Rancho RS9000XL 0″ Lift Shocks for 1975-1991 Ford E-350

Part Number: RS999136 / RS999115

Summary: The Rancho RS9000XL series provides the ultimate in ride control for the Ford E-350, featuring a globally recognized 9-position manual adjustment knob. This Tier 2 adjustable system allows drivers to instantly transition from a soft, compliant street ride to a firm, controlled setting for heavy hauling or towing. Designed specifically for stock height applications, these shocks eliminate the compromise between comfort and utility by putting the tuning power directly in your hands.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the vehicle is perfectly calibrated for varying load weights.
• Large Shock Body: A massive 2.75-inch diameter tube provides increased fluid capacity to ensure consistent performance and reduced fade during high-duty cycles.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure the tires maintain maximum contact with the road surface.
• Polyurethane Bushings: High-durability polyurethane material provides superior pivot articulation to ensure long-term service life and reduced NVH (Noise, Vibration, Harshness).
