Part Number: RS999001

Summary: The Rancho RS9000XL series provides industry-leading adjustability for drivers who demand total control over their suspension damping. Featuring a 9-position manual tuning knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or aggressive off-road use. Engineered for vehicles with 2.5 to 4 inches of lift, this set ensures your classic K5 Blazer or Jimmy maintains optimal tire contact and stability across varying terrains.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure custom ride control for any load or road condition.
• Nitrogen Gas Pressurized: High-pressure gas charging provides a faster response rate and reduced aeration to ensure consistent performance during rapid suspension cycling.
• Large Shock Body: An oversized 2.75-inch diameter body provides increased fluid capacity to ensure lower operating temperatures during heavy-duty use.
• Polyurethane Bushings: High-density polyurethane material provides improved durability over rubber to ensure a more precise steering response and reduced deflection.
