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.

2014 Dodge Ram Pickup

When I first got this rig(2014 RAM 3500 DRW carrying a Lance 992 4K pounds), it already had the upper stable loads and I still experienced porpoising, sag and sway. Then at the end of last season I notice we were listing to one side. It turns out the upper stable loads had disintegrated. I had to buy new ones because the lifetime warranty is non transferable. So While looking into that I saw the lower stable loads and decided to get those too. After I first installed the stable loads(along with the new upper stable loads) I took the rig for a test drive and I could tell immediately there was improvement with handling as could my wife. But I was a little skeptical, thinking I was just being overly optimistic. So I decided to wait until I had a more thorough test before writing a review. We've been boondocking in the Southwest for the last three weeks(geographic distancing) and have been driving on a lot of bumpy roads and a lot of washboard roads, interstate and state highways, you name it. I think I've hit all the road conditions that have caused us problems in the past. Problems I used to have that I haven't had an issue with yet: Porpoising --- This is very surprising and fantastic. We experienced porpoising at least once during every extended drive. I'm pretty shocked that I haven't had it happen in three weeks. I really hated porpoising. Sag - People would flash their lights at me at night because the sag caused the front to tip up enough to make it appear as though my brights were on. This is not happening any more. Sway - We used to experience a lot of sway and this has disappeared as well. Maybe if I drive like a maniac I'll get some sway, but I'm not going to risk it. It's such a comfortable ride now and I'm genuinely surprised. It seems like a cheap and easy fix and I don't understand why truck manufacturers don't offer this for their vehicles. 786889

2014 Ram 3500

My review is specific to the Stable Loads for my 2014 Ram 3500 SRW 4x4 Diesel Pickup truck. First, the package arrived a day ahead of the delivery schedule. Inventory of the kit showed it was complete and matched the list of contents included. The overall impression was that this is a very well made and manufactured system. The stainless steel option seems to be well worth the small added cost. The instructions from TorkLift are a little vague in places so here are a couple of pointers. First, I needed more spacer washers than were provided with the kit due to the thickness of the lower spring. I was short a total of 4 washers. It seems like this is a simple detail that others should have made TorkLift aware of. Surprisingly, I found no mention of this on-line or in videos. Another vague area is regarding the orientation of the bracket on the spring pack itself. on my truck, I needed to install the stable load to the inside - between the frame and the spring. I tried to install the rear stable load to the outside (tire side) but found that even with stock size tires, the clearance was too close for my comfort (less that 1 inch between the bracket and the tire sidewall. On my truck, there is a wiring harness along the bottom of the frame at the rear drivers side that had to be adjusted closer to the frame to provide clearance for the bracket. Otherwise, all 3 of the other mounting locations had adequate room for the inside mounting location. Also, for my truck, using two of the three wedges provided the right thickness for proper engagement. Another note is that for my Ram, I did not have to drill out the springs because the rubber pad is installed into a hole on the overload spring. The hole is slightly larger that the diameter of the mounting bolt. This did not seem to affect the installation but again, it seems a bushing of some sort would be a good addition to the kit. Installation time was a bit longer that what I have seen mentioned by others but still, a few hours and it was ready for a test drive. With the stable loads engaged, the empty ride is a bit stiffer that stock but not objectionable. The real test will be with the 3000lb+ camper installed. That review will have to wait. E Trailer was great to order from and had the best price I could find on-line. This is the 4th or 5th time I have ordered from E Trailer and have never been disappointed. 769503

Hasn't been much time for me to really write a review, but I'll write one as requested. So far what I've noticed after install is the rearend feels tighter, the good kind of tight. Haven't towed with it yet that won't be for a while either, but suspect if it is already making the suspension tighter it should definetly make at least some kind of difference during heavy load situations. 176030

This is the 3rd time I have purchased the Timbren Rear Suspension Enhancement System. I have always been satisfied with the ease of installation and the effectiveness of these springs, whether I am pulling a tow behind trailer, a 5th wheel or carrying a load in my truck. The only thing I did different this time is I purchased the Timbren Rear Suspension Enhancement System with the TorkLift StableLoad Rear Suspension Upgrade. I will post a review on the complete purchase once I install these in addition to the Timbren Rear Suspension Enhancement System. 671115

Review from a similar StableLoad in Vehicle Suspension


UPS delivered with packaging intact. L & R Wedges are wrapped separately and labeled. Hardware was contained in a sealed bag. 2 pieces were damaged, easily replaced at the hardware store. Instructions were reasonably clear, but there is room for improvement there. Installation : Installation was on a 2018 Chevy Colorado and straight forward. There is the option of installing the units inboard or outboard. Inboard installation on the Colorado would have resulted in insufficient clearance between the spare tire on the rear units, and the fuel tank on the front. Outboard installation resulted in minimal clearance with the mud flaps on the rear, and contact with the brake line and supporting bracket on the left front. Some backyard engineering with waterpump pliers was required to create adequate clearance. Use: Engaging the wedges is not possible with weight on the axle. The truck must be jacked up enough to unload the springs before rotating the wedges into position. I haven't had a chance to load up the truck and hook up the trailer. I'll provide follow-up when I do. 612376


Comments
The wedges do level the truck when loaded up and towing the trailer. The truck must be jacked up to engage or release. They squeek & creek when engaged, but they do the job.

