Long Travel Leaf Springs

The Dirt King long travel leaf springs are a 13 leaf progressive rate pack that are specifically designed for the 1999-2018 Silverado 1500 and Sierra 1500. These springs offer additional down travel, surpassing factory leaf springs, for enhanced articulation and conquering rough terrain. They also increase rear ride height by 1.5 inches, improving ground clearance and better ratio between upward and downward suspension travel. For optimal off-road performance, we recommend combining these leaf springs with the Dirt King shackle and hanger kit, bed cage, and bed cage spec bypass shocks. Durability is a key aspect of these leaf springs. Each leaf is individually painted and all other steel components are zinc plated for corrosion resistance. Anti friction pads separate each leaf to reduce noise and friction. The lower leaves have diamond cut ends for effective load distribution, reducing the risk of spring fractures. Additionally, shot peening each leaf helps relax the material, potentially doubling its lifespan. Installation is straightforward, they simply bolt into the factory location. U-Bolts are a one time installation use, do not reuse. Note that the Dirt King long travel leaf springs are tailored for performance and do not include an overload spring, which results in a decreased tow rating and payload capacity. However, removable air bags can be added to retain the vehicle's original tow rating and payload capacity. *Wheel placement is moved back 1/2" for adequate driveline plunge at full droop. Factory bedsides are not recommended because the repositioned wheel placement is visually noticeable. Most fiberglass bedsides accommodate for this or can be easily trimmed.
