Part Number: RS999113

Summary: The Rancho RS90000XL series provides unparalleled ride control for the Plymouth PB-series and AM General FJ-9 platforms. Featuring a globally recognized 9-position manual tuning knob, these shocks allow drivers to instantly adjust damping levels to match specific hauling requirements or road conditions. Whether you are maintaining a vintage fleet or optimizing a classic van, this Tier 2 adjustable solution bridges the gap between highway comfort and heavy-duty stability.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the vehicle is perfectly calibrated for varying load weights.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a reduction in aeration and foaming to ensure consistent performance during spirited driving or heavy utility use.
• Large Shock Body: A heavy-duty 2.75-inch diameter body provides increased fluid capacity to ensure cooler operating temperatures under sustained loads.
• Protective Boot: A durable red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
