Rancho RS5000X 4″ Lift Shocks for 1997-2003 Ford F-150 4WD

Part Number: RS55237

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for lifted Ford trucks. Utilizing a sophisticated twin-tube design with a larger 2.25-inch body, these shocks offer increased oil capacity to maintain cool operating temperatures during demanding use. This set is specifically configured for vehicles with a 4-inch lift, ensuring the piston remains within its optimal stroke range for both daily commuting and off-road exploration.

Features

• Crossed Landscape Valve System: Progressive engagement valving provides custom-tuned damping to ensure smooth street comfort and controlled off-road performance.
• 2.25-inch Heavy-Duty Body: Increased fluid capacity provides lower internal pressure and heat dissipation to ensure consistent performance under load.
• Nitrogen Gas Pressurization: 150 PSI gas charge provides a reduction in aeration and foaming to ensure immediate response and fade resistance.
• Protective Boot: Included black polyvinyl accordion boot provides a shield for the shock rod to ensure long-term seal integrity against debris.
