Rancho RS9000XL 2.5-4″ Rear Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS999190

Summary: The Rancho RS9000XL series delivers industry-leading versatility for the GMC K1500 and Yukon, featuring a manually adjustable 9-position tuning knob. This Tier 2 adjustable system allows drivers to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered specifically for vehicles with 2.5 to 4 inches of rear lift, these shocks provide the precise damping control required to manage increased ride heights and larger tire masses.

Features

• MyRide 9-Position Tuning: A manual adjustment knob provides nine levels of damping control to ensure the perfect ride quality for daily driving or heavy-duty hauling.
• Large Diameter Body: A 2.75-inch heavy-duty reserve tube provides increased oil capacity to ensure cooler operating temperatures during aggressive off-road use.
• Nitrogen Gas Pressurization: High-pressure gas charging provides a barrier against oil foaming to ensure consistent damping performance and rapid response times.
• Polyurethane Bushings: High-performance polyurethane material provides enhanced durability and reduced deflection to ensure precise axle control.