After using the stable load TLA7310 for almost a year, I am still very happy and satisfied with the product. Easy to install and like being able to engage or disengage the stable loads depending on my load. Mine are installed on a RAM 3500 dually crew cab and I haul an Arctic Fox 990 camper and sometimes trailer a boat with the camper. The ride was greatly improved with reduced amplitude on the floating bumps and reduced sway on turns, but I felt I needed a little bit of lift in the rear. At night I was getting some high beam flashes from oncoming traffic which told me the rear was sagging a bit. I added the F2560 Firestone airbags to my truck which I only need to inflate between 15 to 50 psi to give me about an inch of lift. In my opinion the stable loads and airbags complement each other and work well as a suspension system enhancement to the factory springs. Both products can be "deactivated" with no load which is important to me because I will often drop the camper at the campsite and drive significant miles with no load. 642535

I have the upper and lower stableload suspension upgrades on my 2001 2500 Dodge Ram diesel pickup. I had these installed before a cross country trip with my heavy gooseneck horse trailer. There is significant improvement in handling and steering. The truck now hauls the trailer with much less stress as the weight of the trailer seems to be much better distributed. The truck bed used to sag a bit when I attached the trailer (even with factory overload springs) and now that's not happening. I believe that there is possibly less wear and tear on the rear tires as well. I am pleased with this upgrade and have recommended it to my horse hauling friends. I haven't bothered to disengage the lower stable loads so the ride is stiffer when there's no load, but it's really not an issue right now. 287508

Installed StableLoads on a 2017 Ram 3500 dually that carries a 4500lb (wet) truck camper and pulls a 24' enclosed car trailer. The StableLoads are easy to engage/disengage depending on load, and have none of the issues common with airbags. In combination with a Hellwig BigWig sway bar, the truck rides well and handles well, even with the high center of gravity with the camper. 556140

Product is excellent. I ordered, double checked to make sure it was right model for my truck and then wrote email back to etrailer to triple check the order. When the stableloads arrived, they would not fit my truck without modification. I have a 2012 Ram 3500. The stableloads were too wide and thus I had to modofy in order to keep my original pads along with the new stable loads to make it fit my truck. 405552

Review from a similar StableLoad in Vehicle Suspension


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. 647215

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. 373991

I recently ordered a set of Torque-Lift Stable Load for my Dodge P/U. They were delivered while we out of town, but the delivery was extremely fast. I plan on installing them tomorrow. A friend installed a set on his Dodge and was very satisfied with the performance. That was enough for me to order some. Thanks for the quick service.

Review from a similar StableLoad in Vehicle Suspension


Having been in the auto/truck repair business for over 50 years, I thought this would be a good Idea so I tried it. I could have made my own but it would be a lot of cutting and drilling because it is so many pieces. I used it to add capacity so I could haul my camper that I purchased three states away and had to pick up. I used 2 of the 3 plates because there wasn’t enough room for three. It did very well like that but after I got back I added the 3rd plate figuring I could use the third one by just jacking the truck slightly before engaging. I thought all three woul be needed once the camper was full of water and gear. I am enclosing a picture of how ti drill the springs with using the vehicles own drill press (screw jack) for changing tires. I still need to test fully loaded and with all three plates in place. 560864


Comments
So far so good, I added the third plate and with grease and the air bags I can get it engaged. I also added one leaf Super Spring and VR front coils for a 3500 clone effect. I deflate the ait bags after I engage the overloads as they are too spongy. Fully loaded with built in generator and 46 gallons of water it sits about one inch higher in the back.

I ordered the upper and lower Torklift overload spring kits for a 2015 Ford Super Duty F-350. The uppers are easy and simple to install. The lowers, require minimal assembly and took less than an hour to install. The lower overload springs on my truck were pre-drilled in the exact place I needed them to be, from the factory, how lucky could I get!!! The uppers are a little above the spring, probably due to the lowers raising the truck 1 1/2 inches. Shipping was fast and the boxes came in great shape, and complete. My only gripe would be the price, the two upgrades are not cheap but work great, so if you need them, bite it and get them both. 290707

Review from a similar StableLoad in Vehicle Suspension


This is the best towing improvement item I have ever purchased. We purchased a new 2018 Ford F-250 super-crew with the 6.2 gas and had our load leveling, anti-sway hitch professionally installed to tow our 2016 28' travel trailer. We towed the trailer for 1550 miles on numerous trips and it was very uncomfortable. At first I thought it was trailer sway, but soon realized it was the truck trying to point left or right or bouncing up and down every time we hit a dip or bump in the road, no matter how slight. It was truly white knuckle driving. I searched for the problem and solutions and decided to try the TorkLift StableLoad system. It was one of the best decisions I have ever made. We could tell within a few blocks from home the truck felt much more stable and on the highway it was like a different truck and trailer. We just towed the trailer 856 miles and it was an incredibly easy and relaxing drive. I love that I can engage or disengage the devices so we don't have a stiff ride when not towing. If I ever install one again I will have someone else drill the spring leafs or at least rent the tool from the manufacturer. I ruined the 2 drills they sent almost immediately by not using enough pressure and using too much drill speed. Once I realized what I was doing wrong I was able to drill the holes using a floor jack to apply pressure as others have described and drilling at the slowest speed possible. Once the holes were drilled it was very easy to assemble and install the StableLoads. 558941
