Hellwig 9511 LP-35 Heavy Duty Leaf Kit for 1972-2006 Ford E350

LP-35 Load Pro Series™ Rear Helper Springs (9511) by Hellwig®. Constant Load Leveler. 4 Leafs Stack. This is a set of secondary helper leaf springs designed to add up to 2,500 pounds of load support to restore comfort and stability at the rear of your “1/2-ton” truck. The 3-leaf design progressively adds support as OEM leaf springs become loaded and compressed. Crafted from heat-treated ASTM 5160 alloy spring steel for maximum strength and resilience, these feature a spring rate that becomes firmer as pressure increases. Recommended for heavy hauling, work truck use, or pulling a 5th-wheel RV trailer, these maintain proper ride height and prevent original springs from sagging due to sustained load compression. Drilling may be required.
