The Meritor QP6-1658-178 or QP61658178 is a genuine OEM Camshaft Brake Assembly designed for heavy-duty air brake systems. The S-cam camshaft is the primary actuator in drum brake foundations - when the brake pedal is applied, the camshaft rotates and forces the brake shoes outward against the drum. This assembly is sourced directly from Meritor, the original manufacturer, making it a direct-fit replacement for applications specifying part number QP6-1658-178. Pro Gear and Transmission carries genuine Meritor brake components. Call us to confirm proper fitment for your specific axle and brake configuration.
