Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1987-1991 GMC V3500 4WD

Part Number: RS55134

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your GMC V3500. Engineered specifically for vehicles with 2.5 to 4 inches of rear lift, these shocks feature a unique progressive engagement valving system that minimizes harshness during initial impacts. By balancing internal pressure and oil flow, the RS5000X provides the durability needed for off-road environments while maintaining smooth street comfort for daily driving.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between damping forces to ensure consistent control on uneven terrain.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure fade-free performance during sustained cycling.
• Large Shock Body: A 2.25-inch reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty hauling or towing.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity.
