High-performance L-type carbon brushes specifically engineered for the 24V starter motors of T.C. (Turbocharged) Old Model heavy vehicles. These brushes are manufactured with a high-density copper-graphite composite to handle the high-voltage electrical surge and heavy cranking torque required for classic large-displacement diesel engines. The L-type configuration ensures a stable and secure fit within traditional starter assemblies, providing excellent vibration resistance and long-term reliability for heavy-duty transport.
