Hellwig 3551 LP-35 Load Pro Helper Springs

The Hellwig 3551 LP-35 Load Pro Helper Springs will improve the stability of your truck or van when hauling. The Hellwig Helper Spring set the standard for all other aftermarket helper springs. Featuring Progressive Spring Rate and full time Spring Rate design, this spring is the workhorse of the Hellwig Spring line. With the Progressive design the vehicle must be loaded and its spring compressed to activate the Hellwig Spring, therefore as the vehicles load increases the Hellwig Helper Spring progressively increases its resistance to the load. In the full time design the Hellwig Spring immediately reacts to the vehicles load, therefore compressing very little as load is applied to the vehicle.

Designed to install on full size pick-up trucks and vans, this unit requires mounting hardware to accommodate 2 1/2 or 3 wide leaf springs. When ordering be sure to identify the spring kit and the appropriate mounting hardware kit to complete the installation. Simple bolt on design using common hand tools provide the installer ease of installation and the vehicle owner hassle free use. Set it and forget it.
