Rancho RS9000XL 0″ Front Lift Shocks for 2011-2022 Chevy Silverado/Sierra 3500HD Chassis Cab

Part Number: RS999377

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping control, specifically engineered for heavy-duty applications. Featuring a 9-position manual tuning knob, these shocks allow owners of the Chevy Silverado and GMC Sierra 3500HD Chassis Cab to instantly transition from a soft street ride to a firm setting for heavy hauling or towing. This versatility solves the common issue of “one-size-fits-all” damping, ensuring your truck remains composed regardless of payload or terrain.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping resistance to ensure the vehicle is perfectly calibrated for daily driving, towing, or off-road use.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure consistent cooling and reduced fade during extreme heavy-duty cycles.
• Nitro-Carburized Rod: The heavy-duty 18mm piston rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity in harsh environments.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability and responsiveness to ensure a more controlled steering feel compared to standard rubber.
