Description

The Rough Country 6-inch Radius Arm Coilover Conversion Suspension Lift Kit (MPN: 53958) is a comprehensive upgrade designed for 2008-2010 Ford F-250 and F-350 Super Duty 4WD gas models. This kit provides 6 inches of lift, allowing for the use of up to 37-inch tires while aiming to preserve the factory ride quality. Key components include ultra-durable Radius Arms, which are significantly beefier than stock (27 lbs each) and feature Clevite Rubber Bushings for maximum vibration absorption, ensuring proper suspension geometry by bolting directly into factory mounts. The kit also converts the factory independent coil shock and coil setup to an advanced 2.5-inch piston, nitrogen-charged, 8-stage adjustable Vertex Coilover system. These Vertex Coilovers boast a monotube design with an external reservoir, providing increased oil capacity and damping sensitivity, and offering 56% greater fluid capacity than average reservoir shocks. Additional features include an adjustable alignment cam for caster adjustment at the axle and fabricated rear blocks, which are stronger and more durable than traditional cast blocks. The installation requires cutting and drilling, with an estimated timeframe of 6-10 hours.
