Summary: The Rancho RS9000XL series delivers industry-leading versatility for classic Chevy K10 owners who demand control over their ride quality. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly tune your damping levels from soft to firm. Whether you are navigating daily commutes or hauling heavy loads, the RS9000XL provides a customized suspension response to eliminate the “one size fits all” compromise of standard shocks.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping to ensure the driver can transition from street comfort to off-road firmness.
