The Superlift Component Box rear block kit provides blocks and hardware for a 6‑inch lift on 2017–2022 Ford F-250 and F-350 Super Duty 4WD models, designed to pair with standard 4‑link radius arms and preserve mounting locations. The kit adjusts rear ride height while helping retain axle location and suspension function under load, useful for owners fitting a higher lift without overhauling the rear suspension. Founded in 1975, Superlift draws on decades of suspension experience.
