Heavy payloads can make the rear of a truck sag and throw off handling. The TorkLift StableLoad Suspension Upgrade for Upper Overload Springs replaces the small factory bump stop pads with thick, angled rubber blocks that fill the gap between the upper overload springs and the frame. By pre-activating the overload springs, they engage right away instead of waiting for extreme sag. That keeps the truck level and distributes weight evenly across the suspension for better control when hauling or towing.
Uneven ground or tight curves can cause side-to-side motion and body roll that wears you out behind the wheel. The StableLoad’s angled structure maximizes contact with curved springs, and anti-rotation key tabs keep each pad locked in place. The result is noticeably less sway, bounce, and roll—especially when carrying heavy campers or loads with a high center of gravity. It gives a planted, solid feel on highways and job sites alike.
Running air bags alone can mean filling them to high psi just to stay level, which can pull too much load off the leaf springs and make handling feel floaty. StableLoads add mechanical support between your frame and springs so you don’t need as much air pressure in the bags. The two systems complement each other, keeping your factory suspension active while cutting down on porpoising and side-to-side motion under heavy loads.
This kit bolts directly onto each frame-mounted overload bump stop bracket—no drilling required. Everything needed comes in the box: four StableLoad pads plus all mounting hardware. Installation is straightforward for anyone comfortable with hand tools and a jack. Once mounted, there’s no maintenance required, just consistent support every time you load up.

2010 Ford F-250 FX4, 4.5" ICON suspension lift, 6.8 V10
Install is pretty easy, raise truck with a jack to take the load off the springs. WD40 and a screwdriver to pry out the old isolators. The front mounts are easier to install with more access. You can flip the bracket upside down to get more depth out off it which is what I did. However I had to modify the rear ones to mount them. The tab that sticks through the curved bracket on the rear curved mount hits the factory mount and rocks around. I had to grind a 1/4" off of it to make it sit flush. Also some larger washers would have been nice but for sure not a deal breaker.
The truck is definitely a little bit more bouncy, I have a camper shell and about a thousand pounds of tools in it at all times. I commute in the truck about 60 miles a day over some winding mountain roads, it definitely handles the corners WAY better than it used to, you do feel a lot more of the small road bumps more, but once again not a deal-breaker.
These TorkLift enhancements are as they claim. Along with the TorkLift axel bump stops, these totally have completed the stabilization I was desiring. No more swaying and the leveling of my rig is where I want it with a 5,000# truck camper pulling a load. These would have received a 5-star rating if the prices were not so expensive, but they are supposed to have a lifetime warranty.
First thing first is that you need to get away from delivery through the United States postal service, I was 4 days late getting my delivery on time to use them on the before leaving. I will request fed ex next time, I will update once I get the prod6in my hsnds
I purchased these stable loads for my 2022 F350 when hauling my 2021 wolf creek truck camper. The wolf creek was weighing down the F350 by a few inches and the family and I were going cross country. I considered air bags but didn’t want the potential issues of failure. The stable loads are working great. We are a family of four and did an 18 day cross country trip with the camper and they performed very well! I may still end up with air bags but the stable loads made the trip much safer and added a much desired degree of stablility! The fact they engage the overload springs of the truck make these fantastic for side to side stability. Air bags are not a necessity now. This pic is from the last day with a bunch of Kentucky whiskey and beer and other souvenirs in the rig!
The biggest problem I had was leveling and jacking up the truck and camper as I
have no flat surface to perform the installation. Once the load was off, the next issue was removing the factory bumps. It was a minor problem not solved by WD40. I broke out a small propane torch and heated and softened the originals and easily removed them. Obviously, make sure there are no brake lines, fuel lines, etc. nearby. It was
then very easy to install the Torklifts.
It was worth it installing them. I noticed reduced "porpoising" and less lean in corners.
In general, with my 3800# camper mounted, the ride is more "crisp" and precise.
I've include pictures of the original and the installed Forklift TLA7200
did not use these stableloads yet. Will try the factory air bags and then determine if the stableloads are needed
I wish the washers and nut were grade 8; nevertheless, it improves the ride by engaging the upper spring on heavy loads, no bouncing or rocking any more. However, if you have the Ford scales, it may affect them. I ended using addtional grade 8 wahsers (flat, lock) as well as a grade 8 nut plus a grade 8 nylon nut. My ride is a ‘24 F350 DRW and use it to tow a Fiftg wheel and now a truck camper, Lance 960; also for those “honey do’s” must do ….
1 stableload had a little space between the rubber and the mounting plate will try it tho hopefully it wont fall apart you should provide taller nuts these were a little too short
I added this to the rear suspension which already had the Timbren FR250SDE Kit installed and the result was additional stability and load leveling at a reasonable price that did not require a pneumatic pump. When unloaded the truck sits normal. I have a slide in camper and pull a trailered Bronco with a combined wt. of 16k lbs. Ride is unaffected when empty and is comfortable when loaded.
Well overall I gave them a 4 rating. Great website complete with installation pictures and video. Shipping and messages regarding orders are always updated daily. The only negative are the tabs on the upper Stableloads tabs are machined wider than the factory bump stops requiring me to press them closer together so that they would pop into place. Thanks for allowing me the opportunity to again do feedback on this product.

