RS5000 ™X SHOCK ABSORBER
Inside the new, innovative Rancho® RS5000™X shock is a unique, patented valving system and advanced compression functionality.
Developed by the engineers at Rancho, The Rancho RS5000X Cross-Tuned Technology will improve the vehicle’s overall on- and off-
road handling and performance.
PROGRESSIVE ENGAGEMENT VALVING:
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.
