The KONI Special Active is a frequency-selective damping shock that reads road input and adjusts firmness on the fly, tightening body control over rough surfaces while smoothing everyday ride comfort. It is a direct-fit rear shock for the Tesla Model 3 and Model Y in both rear- and all-wheel-drive forms, giving a more composed, planted feel than the factory dampers with no manual adjustment.
