Enhance load capacity with advanced leaf spring technology.
The Hellwig Helper Spring Kit is engineered to improve the load carrying capacity of full-size pick-up trucks and vans. This kit features a robust 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 innovative design of the Hellwig springs allows for a progressive response to load, meaning that as the vehicle's load increases, the spring's resistance also increases, enhancing stability and control. Alternatively, the fulltime design offers immediate response to load, compressing minimally under weight. This dual functionality makes the Hellwig Helper Spring Kit a reliable choice for those seeking to maximize their vehicle's performance.
Installation is straightforward with a simple bolt-on design that requires common hand tools, allowing for a hassle-free setup. Note that mounting hardware is required for installation on 2-1/2 inch or 3 inch wide leaf springs. This kit is a practical solution for those looking to enhance their vehicle's load management capabilities without compromising on ease of use.
