Rancho RS5000X 2.5-4″ Lift Shocks for 1981-1986 Chevy K10 4WD

Part Number: RS55001 / RS55112

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to enhance the handling and ride quality of your lifted Chevy K10. Designed for vehicles with 2.5 to 4 inches of lift, these twin-tube gas-pressurized shocks provide a smooth street ride while maintaining the rugged durability required for off-road environments. The oversized shock body allows for increased fluid capacity, ensuring consistent performance by reducing internal heat buildup during heavy-duty use.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping stages to ensure a smooth ride over small bumps while maintaining control during hard impacts.
• Gas Pressurized Twin-Tube Design: High-velocity nitrogen gas charging provides reduced aeration and foaming to ensure consistent damping performance in varied terrain.
• Oversized Shock Body: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and fade-free performance.
• Nitro-Carburized Piston Rod: Heavy-duty reinforced construction provides superior resistance to scuffs and corrosion to ensure a long service life for the internal seals.
