Dynamic Friction's True Balanced line is an OE replacement drum, cast and then finish machined to the tightest tolerances for a direct bolt-on fit. True Balanced refers to the process: every drum is precision cut and mill balanced on dedicated vertical turning centers and balancing machines rather than a shared rotor line, so the imbalance and runout that reach the driver as vibration and pedal pulsation are corrected before it is boxed. A high temperature black coating rated to 120 hours of salt spray protects the casting.
