SuperSprings suspension helper springs are a unique and patented self-adjusting system for stabilizing rear leaf springs on vehicles. These springs are expertly designed to evenly distribute loads and effectively reduce body roll. Crafted from SAE5160H high-quality, shot-peened steel, SuperSprings utilize a range of different spring sizes to cater to various automotive needs. Additionally, these springs come equipped with shackle options featuring 3-bolt holes for easy adjustment. The higher the hole, the more pre-load tension is applied, ensuring SuperSprings start at a higher point on the spring rate curve. This results in superior load support and minimization of body roll while maintaining a smooth and luxurious ride.
