Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC G-3500 and AM General FJ-9 platforms. Featuring a 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to compensate for varying payload weights or towing requirements. This Tier 2 adjustable technology transforms the vehicle’s handling from a comfortable street ride to a firm, controlled setting for heavy-duty applications.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for any load or road condition.
• Large Diameter Body: The increased fluid capacity provides improved heat dissipation to ensure consistent performance during heavy-duty hauling.
• Nitrogen Gas Charged: High-pressure gas optimization provides immediate response to road irregularities to ensure tire-to-road contact is maintained.
• Protective Boot: A durable poly-vinyl accordion boot provides a shield for the shock rod to ensure seal longevity against road debris.
