Part Number: RS999273

Summary: The Rancho RS90000XL series provides industry-leading versatility for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow Ford F-450 owners to instantly adjust damping levels to compensate for varying payload weights or towing requirements. Whether you are driving an unladen truck on the highway or hauling a maximum GVWR load, this adjustable solution ensures optimal ride control and stability.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during sustained hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides a reduction in aeration and foaming to ensure consistent valving performance in demanding conditions.
• Protective Boot: A heavy-duty poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
