Monroe OESpectrum struts are engineered specifically for foreign nameplate vehicles and feature the latest global original equipment valving technologies. Developed through years of research and on-vehicle testing, Monroe OESpectrum units provide an unprecedented level of handling precision and control while filtering out the ride harshness commonly encountered on many foreign nameplate applications. This unique blend of control and comfort is made possible through Tenneco's 'Twin Technology Active Control System', an exclusive internal damping control technology first developed for leading global vehicle manufacturers. Tenneco's Twin Technology consists of its latest Impact Control Valve (ICV), which delivers exceptional control under virtually all driving conditions, and a patented Low Speed Tunability (LST) piston design that isolates impact-related noise, vibration and harshness.