After a year they are still doing what they are supposed to do and that is engage the upper overload springs sooner than the factory bump stops allowing the truck to maintain level. Hold up well even in salt and sanded roadways during northern tier winter travels.
I purchased the Torklift upper loads for our 2025 GMC DRW 3500, for support with our new truck camper.
I did have to cut 5/8 inches off of each one prior to installation which is what Torklift suggested. The supplied grade 5 jam nuts were a little shallow so I bought some thicker hex nuts. Otherwise, once I jacked up the rear to create a little space for installation, it went very smoothly.
Very pleased, and hoping this will help to avoid any sag.
I just installed them on my 2015 F350 20250209. I can feel and hear the difference from my bed when I go over bumps and railroad tracks. Overall it took me over 45 min to an hour due to not having the right tools. Thank you

Hey Larry! I'm happy to hear that the install went so smoothly. Going over railroad tracks can be brutal sometimes, but sounds like it wont be for you anymore!

No issue, love it on my truck.
Perfect! Took more time to get the stock one off then put these on my 24 F350 LB,Godzilla
Super fast shipping when I needed it.
Super easy install. I had to trim the forward Stable Loads. No problem with a sawmill and fresh blade. Paired with the Hellwig Big Wig rear stabilizer and airbags, my truck handles amazing with the camper on board. The instructions are very good. The installation took 2 hours. That includes removing the felt wheel well liners.
I installed on a Chevrolet 1 ton to engage overload springs without squat. Works as advertised. Less roll and more stable all around. Slight fitment issue and needed to cut off a tab of metal, but torklift support is responsive and helpful.
I was expecting these to completely stop the sway of my truck camper, but it did not. Yes, the spring is engaged faster when loaded with my camper, but I still have a lot of sway. It seems to shorten the amount of sway time, but does not eliminate it completely.

I am happy to hear they are helping to support the suspension. The StableLoads do help to reduce sway once the sway has started. They are not designed to prevent sway unfortunately. Have you ever thought about replacing the sway bar on the Ford?

No change
The upper stable loads really close the gap between the stock, bump stops, and the overload springs and all, but eliminate squat. They were fairly easy to install, especially once I lifted the body up and took any load off of the springs.
Well built and as described. We also added the lower Stable Load kit. Leveled out my truck with our camper on. This is the way to go! We also have airbags but do not need them. Highly recommeded if you are hauling a camper for safety.
We put these on my SRW gmc 3500 put truck camper in and hooked up trailer took off for Alaska. I adjusted air bags just enough to take some pressure off of overloads while keeping them engaged. The torklift’s worked well and held up to the 14k trip.
Great fit for 5th Gen RAM 3500 Dually, even though Torklift website doesn't have a listing for this truck. I did a little trimming on the rear set as per step 4 in the instructions. Great fit and better quality ride with the Lance 1172 loaded up.
The box was labeled A7200, for Ford F350, but had A7202 kit inside, for chevy 3500.
I notified customer service. They sent a return label and said they would send correct kit. I am still waiting and tracking does not seem to be working on the new shipment.

Let me look into that, I'll get it taken care of!
The stable loads made a significant difference in the ride with my Host Camper. I had already upgraded the shocks, added airbags, and installed a sway bar, but I still experienced side-to-side rolling. However, after applying the stable loads, everything improved considerably, and I gained much more confidence when driving on rough roads and corners. Before, it was uncomfortable at times, but now it’s a dream come true. Such a small and easy change had a profound impact.
Arrived in reasonable time, Look well made and and fit well. I haven't used the truck with a load on it but I can see that they will work well and not alter the ride of the truck when not loaded or have tongue weight from my trailers. Not inexpensive but much cheaper and easier than more springs being added.
1993 Ford F-350 4X4 Crew Cab. These things work great!! Easy to install. With my 4000 lbs Lance sitting in the bed of my Rig, my rear suspension would sag. My Rig still ran and felt great but she had a saggy butt and nobody likes a saggy butt. The TorkLift’s eliminates the 4” of sag that I had.

That's one heck of a set up, Mark! Glad these are helping get rid of that saggy butt! ^___^ What's next trip you have planned?
After about a year with both the Roadmaster Rear Anti-Sway Bar and the TorkLift StableLoad Upper Overload Spring Upgrade on our truck camper setup, my experience has been mixed.
With the StableLoads, some of the mounting screws eventually fell out. I contacted etrailer expecting the issue to be handled under warranty, but instead of taking care of the replacement directly, I was referred to the manufacturer. Considering the age of the product and that it was purchased through etrailer, I was disappointed with how the warranty issue was handled.
As for the Roadmaster 1-1/2" rear anti-sway bar, it is a very solid and well-built product, but in our particular application I honestly haven't noticed a major difference in body roll while taking turns with the camper loaded. I have driven the truck both with and without it, and the improvement was much less noticeable than I expected.
Neither product is necessarily bad, but based on our experience, the improvement in handling hasn't been significant enough for me to strongly recommend them given the cost.
Do you have a question about this Vehicle Suspension?
