Summary: The Rancho RS9000XL series delivers unmatched versatility for the 1988-1999 GMC K1500 Yukon, featuring a globally recognized 9-position manual tuning knob. This Tier 2 adjustable shock allows drivers to instantly transition from a soft, compliant street ride to a firm, controlled setting for heavy towing or off-road excursions. Engineered to accommodate 5 to 6 inches of rear lift, these shocks provide the necessary travel and damping control to manage increased ride heights without sacrificing ride quality.
