Knowing Your Suspension Limits to Avoid Overloading

Knowing Your Suspension Limits to Avoid OverloadingIf you are using your vehicle to haul heavy loads, there is one thing you need to remember: not all suspension equipment is created with a commitment to quality. Standard spring capacities can range from 1,500 – 3,300 lbs., and heavy-duty springs can typically handle even higher capacities. It is extremely important to know the capacity of your vehicle suspension system in order to avoid problems.

What Could Go Wrong by Overloading a Suspension System?

The main components of a suspension system are the springs, leaf springs, or coil springs. Both types of springs are made from strong steel that will resist the forces applied by the load on the vehicle and uneven road conditions to help produce a smooth ride. This is accomplished by the springs allowing the wheels and axles to move under the strain of driving so that the mechanical shock of going over a bump or encountering rough terrain is not transferred to the vehicle.

When these steel springs are pushed past their limit by an overly heavy load, many different problems can occur. The steel can stretch and distort so that it no longer has the ability to flex as well as it should, and cracks and fissures can occur in the spring steel limiting its capacity. Ultimately, a crack can cause the spring to break so that it will no longer function and the axle will bottom out on every bump.

What Can You Do if You Need to Increase the Load Capacity of Your Vehicle?

One of the most obvious answers is to install new standard springs with a higher load capacity. It is even possible to switch to heavy-duty springs that have an even higher load capacity than standard stock springs can accommodate. By increasing the load capacity of your springs, you not only prevent problems with your springs, but also with the attachment hardware that can also wear and break.

Another option is to consider SuperSprings or Timren Suspension Enhancement Systems. Both of these products are available to attach along with your current suspension products to assist in increasing the overall load capacity that your suspension system can accommodate.

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.
