Maximize the load-carrying capacity of the rear suspension in your GM Silverado/Sierra 2500HD 2WD/4WD or Sprinter 2500/3500 Van with the Hellwig 2551 LP-25 Load Pro Helper Springs. Hellwig's Helper Springs set the standard for all other aftermarket helper springs. Featuring Progressive Spring Rate and Fulltime 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 Fulltime design the Hellwig Spring immediately reacts to the vehicles load, therefore compressing very little as load is applied to the vehicle.

Set it and forget it. LP 25 is rated at 2500lbs level load carrying capacity, not exceed the vehicles Gross Vehicle Weight Rating. Installation kit required (not included).
