Fits select 1994-2025 Dodge and Ram 1500, 2500, and 3500 trucks. The Rancho RS5000X series shock absorber utilizes a patented Progressive Engagement Valving (PEV) system to provide custom-tuned control for both on-road comfort and off-road stability. Built with a large twin-tube body, this shock features Cross Tuned technology that coordinates rebound and compression phases to minimize body roll and improve overall handling.

• Precision Valving: Progressive Engagement Valving reduces initial impact harshness at low speeds while maintaining firm control during aggressive maneuvers.
• Heavy-Duty Construction: Features a 16mm nitro-carburized piston rod for superior scuff and corrosion resistance, paired with a 35mm sintered iron piston.
• All-Weather Performance: Nitrogen gas pressurized to 150 PSI minimizes air-to-oil foaming, while all-weather fluid ensures consistent damping from -40 to 248°F.
• Durability: Equipped with double-welded loops at high-stress points, a fluon-banded piston for consistent sealing, and a polyvinyl protective boot.
• Technical Specs: MPN RS55197; Twin-tube design; 16mm rod diameter; 35mm piston diameter; Includes polyurethane rebound bumper and rubber bushings.

Fits select 1994-2002 Dodge Ram 1500, 2500, and 3500 pickups (5.9L).

The Rancho RS5000X (MPN: RS55195) is an advanced twin-tube shock absorber designed to bridge the gap between highway comfort and off-road control. Engineered with Cross Tuned technology and a unique Progressive Engagement Valving system, this shock provides custom-tuned damping that reduces initial impact at low speeds while maintaining firm control during aggressive maneuvers. The larger twin-tube body is pressurized with 150 PSI of nitrogen gas to minimize the air-to-oil mixture, effectively preventing performance fade and foaming under heavy workloads.

Built for long-term durability in harsh environments, the RS55195 features a 16mm nitro-carburized piston rod for superior scuff and corrosion resistance. The unit is equipped with double-welded loops at high-stress points and a 35mm sintered iron piston to ensure structural integrity. A polyurethane rebound bumper and rubber bushings help isolate road vibrations, while the included polyvinyl boot protects the rod and seal from debris.

• Gas-pressurized to 150 PSI to minimize aeration and shock fade
• 16mm nitro-carburized piston rod resists scuffs and corrosion
• 35mm sintered iron piston for enhanced structural integrity
• Large twin-tube body with all-weather fluid rated for -40 to 248°F
• Cross Tuned technology with exclusive rebound and compression valving
• Polyurethane rebound bumper for smoother impact absorption
• Includes protective polyvinyl boot
• Manufacturer Part Number: RS55195

Fits 1993-1998 Jeep Grand Cherokee (Base, Laredo, Limited, SE, TSi, Orvis, and 5.9 Limited).

The Rancho RS5000X series (MPN: RS55194) is a twin-tube gas-pressurized shock designed to improve handling and control on and off-road. Engineered with Cross Tuned technology, these shocks utilize a unique rebound valving system and an advanced compression phase to manage impacts across various terrains. The nitrogen gas charge is pressurized to 150 PSI to minimize aeration and foaming, ensuring consistent damping performance even during heavy use.

• 35mm sintered iron piston provides structural integrity and increased surface area for precise control.
• 16mm nitro-carburized piston rod resists scuffs and corrosion for long-term durability.
• All-weather fluid allows for consistent operation in extreme temperatures ranging from -40 to 248°F.
• Progressive Engagement Valving reduces initial impact harshness at low speeds.
• Self-lubricating seal and fluon-banded piston enhance responsiveness and reduce internal friction.
• Includes a polyvinyl protective boot and rubber bushings to absorb ride harshness.
• Double-welded loops at stress areas for maximum strength.

Fits select 1988-2005 Chevrolet and GMC trucks and SUVs, including Blazer, Jimmy, Tahoe, and C/K-Series 1500/2500/3500 pickups.

The Rancho RS5000X series redefines twin-tube shock performance with its patented Progressive Engagement Valving (PEV). This application-specific system is custom-tuned to minimize initial impact at low speeds while maintaining firm control during high-speed compression. Built to withstand extreme environments, the twin-tube body is nitrogen-charged to 150 PSI, significantly reducing fluid foaming and damping fade during heavy-duty use or off-road excursions.

Engineered for durability, this shock features a 16mm nitro-carburized piston rod to resist corrosion and double-welded loops at high-stress mounting points. The large 35mm sintered iron piston increases the surface area for fluid control, ensuring smoother rebound and compression cycles even when temperatures range from -40 to 248°F.

• Gas-pressurized to 150 PSI to minimize aeration and shock fade
• 16mm nitro-carburized piston rod for enhanced structural integrity
• 35mm sintered iron piston delivers heightened motion control
• Cross-tuned technology for optimized handling on and off-road
• Polyurethane rebound bumper and rubber bushings for vibration isolation
• Includes polyvinyl protective boot to shield the rod and oil seal
• Operating temperature range: -40°F to 248°F
