Product Details

Rancho's new RS9000XL shock absorbers feature adjustable damping with either a 2.75- or 2.38-in. diameter reserve tube. This massive shock body allows the RS9000XL to run cooler and more consistent even under the most demanding towing conditions, enhancing performance and durability, and is constructed with a larger than typical 18-mm diameter chromed piston rod. Rancho RS9000XL shock series are engineered with nine position tuning technology that provides nine different levels of shock performance, allowing adjustment from very soft to very firm. These premium shocks also have polyurethane bushings that enhance shock performance.
