Part Number: RS999055

Summary: The Rancho RS90000XL series provides industry-leading versatility for heavy-duty applications, featuring a 9-position manual tuning knob that allows drivers to adjust damping levels on the fly. Designed for vehicles with 5-6 inches of lift, these shocks solve the compromise between highway comfort and off-road stability by providing a customizable ride profile. Whether you are towing heavy loads or navigating technical trails, these shocks allow you to dial in the exact firmness required for your specific terrain.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can switch between soft street comfort and firm off-road control.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operation and reduced fade during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides consistent valving response to ensure the shock maintains performance during rapid cycling.
