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 robust leaf spring design that utilizes heat treated ASTM 5160 alloy spring steel, ensuring durability and stability under heavy loads. With a load capacity of 3500 pounds, it is designed to meet the demands of both progressive and fulltime spring rate applications, allowing for optimal performance based on vehicle load conditions.
