Units’ Exclusive Twin Technology Active Control System Offers Precise Control Without Unwanted Harshness Common to Millions of Vehicles

Las Vegas, NV, Nov. 1, 2011 – Tenneco Inc.’s (NYSE: TEN) Monroe^® OESpectrum^® replacement shock absorbers and struts have proven to be popular among installers and consumers who have long sought a ride control solution for foreign nameplate passenger vehicles that provides exceptional handling precision without unwanted noise, vibration and harshness.

Introduced earlier this year, Monroe OESpectrum units feature an exclusive Twin Technology Active Control system that helps deliver original equipment-style control while filtering out the road-induced NVH commonly encountered on vehicles with lighter-weight suspensions and low-profile tires. This solution, now available for virtually any popular late-model foreign nameplate passenger vehicle, is based on advanced valving technologies originally developed for Tenneco’s global OE customers.

“The purpose of the OESpectrum product line is to help Monroe customers – distributors and installers – grow their shares of the foreign nameplate ride control market,” said Bill Dennie, director of ride control channel management, North American Aftermarket, Tenneco. “To achieve this goal, we needed to create a technology that offers clear advantages over other ride control products for this market segment. Our pre-launch field testing indicated that OESpectrum was the solution we were looking for, and our first year in the market has absolutely exceeded our expectations.”

Tenneco now offers nearly 800 Monroe OESpectrum units, providing coverage of more than 92 percent of leading Asian and European vehicle applications. The company will expand coverage with dozens of new SKUs in early 2012. Tenneco’s engineers are also targeting industry-first coverage of a number of 2011 and 2012 foreign nameplate applications.

“OESpectrum is designed to be a single-source solution for shops that want to build their foreign nameplate business,” Dennie said. “Our investment in leadership coverage of European and Asian applications is key to the success of this exciting line, and we are committed to consistently being first to market across multiple nameplates.”

The Twin Technology Active Control system within each Monroe OESpectrum unit comprises Tenneco’s latest track-tested 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.

“Our engineers have essentially doubled the number of tuning points in each shock or strut, which allows us to deliver an excellent blend of comfort and control for each application,” he explained.
