Leaf Springs or Super Springs: How to Decide

Leaf Springs or Super Springs: How to DecideHaving a large vehicle or truck often means you will be using it for some heavy-duty operations like attaching a snowplow or hauling a heavy trailer. For tough duties like this it is important to have a suspension system that can handle the load, and the factory-installed leaf springs are very often not up for the task. When your suspension system needs an upgrade, there are two good options available: upgrading to heavy-duty leaf springs or adding Super Springs, but which is the right option for you? Here is some helpful information about how each one works to help you decide.

What are the Benefits of Heavy-Duty Leaf Springs?

Heavy-duty leaf springs are used as a replacement for your existing leaf springs, but are designed to take much heavier loads. By installing a heavy-duty leaf spring, you’ll have thicker leaf springs that can hold a larger load without sagging and breaking as a regular leaf spring would do under the heavy load.

The use of a heavy-duty leaf spring is extremely well suited for such applications as installing a snowplow to your truck where an additional load will always be present on the leaf springs. The heavy-duty leaf springs never need a break from these types of loads.

What are the Benefits of Super Springs?

Super Springs are designed to sit on top of the leaf springs that are already installed on your vehicle. They are only engaged when the load on the leaf springs becomes too much and the leaves flatten out from the load and the Super Springs take over the remaining load. This is ideal for an application where you will occasionally have a heavy load, but often ride empty. In this way, you do not have a problem with sitting too high when riding empty. If you are occasionally adding a heavy trailer that would cause your regular leaf springs to bottom out, but normally ride without it, Super Springs are definitely something to consider.

SuperSprings are progressive in nature in that they work on an as-needed basis. The installed springs are under nominal tension even when the vehicle is unloaded. This is so there is no rattle or noise and the patented rollers will activate automatically.

As a vehicle with rear leaf springs comes under load the factory springs react as they are designed to. The center of the springs move vertically causing the overall leaves to flex and flatten out. This movement in the factory spring activates the SuperSpring through the rollers at the end of each leaf. Because the SuperSpring rollers aSupersprings Shacklere under tension, a movement in the factory spring causes them to move, seeking their new point of least resistance. This simple roller principal allows the SuperSprings to activate and deactivate automatically, free of any manual adjustment.

The SuperSprings are length specific to fit varying sized leaf springs. In addition the different lengths typically are manufactured in light, medium and heavy duty strengths. The sole adjustment on the SuperSprings is found in the roller shackles at the end of each leaf. The typical shackle has two bolt holes, as shown in the diagram below though some single hole and three holed shackles are used. The most common installation involves positioning all four rollers in the lower (furthest from the eye of the SuperSpring / closest to the ground) bolt holes. This ensures the least amount of preload tension on the SuperSprings and keeps the vehicle closest to its original factory ride conditions. Upper bolt holes may be used if additional lift is desired in the vehicle; if clearance from obstructions is required or if the installation is on an older vehicle with some fatigue in the springs.

SuperSprings enhance load carrying capacity, handling and towing. Do not load any vehicle beyond the manufacturers gross vehicle weight rating.
