LP 25 and LP 35 Series

This Hellwig Helper Spring 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.

Manufactured with heat treated ASTM 5160 alloy spring steel these units increase your vehicles

level load carrying capacity up to the manufacturer’s Gross Vehicle Weight Rating

. Designed to

install on full size pick-up trucks and vans, this unit requires mounting hardware to install

properly on a 2 1/2 " wide spring 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”. The LP 25 is rated at 2500lbs level load carrying capacity

and the LP 35 is rated at 3500lbs level load carrying capacity, not exceed the vehicles GVWR

Trac-Bars

The perfect compliment to a Hellwig Motorhome Sway Bar, this unit controls lateral movement

of the vehicles leaf springs. By aligning and maintaining the axle laterally under the frame your

motorhome will track better with less wandering and rut chasing. These units provide reduced

driver fatigue, less driver corrections, increased vehicle control and improved driving

confidence. Bolt-on design allow for installation with common hand tools. Kits include all the

components necessary to complete you installation including powder coated brackets, zinc plated

hardware and installation instructions.

Gross Vehicle Weight Rating, GVWR. The rating assigned to a vehicle stating the maximum allowable load for that

vehicle. For example a vehicle with a 6500lb GVWR limits the maximum load of the vehicle and its payload to

6500lbs.

Hellwig works hard to design kits that bolt directly to your vehicle. In some instances and for maximum

effectiveness of your installation drilling may be required.
