Vehicle-Specific Tuning & Advanced Engineering Drive Every Rancho® Shock Absorber

More than 60 Years in Industry, Global OE Presence, Involvement in Grassroots and Performance Events Evident in Product Features
Long Beach, Calif., November 15, 2016 – Master the terrain. Rancho® shock absorbers – including the renowned RS9000™XL, RS7000®MT, RS5000™X shock absorbers – have helped performance enthusiasts drive and conquer even the harshest, most obscure environments around the globe. Through over 60 years of innovation, application-specific technology and engineering leadership, the Rancho brand continues to drive the industry standard for shock development and ride control technologies specific to each vehicle.
“The Rancho brand has a unique market position – our products are developed and sold on a global scale with a rich heritage of OE relationships and research and design at a grassroots level,” said Chris Gauss, director, performance products, Tenneco. “As we continue to launch new RS9000XL, RS7000MT and RS5000X applications, we’re continuing our commitment to developing application-specific products and designs that are completely ride tested and validated before entering the marketplace.”

Globally recognized as the first nine-position, manually adjustable ride control series in the off-road market, the Rancho RS9000XL shock series delivers nine different levels of performance to on- and off-road trucks, SUVs and Jeeps. The RS9000XL application-specific shock design counteracts the extra unsprung mass inherent in larger tire and wheel combinations. This series also is ideal for towing applications and more. In 2014, Overland Journal awarded the Rancho RS9000XL its “Editor’s Choice” award.*
Rancho RS7000MT monotube shocks feature high controls for reduced roll and sway and are extremely resilient and highly effective in the dissipation of heat, providing truck, SUV and Jeep owners with a shock absorber ideal for extreme off-road use and larger wheel and tire packages. Each RS7000MT shock includes application-specific deflective disc valving that automatically senses and responds to any suspension input or change in terrain to provide more control and a more precisely matched ride. Due to relationships with OEMs, RS7000MT series units feature advanced 10-stage velocity sensing valving that is precisely tuned to each application.

Manufactured in North America and Australia, Rancho application-specific RS5000X series shocks feature X-Cross Tuned Technology to provide significantly improved on- and off-road performance. The shocks also include Progressive Engagement Valving, a patented design that utilizes progressive rebound and compression discs, helping to control harsh impacts and helping to better control fluid movement for a more-precise ride profile. Each RS5000X series shock is application engineered.
The Rancho brand carries an industry leading Performance Guarantee and 90-day risk-free ride offer that lets enthusiasts try RS9000XL, RS7000MT or Rancho RS5000X shocks for any truck or SUV for 90 days. Consumers can return their shocks within 90 days for a full refund of the product’s purchase price. For a complete list of applications covered by the warranty, please visit
