Tenneco Inc. expanded its line of Monroe OESpectrum shock absorbers and struts to cover all domestic and foreign nameplate passenger vehicle models. The OESpectrum line was previously available only for foreign nameplate applications.

“Monroe OESpectrum shocks and struts have been an overwhelming success since their introduction four years ago, and service providers throughout North America have asked us to extend the benefits of this technology to all makes and models,” said Bill Dennie, director of ride control channel management at Tenneco North America Aftermarket. “OESpectrum units provide noticeably improved ride and handling characteristics as compared to conventional replacement shocks and struts, including our own Sensa-Trac products.”

According to Tenneco, most premium Monroe brand passenger car shocks and struts – including Sensa-Trac units – manufactured in the past several months have been equipped with the Twin Technology Active Control System utilized in OESpectrum units.

Tenneco noted that the unique blend of control and comfort that Monroe OESpectrum shocks and struts offers is made possible by each unit’s Twin Technology Active Control System, an internal damping approach first developed for global vehicle manufacturers. The system consists of Tenneco’s Impact Control Valve and a patented Low Speed Tunability piston design that isolates impact-related noise, vibration and harshness. This technology is available in mono- and twin-tube OESpectrum units for passenger cars, vans, light trucks, sport-utility vehicles and crossover models as well as in replacement cartridges for vehicles equipped with rebuildable strut systems.

“OESpectrum units essentially offer twice as many tuning points as conventional shocks and struts, which enables our engineers to eliminate the compromises between control and comfort in everyday driving situations,” Dennie said. “This breakthrough approach is just as beneficial in domestic vehicles as it has been in foreign nameplates.”
