Developed by our Engineers in Adelaide, and manufactured by Monroe Australia, the Australian Made Rancho RS5000X series of shocks and struts offer a robust twin-tube construction and application specific tuning for improved load carrying and towing performance without a harsh ride.

Rancho® RS5000™X

Made in Australia for Australia

Upgrade your shocks with RS5000™X Shocks and Struts

Innovative Rancho® RS5000™X

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® RS5000™X Cross-Tuned Technology will improve the vehicle’s overall on- and off-road handling and performance.

Progressive Engagement Valving

The Rancho RS5000™X series design includes patented progressive rebound and compression discs. At lower speeds or in the earlier stages of the shock’s travel, a low speed tuning 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.

5000X features and benefits

Rancho RS5000X series shocks and struts have a robust twin-tube construction. Unlike monotubes, twin-tubes can withstand significant stone / rock impact damage to the shock body and still operate correctly through their full range of motion. This makes them the ideal choice for rough roads or the Australian Outback.

Rancho RS5000X series shocks and struts are available in Variable Load and Constant Load versions so you can choose the right shock for the way you use your 4×4.

Variable Load Part Numbers have been tuned for “all round” use. Tuned with a rear axle load of 250kg they provide improved load carrying and towing performance vs OE shocks, but maintain a smooth ride when the vehicle is not loaded. The 250kg tune makes them the ideal choice for common levels of accessories such as a canopy, towbar and draw system.

Constant Load Part Numbers have been tuned for high permanent accessory loads such as tool storage cabinets, trade equipment and slide on campers. Tuned with the vehicle at its maximum GVM, they provide optimal load carrying and towing performance but are not recommended for use on vehicles that are not loaded due to harsh ride under no load.

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 washboarding or when travelling 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.


The Tuned Compression Control Valve is a custom-tuned, clamped disc base valve that regulates fluid transfer during the shock’s compression cycle to help absorb impacts without disc flutter and to help maintain vehicle control in virtually any environment. The precision-tuned shim stacked valving allows the motion of the shock to work in harmony with the vehicle during on- and off-road driving.

The RS5000X series features a 54.0mm diameter shock body. A larger shock body allows for increased fluid capacity to operate cooler and to increase vehicle control and performance at varying speeds and terrains. The RS5000X series combines a larger shock body with all-weather fluid, allowing the shock to withstand internal temperatures between -40 and 120 degrees Celcius.

Each RS5000X shock is gas pressurized to 60 PSI.* The twin tube, gas pressurized shock has a variety of advantages including minimizing air-to-oil mixture that can cause foaming and shock fade. Gas pressurization also provides a mild boost of spring rate to the vehicle.

Every Rancho RS5000X shock piston rod is strengthened through induction hardening and hard chrome plating. These processes enhance the shock absorber’s strength and overall durability.

The RS5000X’s 35 mm bore helps to provide heightened control of shock motion due largely to the expanded piston area. The 35mm bore also acts to extend shock life by reducing internal pressures on the seal & reducing the rate of wear of the piston band.

The sintering process forms objects from powders using atomic diffusion. The powdered material is heated to just below its melting point, fusing all of the particles together to create the piston. This process brings increased structural conformity to each Rancho RS5000X piston.

 

Each RS5000X series IFS strut has a high-strength, polyurethane bumper that helps control the rebound motion during harsh driving conditions. The rebound bumper greatly reduces wear and tear during on- and off-road driving. When your shock rebounds from an obstacle at an excessive rate, the polyurethane bumper dampens the piston rod cycle at its peak point of travel.

The bushings used on the Rancho RS5000X series shocks provide additional ride harshness absorption and reduce transmitted road noise and suspension vibration to result in a smoother ride and longer life for shocks and related suspension components.

 

The low-friction, self-lubricating seal included in the RS5000X shock retains gas and oil to help prolong performance and allow for quicker rebound and smoother compression during the shock cycle. This seals provides an extra layer of defense against dirt and debris.

 

Each Rancho RS5000X series shock includes a red polyvinyl accordion protection boot, adding protection to the shock rod and oil seal during on- and off-road driving.

 

The RS5000X composite piston band provides smoother piston travel and greater responsiveness to changing road conditions. Each glass-filled band offers incredibly smooth operation within the shock absorber cylinder due to Fluon, a slippery glass and plastic material.

Rancho engineers place extra emphasis on welded construction at stress areas – like mounting points – of the RS5000X shock. Each shock includes double-welded loops for added strength and durability.
