Part Number: RS55119

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressure design to deliver a significant upgrade over factory damping. Engineered for the 1961-1971 Dodge D300 and AM General FJ-8A, these shocks feature a unique Progressive Engagement Valving system that minimizes harshness during initial impacts. This Tier 4 shock provides a durable, dent-resistant outer tube that ensures consistent performance and smooth street comfort for vintage workhorses and utility vehicles.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides reduced harshness during initial travel to ensure a smoother ride over small road imperfections.
• Gas Pressurized Twin-Tube: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure consistent damping performance under heavy loads.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term durability in demanding environments.
• Self-Lubricating Seal: A specialized PTFE-coated seal provides reduced friction and heat buildup to ensure a longer service life for the shock absorber.
