Rancho RS9000XL 2.5-4″ Lift Shocks for 1969-1986 Chevy K-20 4WD

Part Number: RS999001

Summary: The Rancho RS9000XL series is the industry leader in adjustable damping, providing a custom-tailored ride for your classic Chevy K-20. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or aggressive off-road use. Engineered for vehicles with 2.5 to 4 inches of lift, this set provides the necessary travel and damping control to manage the increased center of gravity on lifted 4WD applications.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the perfect ride quality for any terrain or load requirement.
• Large Shock Body: The 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent performance during heavy-duty cycles.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade-free control.
• Polyurethane Bushings: High-durability polyurethane material provides superior pivot articulation to ensure reduced NVH (Noise, Vibration, and Harshness).
