More Information

This Rough Country 51258 Rough Country 6 inch Radius Arm Coilover Conversion Lift Kit for the Ford F250/F350 is a premium suspension upgrade that will make your truck look and perform great. This kit includes everything you need for a complete transformation. Run up to 37 inch tires while preserving the smooth factory ride quality with this impressive upgrade. Rough Country understands that the key to preserving ride quality is keeping the suspension geometry as close to the factory angles as possible. This 6 inch lift kit features a set of durable radius arms, precision fit to bolt right into the factory mounts for an easier installation and a more factory like angle. These beefy Radius Arms dwarf stock arms, weighing in at 27 pounds each and feature durable clevite rubber bushings for maximum vibration absorption. This kit features top mounted reservoir brackets and coilover mounts constructed from 1/4 inch steel. Utilizing this kit removes factory independent coil shock and coil setup, replacing it with massive 2.5" pistons, nitrogen charged, 8-stage adjustable Rough Country Vertex Coilovers. Vertex Coilovers feature a monotube design with an external reservoir for increased oil capacity and damping sensitivity.

When it comes to investing in a high end kit, you'll be pleased to find that Rough Country's 2.5" piston design is beefier and offers an impressive 56% greater fluid capacity than the average reservoir shock. Estimated install time is anywhere from 6-10 hours with cutting and drilling required.
