Summary: The Rancho RS5000X series provides a significant upgrade for Ford F-150 owners running a 6-inch lift kit. Utilizing an advanced Cross-Tuned twin-tube design, these shocks balance rugged off-road durability with smooth on-road handling. Designed to mitigate harsh impacts and reduce body roll, this complete set ensures your lifted truck remains composed across varying terrain.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide increased control during high-speed transitions to ensure a stable ride on uneven surfaces.
• Twin-Tube Gas Pressure: The 150-PSI nitrogen gas charge provides a consistent damping force to ensure reduced aeration and shock fade during spirited driving.
• Glass-Filled Fluon Piston Seal: A heavy-duty PTFE-based seal provides a tighter fit between the piston and pressure tube to ensure long-term durability and consistent performance.
• Double-Welded Mounts: Reinforced loop-style mounts provide superior structural integrity to ensure the shocks withstand the stresses of a 6-inch lifted suspension geometry.
