Enhancing Factory Overload Springs

The lower factory overload springs on your truck are designed to help compensate for a large payload. When you are hauling a heavy load, your truck's standard leaf springs can't always counteract the weight of it. As a result, if you hit a bump when your suspension is fully loaded, the leaf springs will give and cause your truck to bottom out. The overload springs help keep this from happening by mounting beneath the leaf springs to provide points of contact for the stressed springs.


Gap Between Standard Leaf Spring and Lower Overload Spring

There is natural gap between your truck's standard leaf springs and its lower overload springs. This gap allows the upper leaf springs to flex a bit before making contact with the overload springs, but having this gap creates a situation where bounce (or jounce) often occurs. StableLoads are designed to fill the gap between your standard springs and your overload springs. This pre-activates the overload springs, ensuring that they are engaged from the start instead of engaging only when your leaf springs make contact, at which point you've probably already felt the jarring.


StableLoad Suspension Enhancement and Aftermarket Air Bags

By enhancing your lower overload springs in the way described above, you will notice less sway and body roll. This is due to the pre-loading effect of the StableLoads, which helps to better distribute the weight of your payload over the entirety of your factory suspension. This is the primary difference between StableLoads and many air bag overload systems.


With air bag suspension enhancement, the load in your truck is being taken on by the air bags. Air bags are designed to level your truck, and they operate as intended when they're under a normal load. But if you are hauling or towing a particularly heavy load, this type of suspension enhancement can create some problems. In order to get the correct amount of leveling and to ensure that your suspension won't bottom out, you will likely have to fill the air bags to a very high psi. Doing this effectively removes the load from your factory suspension. As a result, your truck's suspension is no longer able to operate as it was designed. This can lead to handling issues, such as porpoising, sway, or body roll.


If you currently have this problem with your air bag system, you can add StableLoads to your suspension and get the best out of both products. StableLoads are effective on their own, but they've also been tested with aftermarket air bag suspension systems. The two enhancements work particularly well together if you have a heavy payload. By installing StableLoads between your lower overload springs and your standard leaf springs, you are already adding support to your suspension to help prevent bottoming out, which air bags work to prevent as well. As a result, you won't have to fill the bags nearly as full, which means that they won't take as much of the load off of your factory suspension, thus allowing your suspension to function as designed - only better.


Quick Disconnect

TorkLift Fortress Propane Tank Lock

These StableLoads can be quickly and easily engaged and disengaged. The quick-disconnect design allows you to pivot the wedge pack - the piece that sits between the springs - in and out of position with a standard ratchet and 3/8" extension (not included). As a result, you can get a stable load when you're weighted down and then return to your regular ride when you're done hauling.


Tested and Proven Winner

TorkLift's StableLoads were tested against vehicles with no suspension enhancement and vehicles with air bags that were inflated to 100 lbs; and the results are clear. By adding StableLoads to your suspension your vehicle will ride smoother, causing less wear and tear on your suspension and tires. The trucks that were tested were loaded with 2,800 lbs. The degree of movement was then recorded, using an inclinometer, when the trucks encountered the 3 most common types of handling problems: side-to-side sway, porpoising, and body roll.


Preventing Side-To-Side Sway

Side-to-side sway is triggered when your vehicle encounters uneven ground, such as a pot hole, and the suspension gives way when it cannot counteract the weight of the heavy load being carried. This creates a side-to-side bouncing motion. As you can see in the graph above, air bags provide an advantage over no suspension upgrades. But the StableLoads offer dramatic improvement over both the standard suspension and the air bag suspension.


Preventing Porpoising

Porpoising is the rising and falling action your vehicle makes when driving over an object like a speed bump. Having too much bounce can make you feel like you're riding in the back of a school bus. As you can see in the graph, there is virtually no difference in porpoising between trucks with standard suspension systems and those with air bags. Only the StableLoad offers improvement for this type of problem.


Preventing Body Roll

Body roll occurs when your heavy load transfers unevenly as you navigate a turn, causing one side of your vehicle to lean dramatically. In some cases this can lead to your truck's tires coming off of the ground and it could even cause your vehicle to roll over if it is too top heavy. Again, according to the graph above, air bags offer no help with this problem. It is only with the StableLoads that stability improves.

Great product, the holes for the small bolts to stop it from twisting were just a hair to narrow for my 2005 f350 superduty. Had to bore them out a bit to get a fit. Other than that great and simple install



by:

Using this on an F350 w/ a Truck camper towing a 16 foot toy hauler. It's reduced the rear sag of the truck and provided better handling characteristics on the road. Good alternative to airbags.

The installation holes were made using the provided drill bits and a hydraulic jack to load the drill. Not too bad from a time stand point. Perhaps their provided drill jig may be easier or faster?

Some of the components had fit issues due to burrs that weren't cleaned up after machining. A quick hand deburr took care of that issue.

Overall a good product; despite the few minor fit issues. Installation instruction were clear as well.

These are absolutely going to improve your ride because they can be customized for your application whether that means you have a constant heavy load and need constant support or simply want to get a more balanced suspension if you tow or have a heavy...

  • Does Torklift StableLoad and RoadActive Suspension System for 2018 Chevy Silverado Do Same Thing
    The TorkLift StableLoad Suspension Upgrade # TLA7310S that you referenced basically allows the overload springs of the vehicle suspension to engage sooner to gain additional suspension support whereas the RoadActive Suspension kit # RAS4611 basically is like adding an additional leaf spring to the setup.

They will both work together but that might be a bit overkill so I would just pick one, the SumoSprings are my recommendation.

    The TorkLift StableLoad Suspension Upgrade w Quick-Disconnect # TLA7310S should fit just fine with the Air Lift air bag kit and RAS on your 2021 Ram 3500. My concern though is that you've either already worn out the factory suspension on your truck, you have something loaded well off-balanced, or you're overloading your pickup. It could also be a combination of the 3 as well. Normally air bags OR the RAS alone are enough to handle standard loads which is why I'm concerned you're using...

Both systems are very highly rated by our customers. I'd agree that air helper springs work best on loads carried in the truck bed.

The springs provide the additional support under heavier loads that your factory suspension cannot provide.

The SumoSprings adjust expand and compress vertically instead of to the sides in order to fully address the sagging issue.

I recommend using the 5K Rebel Helper Springs # SSR-301-47-2 and then you can use the standard StableLoad # TLA7310 or the Stainless Steel StableLoad # TLA7310S.
