Summary: The Rancho RS9000XL series delivers industry-leading versatility for truck owners who demand control over their ride quality. Featuring a 9-position manual adjustment knob, these shocks allow you to instantly tune your suspension damping from soft for daily commuting to firm for heavy towing or off-road excursions. Engineered to accommodate vehicles with 2.5 to 4 inches of lift, they provide the necessary travel and damping force to maintain stability on the 1981-1986 Chevy K10 platform.

Features

• 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride for any load or terrain.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased oil capacity to ensure cooler operation and consistent performance under heavy use.
• Nitrogen Gas Charged: High-pressure gas optimization provides a faster response rate to ensure the tires maintain maximum contact with the road surface.
