Description

The Rough Country 6-inch 4-Link Coilover Conversion Lift Kit (MPN 50856) is designed to significantly upgrade the ride quality and stance of fourth-generation Ford Super Duty trucks. This comprehensive suspension system replaces factory arms with a 4-Link setup, featuring durable, fixed upper arms and adjustable lower control arms. It includes radius arm drop brackets to maintain proper geometry and caster settings for factory-like handling. The kit's core innovation is the conversion from independent coil shock and coil setup to massive 2.5-inch piston, nitrogen-charged, 8-stage adjustable Vertex Coilovers. These coilovers boast a monotube design with an external reservoir for increased oil capacity and damping sensitivity, offering 56% greater fluid capacity than average reservoir shocks. This kit also comes with V2 Monotube shocks for the rear.
