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.

2018 Chevrolet Express Van

I thank you guys for installation videos and the ease at which things can be installed. I thank you also for great customer seervice and support. The TorkLift Stabilizers work incredibly well and I am very happy for what little effort it took to install them!


The lower StableLoads worked as advertised--considerably reducing sway and increasing ride quality with a fully self-contained hardside camper on board. 'Pleasantly surprised with results, but with price...not so much!


Useful, but very expensive for what it does. It will let your truck sit a bit more even under load, but it won't make a 150 into a 250. It's a spacer that let's your overload springs become a part of the regular suspension. I have a truck camper designed for a Ford f150 weighing 1700 pounds. These spacers helped, but had to go with air bags also to get the truck even. On the positive side, you can easily slide these out of the way when not hauling for a better ride.


Works great! I tried Timbren bump stops and air bags, both caused a harsh ride. The Torklift is easy to install and causes your overload spring to work as designed. When not towing, you can de activate it and go back to a normal ride very easy.


I am totally satisfied with the way the product installed and how it performs on my 2018 Ram 3500 dually with the Lance 1172 slide in camper on it. Would totally recommend it.


The stable loads function as advertised.
By engaging the overload spring the rear of my truck has almost zero squat when I load my camper. I belong to several online camper forums. Most of the members seem to push air bag, but constantly complain issues. The stable loads have functioned well and my trucks suspension works as designed.

2020 Ford F-150

Our setup: Truck - 2020 Ford F150 with heavy duty tow package. Travel trailer 600 lb. + tongue weight and 4,800 lbs dry weight and Anderson No-Sway Weight Distribution hitch.
Purchased all late May 2020 and took a number of relatively short camping trips and found the front end of truck to feel light which affected steering and front end sway. Had a 3,000 mile Yellowstone trip planned for early September 2020 but considered cancelling it due to what I felt to be an unsafe handling situation. Semi's would really pull and push our setup when passing us. After researching towing issues and products we choose TorkLift StableLoad Suspension upgrade. After installation we took a couple of late August trips to test the results. I was amazed on how much improvement theses small devices made in handling and stability. We took our Yellowstone trip and all went well. No concern over handling so we felt so much safer than prior to installation. In all honesty, if the handling had not improved we would have cancelled our long journey. What we learned through our experience is that it is so much about reducing rear-suspension sag. The TorkLift upgrade did in fact significantly reduce that sag which put weight back on the front suspension thereby improving steering and handling. Once installed the TorkLift devices are simple to engage and disengage. Note, that this review and our experience includes the use of a weight distribution hitch which I consider essential to a complete travel trailer towing package.
Our only suggestion is that the installation instructions were of better quality. Not much to ask considering the price of the product (but well worth the $$ given the results).

A year later and a number of camping trips. Product continues to provide improved handling as described in our original review.
John a - 09/20/2021


I received yesterday but need better packaging for the parts, I opened box and 100’s of screws, washers, bolts etc were loose. The ziploc baggie is not sufficient for all these parts. I will spend today trying to see if they are all there… there was plenty of gap in the shipping box for these to fall out. I’ll be surprised if they are all there. 2 star for packaging.

Goodness, I will share this review with our shipping department. Customer service will be in touch to make sure that you have received everything.

2016 Ford Edge

I would rate this product five stars other than a couple of minor, somewhat cosmetic issues. All of the Stableload components fit perfectly. This issue I had was that on every base plate at the end where the rubber grommet goes in is a manufacturing "ridge" left in the edge of the plate. It is very sharp and on every plate I needed to file off that sharp imperfection that could have resulted in a bad cut while handling it. The other very minor issue was one of the 3/8"x1 1/4" bolts somehow cross threaded itself in the middle of the bolt when tightening so I had to go buy another SS bolt and nut at the hardware store to complete the project.

Ford F-350 Super Duty

I received the stainless steel version to avoid corrosion. A well built, sturdy product. On my F350, I had to do quite a bit of jacking and use of crowbar to get it in. I haven't towed with them yet and they do not change the ride by leaving them engaged. This should solve the porpoising problem we have towing a fifth wheel trailer.


Some of the bolts are already rusting. When not engaged on my 2016 3500, the leaf springs still come into contact with the bolt head too (has flattened some of them) and makes a crappy clanking sound going over bumps). The product itself does help the stability when my truck camper is loaded, however, I’m still surprised that after 1 year they are already starting to rush.

Ford F-150

I put it on a F150 for hauling a slide in camper. But sold the slide in and got a bumper pull. Even without the equalizer hitch , these held the back up pretty good. Without them it would have dropped about another inch in the back. I tried it both ways. While we had the slide in, it took alot of the boat in the water feeling away in turns. It was a good investment.


Absolutely excellent, would but again and I recommend. They engage your overloads dinner and the truck corners and handles loads Joe it sold have from the factory!

GMC Sierra

I used the product to level 3/4 Sierra and counter trailer tongue weight. A perfect solution. Easy to install and obviously durable.


Easy to install


These things were very pricey but come really well recommended so I bit the bullet and ordered them. The alternative was having an RV shop install an entire system of air bag suspension. Torklift makes these and I ordered the more expensive set which is all stainless steel but considering where it gets bolted under your truck its worth not having everything frozen with rust a year later. The instructions were actually very poor on this item but it was simple enough to figure out on my own although I had to call Torklift twice. I was done in an hour or two and it works perfectly.


I always have great success ordering from etrailer and this in no exception! As always, thanks for being a great on-line retailer.


Love this product! Works exactly as advertised and you don’t have to worry about screwing around with airbags. Simple and ingenious. Recommended them to a couple of buddies who love them too.

Have used this product for a year now. Would not put a load on my F150 without engaging the Torklifts as they help that much and provide a great deal of confidence. I spent the extra money for the stainless version and would do it again.

Ford F-250 Super Duty

We have a F-250 with a 3000lb truck camper. The stable load made a significant improvement to the ride. Cornering was especially better.


In the past I have used airbags to haul my Lance camper. I purchased the upper and lower Stableloads, and like them better due to side to side motion, plus they are less expensive.


I was totally amazed how much better my truck handled with my truck camper on it. these torklifts work exactly the way they said they would.


Item was extremely easy to install . Take the time to watch the installation videos [online] or request the video from torklift. I advise assembling everything prior to going to the vehicle.
I have yet to haul with the Stablelifts engaged but can already tell a difference in handling.

2006 Chevrolet Silverado

Worked as claimed. Easy to install on my 2006 Silverado 2500. I have a 17' Cabover that sits up quite high. StableLoad really helped with my ride.


Got the TorkLift StableLoad Lower Overload springs in November 2019. They worked great with my 2013 Ford F-150. They corrected a sagging problem with the stock suspension while pulling a 31’ travel trailer. Leveled the truck & trailer very well. Used them for several thousand miles; sold them a couple of weeks ago on eBay & got 2/3 of my money back after selling my F150; replaced it with a new F250.

2016 Ford F-250 Super Duty

I have a 2016 F250 and tow a 5th Wheel. Once I put these on the ride was better and most of all the little bit of sagging I had on the bed was totally gone. Thousands of miles later the ride is still fantastic.
