Heavy trailers or bed loads can make a truck squat and lose stability. The TorkLift StableLoad Suspension Upgrade for Upper Overload Springs replaces small factory bump stop pads with thick 2-1/2" blocks that pre-activate your upper overload springs. This fills the gap between the spring and frame so the overloads engage right away instead of only when the rear sags. The result is a level stance, better weight distribution, and steadier handling when hauling serious weight.
When a load shifts or a curve pushes your truck around, these StableLoads keep things in check. The angled wedge design maximizes contact with curved springs to reduce side-to-side sway, porpoising, and body roll. In testing with 2,800 lbs of payload, trucks equipped with these pads showed clear improvement compared with stock suspension or air bags alone. Steering feels tighter, turns stay flat, and the ride stays composed even on uneven ground or over speed bumps.
If you already use air helper springs, adding StableLoads helps both systems work together. By taking some of the stress off the air bags, you won’t need to run high psi pressures that can make the ride harsh or unload your factory suspension. The StableLoads share the load so your truck’s suspension still does its job—improving stability and control while cutting down on bounce and sway under heavy loads.
Installing extra suspension support doesn’t have to be complicated. Each kit includes four StableLoad pads and necessary hardware that bolt directly to the frame-mounted overload bump stop brackets—no drilling required. Anti-rotation key tabs keep the pads secure once installed. It’s a straightforward setup that fits right for anyone comfortable with basic hand tools and wants a quick weekend upgrade.

WE had to get this exchanged as they sent the wrong bracket. But it didn't take long to get it resolved. Good Job. works great.
This has made a world of difference. Wish I knew about this product years ago!!
Another smooth purchase.

They work very well.
A very user friendly website from product review, research, ordering and tracking to delivery
Great communication from staff as alway s!
Product is good but had to cut the tabs off the pads for installation. Most people would not have the tools to do that.
Great product and very easy to install myself. I haven't had the opportunity to pull my fifth wheel yet, but will soon and looking forward to seeing a difference in the ride.
Great product and price with prompt shipping.
This has worked well for me in helping to level the stance of my truck when carrying the camper.
Works great, keeps truck level when the 5th wheel rv is hooked up, no sagging.
Does not work as shipped. Have a 2014 Chevy 3500 & the blocks are to tall. They touch without any weight in bed. This makes your rear suspension feel like its been removed. I called the tech line & they said they should fit but they did not. Brand new truck totally stock. After taking them out & cutting about an inch off with a band saw they work as designed.
One year and 15 miles later, the upper stable loads are holding up great. They have zero signs of wear. 2022 Cevy 3500 Dually
Etrailer has always delivered great service and quick delivery. My experience with them over the past 8 years has been flawless.

Very much satisfied with the torqlifts stable loads. Really noticed the improvement in sway and sag.
I am not seeing that much of a benefit from adding the Stable Lift Suspension upgrade. I still feel like I need to run as much air in my air bag suspension that I previously added to my truck. I do feel my unloaded truck rides much stiffer then before.
All I can write about right now is the installation and fit as it is still April in the Midwest so camping season is still about a month out. I purchased these to help with the body roll I encounter with my 3000# truck camper, and fingers crossed it will make my rig feel that much more stable rolling down the road.
The installation was really straight forward with the supplied instructions. I am not sure if it would have been as easy without the air bags I have installed as I was able to inflate those to 80psi to gain the clearance needed to install. But with the air bags inflated it was as simple as taking the old ones out and bolting in the new ones.
Couple of notes I could add for the manufacturer would be to simply remove the "tabs" on the side of the stops instead of making the customer perform this. Not as simple as they put it in the instructions. Not to mention when you remove these tabs it leaves exposed steel that inevitably will begin to rust. I hit the exposed spots with some cold galvanizing spray but that will only last so long.
The second item I would do is make the grade 8 bolt that mounts the stop an inch shorter as I struggled to be able to get a torque wrench on the front pair without trapping the wrench between the frame and the wheel liner on the truck.
By looking at the installed product I have high hopes that this will help out greatly with having that much payload in the box of my truck and the roll I encounter driving down the road.
Did exactly what I needed it to do. I have a heavy truck camper that gets a lot of sway under certain conditions. These extended overload pads are always engaged so the swaying gets stopped before it has a chance to start. Well built and easy to install. Hard to go wrong with these parts.
I haven't had any problems with these. I have a 2019 3500 Silverado single wheel that I wanted to take advantage of the overload springs without having to put a huge load in the bed. The stock mounts are so far away from the spring. Some may complain about the ride, but its a truck, I'm not concerned about the ride.
I haven’t used these with my camper yet (on order) but I’m not happy with these so far. First, why doesn’t Torklift take off the metal tabs instead of making the buyer do it? Wasn’t as easy as they make it sound. Second, I wanted to have a .5 inch gap between the Torklifts and overload spring so I wouldn’t have a rough ride during normal use (recommended by users). For the front bumper, this was not possible during trimming without hitting the metal structure of the bumper. I only have a quarter inch gap in the front....hopefully it will ride OK. Why can’t Torklift manufacture the bumpers to be make/model specific? Trimming these bumpers was a royal PIA. I will post a follow up after the handling performance is evaluated.
I tow a 13800lb fifth wheel with 2016 Chevrolet 3500 dually. Before the truck would sag, now with the TorkLift StableLoad Suspension Upgrade for Upper Overload Springs on it sits level. I do not take them off between towing so the ride is stiff when not towing.
Works like it’s supposed to.
Installed on 2016 GMC Sierra 3500 in around an hour. This has helped so much carry our truck camper. Body roll and bucking have been reduced to almost nothing running around on forest roads and getting into camping spots.

Product still functioning well. Glad I purchased.
These do their job well. We tow a toyhauler, and we'll use it without bringing the toys to camp. When that happens, the tongue of the trailer is pretty heavy, then add 150 gals of fresh water (in front of the axles) and the weight is increased! I installed these on my 2015 GMC 3500HD with 2" level kit in front, and now on those trips, my truck no longer sits lower in the rear, but sits almost level.
I trimmed mine down at a slight angle, as some people we talking about. And the blocks meet the overload springs flatter, and don't engage quite as quick.
Airbags may have a better ride, but these feel nice and solid towing.
Thanks for another on time delivery. Great products
Excellent service and prompt delivery unfortunately, this was not necessary for my situation. The lower stabilizers were sufficient in my case, but the product did arrive on time and excellent condition. I did not open the package.
Leveled out my truck with my 3300lb camper on it. Bringing my overload springs into the action before flattening the main springs.
