Pioneer Mounts offer a premium replacement solution. The only mount with the Pioneer Sure-Fit (TM) System - a process of application testing on vehicle specific fixtures that ensures a hassle-free installation. The parts are manufactured from a high-grade steel with a corrosion resistant coating or cast from a pure aluminum creating a durable housing. Each housing is then bonded with a blended rubber compound that is specific to each application (including a seamless hydraulic fill and electronic control where specified) ensuring proper absorption of vibrations.
