Timoney 87150 Series ISAS Off-highway

Timoney developed the world's first independent suspension for Airport Rescue Fire Fighting (ARFF) trucks in the 1970’s and in the decades since has continued to lead the evolution of Independent Suspension systems for off-highway trucks. Notable milestones include the Timoney suspension system for the P 23 8x8 ARFF, the first USAF fire truck to have independent suspension. In 2000, Timoney introduced the latest stage in this evolution, the 87150 Series ISAS - rated as one of SAE Off-Highway’s Top 20 Products for 2004.
