Heavy loads can make the rear drop and steering feel loose. The TorkLift StableLoad Suspension Upgrade w Quick-Disconnect – Lower Overload Springs – Stainless Steel pre-activates the factory lower overload springs to evenly distribute weight and keep the truck level. The angled, tapered wedges slide into the gap between the leaf pack and overload springs so support comes on right away instead of after the springs have already sagged. That means steadier handling, better control, and fewer bottom-outs under load.
When towing or hauling, body roll and side-to-side sway can make things uneasy. StableLoad pads fill the natural gap in your suspension so your overloads engage from the start, reducing bounce and roll through curves or over uneven ground. The system’s hinged wedge packs maximize contact surface for solid, consistent support through ramps, potholes, and turns—keeping your truck feeling planted and predictable even when loaded heavy.
When the job’s done or the trailer’s unhitched, you can get back to a normal ride in minutes. Each wedge pack pivots on a hinge and disengages with a 3/8" ratchet extension (not included). Just rotate them out of engagement and you’re back to stock suspension comfort—no need to remove parts or fight stiff springs between uses.
Built from stainless steel, these StableLoads stand up to road salt, rain, mud, and whatever climate you run in. They’re made for long-term reliability with hardware that bolts onto each overload spring end—no drilling required when holes are pre-drilled. The kit includes four StableLoad units and all necessary mounting hardware for a secure install that lasts.
If you already use air bags, you don’t have to choose one system or the other. StableLoads complement aftermarket air bag suspension upgrades by taking some of the load off the bags themselves. You won’t need as much PSI to stay level, letting your factory suspension do its job while keeping handling tight and stable under heavy payloads or while towing.

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.
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've been using these for a year now on my Suburban 2500 and I like the ride quality and stability a lot. Sometimes engaging them can be tough... I find that unloading the spring I'm engaging makes it easier (driving onto a wood block on the opposite side is the fastest truck). I've had air bags and add-a-leaves on other trucks. This works better for less money, and perfectly preserves ride quality when I'm not towing and have the Torklifts disengaged.
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.
Quality Control is severely missing.
The torklift stable loads are easy to install, easy to engage and disengage as well. When I tow my 33 ft. 8000 lb travel trailer the engage the overload leaf springs and help to keep me le el.
I don’t notice that much of a difference with these. Although I did notice a reduction in left to right sway when they were engaged. I was originally running these with 5000lb air springs. We had so much porpoising when towing that I thought my wife was going to jump out of the truck on the highway. We tried all levels of air pressure to no avail. I took the truck in and it was advised I switch to the 2000lb bags and remove these shunts. The porpoising was significantly minimized. Not sure if it was all the bags or if these shunts contributed to the problem. I did not test the shunts both ways while towing.
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.
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.
I installed these on a 2016 F-350 short-bed crew cab pickup truck, on which I often carry a Lance 855S which nominally weighs about 3,000 pounds. I expected them to reduce side-to-side sway, which was a non-trivial issue in our travels, especially in gusty crosswinds at highway speeds. So, they DO in fact make a perceptible positive difference in the way the truck rides and handles under load. That said, the nature of the leaf springs on the F-series trucks from about 2010 onward severely limits the potential utility of the whole StableLoad concept. Why? Because there's hardly any space between the bottom (short) leaf and the next (full length) leaf! If you don't have some easy way to lift the truck off the axle (AirLift shocks or a pair of really tall jacks), you can only fit ONE of the StableLoad's 3 wedges into place. So, instead of adding 3/4" (3 wedges) to the point at which the bottom short leaf engages, you can only add 1/4" (1 wedge)! That one wedge makes a perceptible but not very significant difference in the truck's handling under load. So, I'm not sorry I did it, but I DID expect A LOT more benefit per dollar spent and per hour invested in installation (a soap opera for another time; make sure you have a 4' pry bar before you start the work) than I actually got.
This product has met my needs, it is simple to use. I installed them on my F250 and I pull a 37' bumper pull RV. My only complaint is that sometimes when disengaging the Torklifts they can be wedged pretty tight, I use a pry bar to spread the springs to help with this.
I have a 2015 F250 diesel super duty pulling a 13,000lb 5th wheel. I found that there was only a inch of remaining travel before hitting the overloads in the back and there was a significant drupe towards the back.
I looked at air bags, extended bump stops, Air bags are expensive and can have reliability problems with age, extended bump stops make your ride stiff when not pulling your trailer.
Then I ran into this product. The fact that you can disconnect the mechanism when not towing, is relatively low priced, the stainless steal version handles the northern states salt corrosion problems, and it is reviewed to be reliable until your leaf springs start drooping.
Well so far after a year of use, I found they do correct my problems, are easy to swatch over from loaded to unloaded in about 1 to 15 minutes, did not require any drilling in my Ford (other manufactures I have heard do require drilling 4 holes thru the leaf springs). It was easy enough for a 65 year old to install with a wratchet and some wrenches in 3 or so hours.
Yes I would buy it again.
I purchased this item to use on my 1999 Chevrolet Silverdo 1500 which I suspect had spent most of it's life hauling a fifth wheel trailer all over America. The springs seemed weak so I first tried installing coil over shocks on the rear. These proved to be defective and instead of going that route again I found Stableload. The installation was simple and quick and I am happy with the results. I leave the Stableloads in full time because I find my truck to be much more stable with less roll on curves and corners. I believe I have much better control of my truck during my daily commute over a rough, twisty backroad.
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.
I my opinion they provide firmer support, stability and less sway than airbags as they use the factory suspension more effectively. I’ve been using airbags for the last seven years and I am kicking myself for not using these sooner!
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.
Fit was good, though did have to some machine work.
Drilling out holes and filing some over looked production methods.
I also noticed that they are not all machined the same on the line up of the metal spacers.

