    The Original Load Levelers

    The Hellwig Load Pro Series LP-25 and LP-35 Helper Spring Kits set the standard for all other aftermarket helper springs and are the true workhorse of the Hellwig Spring line. Manufactured with heat treated ASTM 5160 alloy spring steel these units increase your vehicles level load carrying capacity up to the manufacturer's GVWR (Gross Vehicle Weight Rating). Always operate your vehicle safely and never exceed the recommended GVWR, even when using helper springs. They feature a simple "Set it and forget it " bolt-on design using common hand tools, providing both ease of installation and hassle free use. .

    The Hellwig Load Pro Series Helper Spring Kits are available in both Progressive Spring Rate and Constant Spring Rate designs. The Progressive Rate design requires the truck to be loaded and it's spring compressed to activate the helper spring, therefore as the vehicles load increases the helper spring progressively increases its resistance to the load. The Constant Rate design allows the helper spring to immediately react to the vehicles load, therefore compressing very little as load is applied to the vehicle.

    Designed to be installed on full size pick-up trucks and vans, the Hellwig Load Pro Series LP-25 and LP-35 Helper Spring Kits require mounting hardware to accommodate 2 1/2" or 3" wide leaf springs. When ordering be sure to measure the width of your leaf springs and identify the Load Pro Spring kit to determine the appropriate mounting hardware kit to complete the installation.

    LP-25 Features:
  • Heavy Loads - 3-Leaf Stack
  • 2500 lbs. Level Load Capacity
  • Available in Progressive or Constant Rate
  • Design can handle the load 24/7
  • Mounting kit sold separately

    LP-35 Features:
  • Heaviest Loads - 4-Leaf and Up Stack
  • 3500 lbs. Level Load Capacity
  • Available in Progressive or Constant Rate
  • Offers the Maximum in Carrying Capacity
  • Recommended for 3/4 Ton and 1 Ton Applications
  • Mounting kit sold separately
