Hellwig LP-25 Load Pro Series Rear Helper Springs by Hellwig Progressive Load Leveler. 3 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-tontruck.
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.