I would have bought these years ago if I would’ve known how good they work…. They are nothing short of amazing!

If you read what torklift says about their Stable load devices for lower overload springs ……….. Believe it! I have a new Lance 975 camper that I put on my Ram 3500 SRW pickup and it handles amazing… I have heard people say that when you buy a camper, you should only install equipment as needed for hauling your Camper… I disagree! Before I had a 100 miles on my last 3500s I installed the Torklift stable loads, frame mounted camper mounts, and Fastgun tie downs… Torklift equipment has never let me down, and this last summer my Bride and I drove up to Alaska, by way of the Alcan Hwy ,,,, One thing more that I would encourage everyone to buy, that you can get here at etrailer, are Roadmaster front and rear sway bars . In my case The Stableload and sway bars have eliminated almost all sway… Don’t Cheat Yourself! Buy The Best Equipment!!
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!
Fantastic. I found a local shop to install them on my 2017 Colorado Diesel for 2 hours of labor. The difference was amazing. Previously I felt my boat was going to push me off of the road. With the TorkLift installed I am much more relaxed. It seems my truck is more relaxed too because I saw a 2mpg increase while towing.
I didn't realize that to disengage them it would require me to jack up the truck, but they are not bothersome driving around town while engaged.
So glad I bought these. I feel like it saved me from purchasing a new truck.
Adding the Tork Lift stable load suspension really helped my truck from sagging when I load up the in-bed camper. The ride is smooth and the truck handles very well. The installation was generally easy and the instructions were spot on. I highly recommend these if you want a stable ride and no sagging.
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.
Very easy to install on my 2018 GMC 3500 dually. Fortunately the holes were already there. They perform as expected while catting a heavy truck camper.
Installed the torklift stable load suspension kit on my Ford F-150. Was very easy to do following the instructions included or directly from the website. Once installed solved all of my suspensions sway by lifting the load and putting more weight on the front wheels. Immediately corrected the steering problems and distributed the load evenly so the truck was level. They are also very easy to engage or disengage from the leaf springs. No more airbags, or air shocks for me.
Easy installation, progress and easy to understand instructions. The assembly was actually very enjoyable kind of like putting together a puzzle when you were a kid I had intended on using the upper stabilizers, but after the installation of the lowers, they worked so well the uppers would not be needed Strongly recommend this product

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.
