers and enthusiasts to precisely adjust their vehicle's responsiveness, thereby enhancing stability over jumps, improving traction through rough terrain, and adapting the setup to diverse track layouts.
