Summary: The Rancho RS90000XL series delivers industry-leading versatility for heavy-duty applications. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your damping profile to compensate for varying payloads or terrain. Whether you are towing a heavy trailer or driving unloaded, this system provides the specific ride control needed to maintain stability and comfort on your 4″ lifted GMC Sierra 2500 or Hummer H2.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect balance between street comfort and heavy-duty towing stability.
• Large Shock Body: The 2.75-inch diameter body provides increased fluid capacity to ensure cooler operation and consistent performance during high-load cycles.
• Nitrogen Gas Charged: High-pressure gas charging provides a reduction in aeration and foaming to ensure immediate response and fade-free damping.
• Protective Boot: A durable polyurethane shock boot provides a debris shield for the piston rod to ensure long-term seal integrity in harsh environments.
