Product Description
The CARDONE 20-8715 remanufactured power steering pump is designed to restore smooth, reliable steering performance for heavy-duty GM trucks and commercial chassis vehicles from 1980–1991. Each pump undergoes extensive remanufacturing and is meticulously tested to ensure long-lasting durability and OE-level performance.
Every unit features 100% new premium HNBR seals and O-rings, offering superior high-temperature resistance to prevent fluid leaks. Critical internal components—including campacs and spool valves—are triple-tested to ensure reliability under demanding operating conditions. Final assemblies are computer-tested to validate pressure output, flow rate, bypass operation, steering effort, and acoustic performance.
CARDONE’s remanufacturing method also reduces energy and material waste by up to 80%, making this pump an environmentally responsible replacement choice.
