The Superlift Component Box supplies parts for a 4‑inch lift on 2011–2016 Ford F-250 and F-350 Super Duty 4WD trucks, supporting replacement radius arms or a 4‑link conversion. Designed for diesel-equipped Super Duties, the box helps reestablish proper suspension mounting and geometry after a modest lift to improve ground clearance without compromising everyday drivability. Founded in 1975, Superlift draws on decades of suspension experience.
