Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1987 GMC V1500 4WD

Part Number: RS55112

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade in ride quality for your lifted GMC V1500. Engineered with a unique progressive engagement valving system, these shocks effectively manage the increased unsprung weight of larger tires while maintaining smooth street manners. These gas-pressurized units are specifically configured for 2.5 to 4 inches of rear lift, ensuring your classic 4WD maintains optimal suspension travel and stability on and off the road.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual increase in damping force to ensure a smooth transition between highway cruising and harsh trail impacts.
• Gas Pressurization: High-pressure nitrogen charging provides a reduction in oil foaming and aeration to ensure consistent performance during sustained suspension cycling.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity and physical dent resistance to ensure the internal piston remains functional in rugged environments.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance and tensile strength to ensure long-term seal integrity.
