High Quality Steel
SuperSprings are manufactured from SAE 5160H (51% alloy, 60% carbon) high-grade steel, shot peened to relieve spring stress and extend product life
SuperSprings use a dual-roller shackle. The shackle has an inner roller and an outer roller. As the factory springs extend to the rear, the roller facilitates the movement.
Using our customized tools, SuperSprings installations can be completed in less than an hour. Installation does not require disassembly of factory spring assemblies.
