Rancho RS9000XL 4″ Rear Lift Shocks for 2004-2008 Ford F-150 4WD

Part Number: RS994287

Summary: The Rancho RS9000XL series delivers industry-leading versatility for drivers who demand total control over their suspension damping. Featuring a globally recognized 9-position manual adjustment knob, these shocks allow you to instantly transition from a soft street ride to a firm setting optimized for heavy towing or off-road stability. Engineered for vehicles with a 4-inch rear lift, the RS994287 provides the necessary travel and damping capacity to maintain tire contact and ride quality on the Ford F-150 and Lincoln Mark LT platforms.

Features

• 9-Position Tuning Knob: A manual external adjustment dial provides nine distinct levels of damping force to ensure the perfect ride for daily driving, towing, or hauling.
• Large Shock Body: A 2.75-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitrogen Gas Charged: High-pressure gas charging provides a rapid response time to road imperfections to ensure consistent performance and reduced aeration.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.
