NEW RANCHO® RS7000MT MONOTUBE STRUTS RELEASED FOR 2007-12 CHEVY & GMC TRUCKS AND SUVS

LONG BEACH, CA, Aug. 7, 2012 – Tenneco Inc.’s Rancho® brand has recently released Rancho RS7000MT™ struts for a series of popular Chevy and GMC trucks and SUVs.

Specifically engineered for 2007-2012 Chevrolet Silverado/Suburban/Tahoe and GMC Avalanche/Sierra/Yukon applications, the RS7000MT struts were developed through Rancho’s unique relationship with original equipment manufacturers as the performance ride control and suspension system brand of Tenneco Inc. (NYSE: TEN).

Rancho RS7000MT struts quickly and effectively dissipate heat, providing exceptional resistance to overheating during extreme use, like hauling or off-road use on rough roads or trails. Each Chevrolet/GMC strut was engineered using advanced valving, precisely tuned to these vehicles. Maximizing damping efficiency and providing control on the trucks and SUVs, the RS7000MT monotube struts help deliver a fast, precise response in both on- and off-road driving.

Each RS7000MT strut includes the spring seat. Re-use of the OE coil spring and mount are required.

The new Rancho RS7000MT strut coverage includes:

• 2007-12 GMC Avalanche 1500 4WD (excludes Electronic Ride Control package) – RS7784, front; RS7274, rear

• 2007-12 Chevrolet Silverado/GMC Sierra 1500 4WD (excludes Electronic Ride Control, Quadrasteer, and 4WD packages) – RS7784, front; RS7198, rear
