LOS ANGELES, Wed., Jan. 26, 2011 – Rancho® – an engineering leader in the off-road suspension marketplace – has announced the release of a new, highly engineered Rancho RS7000MT™ monotube shock series. Rancho products are manufactured and marketed by Tenneco Inc. (NYSE: TEN) and headquartered in Long Beach, Calif.

“Our Rancho monotube shocks offer a way to get rid of heat more easily inside the shock absorber, making you less susceptible to failure or overheating on the road or trails,” said Joe Pase, general manager, Rancho.

The new Rancho monotube shock absorbers – available this May at performance retailers in North America – offer exceptional response to overheating on rough roads or trails. The new shocks help deliver fast, precise response required by many late-model vehicles.

Built to the exacting standards of Rancho engineers, the new shocks feature a high-pressure gas charge separated from the internal oil to provide maximized damping efficiency and control on vehicles that utilize monotube technology.

Engineered to the highest tolerances and including the strongest seals to mantain oil integrity and performance, the new Rancho RS7000MT shocks – which provide more efficient heat dissipation for less fade – offer precise control through a 46mm bore and piston. The 14mm piston rod is chrome for added strength and durability.

Rancho also finishes every RS7000MT shock by brushing and zinc plating then clear coating the shock body, providing an extra long-life. Rancho also includes a black protective boot to protect the piston rod. All Rancho RS7000MT shocks include all detailed and illustrated installation instructions inside the product box.
