Mount Under Factory Axle U-Bolt Plates. Variable Rate Leaves Do Not Effect Ride When Unloaded. Adds New Life To Old Springs. High Quality Spring Steel Leaves.
Hellwig's medium-duty EZ-990 Helper Springs pack a lot of capability in every box. Packaged complete with the same heavy duty powder coated and plated components, hardware and installation instructions as our heavy duty helper spring products, these kits are designed for the vehicles that need lighter assistance in carrying a load. Simple bolt on design using common hand tools provide the installer ease of installation and the vehicle owner hassle free use. Ideally suited for light towing and loads, these units are fully adjustable using the heavy duty U-bolts included in the kit using simple hand tools. If your tow and haul needs change, simply adjust the heavy duty U-bolts to suit the new load requirements.
Once installed and adjusted you are free to haul or tow with greater control and stability. Manufactured with heat treated ASTM 5160 alloy spring steel in our California based facility, these units are rated up to 2,000 lb. They are a great cost effective spring solution and can be adjusted independently for uneven side to side loads. Hellwig Products was founded in 1946 after World War II and has remained family owned and operated to this day, manufacturing all of its steel products in California's Central Valley.
In an era when many companies have moved production of their products overseas, Hellwig has remained steadfast in its commitment to produce its products in America. Thanks to Hellwig's commitment to quality manufacturing and research and development it also produces sway bars and other suspension components for companies that are looking for the very best. Hellwig has also helped to grow and develop the automotive aftermarket as a founding member of SEMA, having attended the first ever SEMA show in Los Angeles in the basement of Dodger Stadium.
