Rancho RS55034

The Rancho RS5000X Series design includes patented progressive rebound and compression discs. At lower speeds or in the earlier stages of the Shock’s travel, an eccentric disc in the valve shim stacks will engage the valving at lower frequencies, helping to control the energy of motion as the cycle of the Shock increases or decreases in its action. When hitting a pothole, off-road trail obstacle or similar activity, Rancho’s Progressive Engagement Valving allows for early flow of fluid, helping to reduce harsh initial impacts and to control the flow of fluid in a progressive, gradual manner through the valving. During on- or off-road driving activities like washboard roads or when traveling a rough fire road, the early flow of fluid helps to minimize a “rough” ride as the piston movement is able to glide through the initial travel motion of the Shock with minimal ground impact or force. If needed, the Progressive Engagement Valving will further engage to maintain control and stability.
