Rancho Shock Absorber (MPN: RS55100)

Advanced shock technology for improved vehicle handling and performance.

The Rancho Shock Absorber features innovative Dynamic Rebound Spring technology, which enhances control and reduces body roll during driving. This shock absorber is designed with a patented rebound valving system that optimizes performance both on and off-road. The enlarged twin tube body increases fluid capacity, allowing for cooler operation and improved vehicle control across various terrains and speeds.

With gas pressurization at 150 PSI, this shock absorber provides a mild boost in spring rate, contributing to overall vehicle stability. The 16 millimeter nitro carburized rod enhances durability by offering increased resistance to scuffing and corrosion. Additionally, the polyurethane rebound bumper effectively manages rebound motion under harsh driving conditions, ensuring a smoother ride.

The Rancho Shock Absorber is equipped with low friction, self-lubricating seals that protect against dirt and debris, further extending the lifespan of the product. Black natural rubber bushings are included to absorb ride harshness and minimize road noise and suspension vibration, making this shock absorber a reliable choice for vehicle-specific applications.

Features

• Progressive Engagement Valving: 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
• Dynamic Rebound Spring (DRS) Technology: New DRS Technology Is A Unique Internal System
• Tuned Compression Control Valve: Precision Tuned Shim Stacked Valving Allows The Motion Of The Shock To Work In Harmony With The Vehicle During On And Off Road Driving
• Enlarged Twin Tube 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
• Gas Pressurization Of Shock: Each Shock Absorbed Is Gas Pressurized To 150 PSI; Gas Pressurization Also Provides A Mild Boost Of Spring Rate To The Vehicle
• 16 Millimeter Nitro Carburized Rod: From Increased Scuffing Resistance To Additional Protection Against Corrosion, The Process Enhances The Shock’s Overall Durability
• Rebound Bumper: Polyurethane Bumper That Helps Control The Rebound Motion During Harsh Driving Conditions
• Black, Natural Rubber Bushings: Provides Additional Ride Harshness Absorption And Reduce Transmitted Road Noise And Suspension Vibration
• Low Friction, Self Lubricating Seal: This Seals Provides An Extra Layer Of Defense Against Dirt And Debris
