This is a set of secondary helper leaf springs that add 2,500 pounds of load support while providing the quietest ride possible. Pro Series adds polyurethane cushioning blocks (sold separately -- see Product Options) that eliminate any rubbing, friction, and noise between leaf ends. The 2-leaf design progressively adds support as rear 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. Maintains proper rear ride height, prevents original springs from sagging due to sustained load compression, and helps reduce bouncing during towing. Fitted U-bolts and related hardware are included for mounting. Drilling may be required.
