RS5000X Gas Shock, The core of this new and innovative shock from Rancho is the unique and patented rebound valving system and an advanced compression phase of the shock absorber. This proprietary process developed by the ride engineers at Rancho will elevate the overall handling and performance of your vehicle on and off-road.

Each RS5000X shock is gas pressurized to 150 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.

The RS5000X series features a 2-1/4-inch 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 248 degrees Fahrenheit. The Rancho RS5000X series design includes patented progressive rebound and compression discs.

At lower speeds or in the earlier stages of the shocks 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, Ranchos 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.

Bilstein 5100 Series shock absorbers are high gas pressure mono tube shocks designed specifically for lifted pickups, SUVs and jeeps. The shocks feature a 46 mm digressive piston with self-adjusting deflective disc valving.

Due to their larger tires and a heightened stance, lifted vehicles place extra demands on a shock absorbers damping ability. The 5100 monotube design and patented digressive valving is uniquely suited to confront these demands.

On or off-road, loaded or unloaded, Bilstein shocks instantly react to changing road inputs to maintain a stable, controlled, and comfortable ride. Bilstein’s superior monotube high gas pressure design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently.

The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise.

Black MAX twin tube shock absorbers have increased fluid capacity and utilize foam-cell technology. When the shock is working hard and gets hot, the foam-cell insert compresses to compensate for oil expansion which maintains consistent MAX performance throughout the operating temperature range of the shock.

The foam-cell design also eliminates air inside the shock which allows for mounting in any direction. Arc-welded end mounts and select specific valving give this shock absorber MAX value.

BILSTEIN 5100 Series *Lifted Performance* Bilstein 5100 Series Shock Absorbers are high gas pressure monotube shocks designed specifically for lifted pickups, SUVs and Jeeps. The shocks feature a 46 Millimeter digressive piston with self-adjusting deflective disc valving.

Their heat-reducing design includes a metal-impacted aluminum shock body that dissipates heat faster than conventional steel. Inside the Internal Floating Piston (IFP) separates shock oil from a high-pressure nitrogen gas chamber that provides a predicable ride quality capable of handling the roughest road conditions.

Combine these new technologies with a competitive price for a winning combination.
