Enhance load capacity with advanced leaf spring technology.
The Hellwig Helper Spring Kit is engineered to improve the load carrying capacity of full-size pickup trucks and vans. This kit features a leaf spring design that utilizes heat treated ASTM 5160 alloy spring steel, ensuring increased spring rate and stability under heavy loads. With a load capacity of 3500 pounds, this spring kit is designed to meet the demands of both progressive and constant rate applications, providing versatility for various loading conditions.
The progressive spring rate design activates as the vehicle load increases, allowing for a smooth transition in resistance. In contrast, the fulltime spring rate design reacts immediately to the load, ensuring minimal compression under weight. This dual functionality makes the Hellwig spring a reliable choice for enhancing vehicle performance.
Installation is straightforward with a simple bolt-on design that requires common hand tools, allowing for quick setup without the need for specialized equipment. The kit is compatible with 2-1/2 inch or 3 inch wide leaf springs, making it a versatile option for many vehicle models. The Hellwig Helper Spring Kit is a practical solution for those seeking to maximize their vehicle's load capacity while maintaining stability and control.
