Hellwig 11-21 Ford F-250 Load Pro- Up To 3500lb Level LC 4 Leaf Stack Helper Spring w/o Mounting Kit

The Hellwig LP-35 Helper Spring is a high-performance aftermarket suspension component designed for heavy-duty applications. Built with a Fulltime Spring Rate design, it serves as a reliable workhorse for vehicles that regularly carry substantial loads, such as fleet vehicles or trucks used for heavy hauling. Constructed to meet demanding standards, this helper spring enhances load-carrying capacity and stability, ensuring consistent performance under heavy weight conditions. Its robust design improves vehicle handling, reduces sag, and maintains level ride height, making it an essential upgrade for vehicles subjected to frequent heavy loads.

This helper spring is compatible with 2011–2021 Ford F-250 models and is intended for vehicles equipped with leaf spring suspension systems. It is suitable for use in fleet, towing, or heavy-duty daily driving scenarios where load support is critical. Installation requires the purchase of a separate LP mounting kit, especially if the vehicle is equipped with factory overload springs. This product does not include mounting hardware and is designed as a bolt-on upgrade to improve load capacity and ride quality for heavy-duty Ford F-250 trucks.
