Engineers Combine Classic Rancho RS5000^™ Shock Design with New Features for Added Performance, Global Appeal

Las Vegas, Nov. 4, 2014 – The Rancho^® brand has released a new larger RS5000X™ shock series that helps deliver precisely controlled off-road performance to lifted trucks and sport utility vehicles found around the globe. The new RS5000X shock series includes Cross-Tuned Technology, a new, unique valve design that allows for increased control and consistent ride profile with a larger shock body.

This latest shock innovation from Rancho will be on display at the Rancho booth (Central Hall, No. 25133) during the 2014 Specialty Equipment Market Association (SEMA) Show, Las Vegas. Booth visitors will be able to experience the Rancho RS5000X™ Tech Chamber, an interactive, media-rich educational experience that highlights the new shocks.

“The Rancho RS5000X series gives vehicles found in North America – and around the world – another great choice for a performance shock,” said Chris Gauss, Director, performance brands, Tenneco. “By introducing a patented valve technology, enlarging the shock body and adding other key features that enhance the original design, enthusiasts will see more consistent performance and extended capabilities in a wide-variety of environments and regions.”

The new Rancho RS5000X shock series has a large 2.25-inch diameter reserve tube that delivers greater oil capacity and can enhance overall performance. The larger body diameter allows the RS5000X shock to run cooler and more consistent in more extreme conditions and varying vehicle speeds while extending shock durability.

Each new RS5000X shock also includes a solid, 16mm nitro-carb rod to offer strength and durability during off-road driving. The RS5000X shock is gas pressurized to add a mild boost of spring rate to potentially minimize foaming and shock fade. The series also features a glass-filled fluon banded piston that provides smoother piston travel and greater responsiveness when road conditions vary.

Each RS5000X shock is finished in classic Rancho bright white paint with a full-color Rancho RS5000X decal and each shock includes a protective Rancho red boot.

The Rancho brand first launched the original RS5000^™ shock series in 1985 and it has grown to be one of the best-selling, high-performance shock absorbers in the world. A leader in performance suspension systems and shock absorbers, Rancho performance suspension and shocks are manufactured and marketed by Tenneco.
