Hellwig Contact Helper Springs add two additional leaves to factory contact overload springs for 2024–2025 Ford F250/F350 2WD and 4WD models and broader 2023–2026 F250–F650 applications as noted; they do not fit models with adaptive headlights. These helper leaves engage sooner under load to reduce sag and increase support while preserving normal ride when unloaded. They mount to factory contact pads for straightforward installation and improved load handling.
