How Upgrading to Heavy Duty Leaf Springs Changes Your Vehicle’s Ride

If your leaf springs have worn out before you expected, you might want to think about upgrading to heavy-duty springs rather than just replacing what you have with the equivalent product. Before you make this decision, it’s important to think through whether there could be any downside to upgrading to heavy-duty leaf springs. Not every vehicle is used in the same manner, so each vehicle has its own needs when it comes to leaf springs, and knowing your usage is vital when deciding on what replacement leaf springs to purchase.

Heavy-duty springs will eliminate the sagging, wheel-hoping, swaying and squatting that you might be experiencing with your vehicle, and will add some overall stiffness to your ride. By adding to the stiffness of the spring, you’ll see better load handling and less leaf spring wear.

The Difference Between Riding with a Full Load and Riding Empty

Probably the biggest thing to note about using heavy-duty springs is the difference you’ll see and feel between driving with a full load and driving without a load. With heavy-duty leaf springs, you’ll be able to carry more weight and see less wear on your leaf springs, because they’re designed to handle the larger load without deforming to the point that their structure becomes compromised. Heavy-duty leaf springs are stronger and resist bending as easily as regular leaf springs so that the load will ride better without the leaf spring bottoming out. This can be a great help if you are hauling extremely heavy loads.

However, there is something else to consider about heavy-duty leaf springs. If you regularly travel without a load in your vehicle then the heavy-duty springs can sit a bit high when they’re not under load. This can cause some problems with the handling of your vehicle in certain situations. If you are rarely without a load, this is not an issue, however, if you routinely drive without any load then consider using SuperSprings instead, which will take any additional load only after the regular leaf springs carry their maximum load.

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.
