SuperSprings® are a unique and patented self-adjusting suspension stabilizing system for vehicles with rear leaf springs, designed to level loads and reduce body roll. SuperSprings® provide users extra load support and reduce body roll without compromising ride quality. They are manufactured using a variety of different sized springs to support multiple applications. All SuperSprings® are manufactured in the U.S.A. from SAE5160H high grade, shot peened steel.
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. SuperSprings automatically activate as loads are applied. They work when they need to without the need for manual adjustments.
SuperSprings work in conjunction with original equipment rear leaf spring suspension systems. They enhance the total suspension system. Using our customized tools, SuperSprings installations can be completed in less than an hour. Installation does not require disassembly of factory spring assemblies.
SuperSprings reduce rear end sag and sway without compromising ride quality. They reduce body roll and provide greater driver control. SuperSprings are a solution to suspension complaints such as: sag, sway, and uneven loads. They’re used in a variety of applications.
SuperSprings are designed with various shackles. The shackles will have 1, 2, or 3 bolt holes. The bolt holes allow the installer to adjust the SuperSprings. The higher the hole, the more pre-load tension, allowing the SuperSprings to start higher on the spring rate curve. Below is a chart showing the various bolt positions for a two-hole shackle.
- Service Body: Service bodies with tools and equipment add weight to vehicles. The factory installed suspension is not always ready to carry this extra and/or uneven weight in a level manner. Once tools and equipment are added, service bodies can easily cause a truck to sag in the rear, putting strain on suspension components and causing wear and tear on brakes, tires, and other components.
- Tow | Wrecker | Crane: These types of specialty trucks should not run solely on “un”specialty suspension. These trucks are expected to carry heavy loads and not always an evenly applied load. Without proper suspension enhancements, the service life of these trucks is cut short, resulting in increased costs and decreased safety. With an innovative suspension solution and fine-tuned spring resistances, your vehicle can accommodate the fixed and anticipated loads.
- Individuals: SuperSprings can be installed in approximately one hour by a skilled installer. Mechanically minded individuals will be comfortable and confident with step-by-step and easy to follow installation instructions that include drawings and photographs. SuperSprings are installed without disassembling original equipment spring assemblies.
- Fleets: SuperSprings are a great solution for individuals needing a suspension enhancement, as well as fleets looking to increase suspension abilities, provide safer ride control, and reduce their overall cost of ownership. SuperSprings protect your investment by limiting wear and tear that can result in future maintenance costs to other vehicle components such as tires and brakes. Fleet applications include: buses, delivery and freight, law enforcement, and more.
