Rancho RS5000X 0-2″ Lift Shocks for 1977-1986 Chevy K-30 4WD

Part Number: RS55151

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your Chevy K-30. Featuring a cross-tuned twin-tube design, these shocks utilize a unique progressive engagement valving system to minimize harshness during initial impacts. Designed for vehicles with 0-2 inches of lift, they provide the ideal balance of off-road ruggedness and smooth street manners for classic 4WD applications.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between damping stages to ensure controlled handling on uneven terrain.
• Gas Pressurized Twin-Tube: Nitrogen gas charging reduces aeration and foaming provides consistent damping performance to ensure reliable operation under heavy loads.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity and corrosion resistance to ensure a long service life in harsh environments.
• Large 2.25-inch Body: An increased fluid capacity provides better heat dissipation to ensure consistent performance during extended off-road use.
