The Hellwig LP-35 Helper Spring set is a high-performance aftermarket suspension component designed to enhance load-carrying capacity for heavy-duty trucks. Built with a Fulltime Spring Rate design, this helper spring is considered the workhorse of the Hellwig Spring line, providing consistent support for vehicles that regularly carry heavy loads. It is ideal for fleet applications or vehicles subjected to daily heavy-duty use, offering improved stability and load management. Constructed to meet demanding performance standards, the LP-35 delivers durability and reliable support, ensuring vehicle stability under load and reducing sagging or uneven ride height.
This product is specifically designed for 2001-2007 Ford F-350 Super Duty trucks. Compatibility depends on vehicle configuration, especially if factory contact overload springs are present—users should verify fitment for their specific year and model. The helper spring kit is a bolt-on upgrade that requires the purchase of a separate LP mounting kit for installation. It is intended for vehicles that frequently carry heavy loads or tow, providing enhanced load support and ride quality. The kit does not include mounting hardware, which must be purchased separately, and is suitable for use in fleet, towing, or heavy-duty applications.
