Summary: The Rancho RS900XL series provides industry-leading adjustability for classic Jeep and utility applications. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly transition from soft street cruising to firm control for off-road or work use. Engineered for the rear of 1941-1963 Jeep MB and M38 models, they offer a custom-tuned ride quality that modernizes the handling of vintage 4WD platforms.

Features

• 9-Position Tuning Knob: A manual adjustment dial provides 400% change in damping force to ensure the driver can fine-tune the ride for specific loads or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during sustained use.
• Nitrogen Gas Charged: High-pressure gas displacement provides immediate response to road irregularities to ensure consistent tire-to-ground contact.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
