The 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.

• Twin Technology - 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.
• All Weather Fluid - Contains special modifiers to reduce friction and ensure smooth rod reaction.
• Rod Displaced Valving - Tuned specifically for each application, this valving automatically adjusts to road extremes to provide consistency and ride comfort.
• Fluon Banded Piston - The fluon band provides consistent sealing between the piston and pressure tube which delivers better control and increased durability
• Hardened & Chromed Plated Piston Rod - Long service life.
• Notrogen Gas Charged - For improved ride and handling, helps maintain tire to road contact by reducing aeration.
• Unique Rod Guide & Single Lip Seal - Bronze reinforced rod guide bearing and special seal provides longer service life and consistent performance.
