The Superlift Component Box supplies lower link arms and hardware for a 4–6 inch lift on 2005–2022 Ford F-250 and F-350 Super Duty 4WD applications, supporting a 4-link conversion on diesel-equipped trucks to restore correct suspension geometry after a moderate lift. Use it to complete or upgrade an existing Superlift lift system. Founded in 1975, Superlift draws on decades of suspension experience.
