Helper Spring
Hellwig Helper Springs are designed to sit on top of the leaf springs at the rear of your truck and work in conjunction with the stock spring pack to effectively increase the level load rating of your truck up to the vehicle’s gross vehicle weight rating. Hellwig Helper Springs are adjustable, easy to install and come with all the necessary hardware to make installation painless. Hellwig offers several types of Helper Springs, each with different load capacities and applications in mind. Like all of Hellwig’s steel products, they are forged in California in Hellwig’s ISO9001 certified factory and come with Hellwig’s limited life-time warranty.
