LOS ANGELES, Tues., Jan. 19, 2010 – The new Rancho® 2009-10 Dodge Ram 1500 4WD suspension system (p/n RS6587B) is precisely engineered for superior fit and finish, plus increased on- and off-road performance capabilities. The new Rancho system is fully compatible with Dodge’s electronic stability control system.

Allowing for the use of a larger wheel and tire package, the new Rancho Dodge Ram 1500 system lifts the front and rear stance of the truck while providing 4-inches of lift. The system accommodates up to 34-1/2-in. tires (315 x 70 x 17).

The system includes a heavy-duty, one-piece Rancho subframe made from high-strength low-alloy steel. The system provides exceptional strength while installing easily and maintaining proper CV and driveshaft angles to minimize vibrations. Another key Rancho component of the system are CNCmachined extended steering knuckles. The system includes all alignment hardware and aligns to OE specifications.

The system maintains the factory location of the rack and pinion, a key design element that ensures proper steering integrity and simplification of installation.

The system is fully compatible with the Rancho RS9000XL™ adjustable shock line (front RS999789; rear RS999369). RS9000XL shocks feature a larger diameter reserve tube to allow for cooler and more consistent performance, even under the most demanding conditions. Constructed with larger-than-normal 18- mm diameter chromed piston rods, the shocks are finished in Liquid Metallic Silver. The shocks can be controlled wirelessly through the Rancho MyRIDE™ Wireless Controller, making it easy to instantly manipulate the shock ride profile.

No drivetrain modifications are required for the installation of this system. Stock wheels can be re-used. Bolt-on tie rod assemblies require no cutting or grinding during installation.

Every Rancho system also includes detailed, full-color product installation instructions. The new system is offered with Rancho’s limited lifetime warranty.

Rancho is manufactured and marketed by Tenneco Inc. (NYSE: TEN) and headquartered in Long Beach, Calif.
