Building on long experience with heavy-duty suspension systems, Hendrickson designed its new PRIMAAX air-suspension specifically for the demands of vocational and heavy haul truck and tractor applications. The PRIMAAX design employs a unique geometry that reduces suspension-induced driveline vibration, resulting in greater driver comfort and improved driveline-component life. The system is said to be especially effective when trucks use high-torque engines. List price depends on the OEM, but is in the range of $3,000.
