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.

Significantly reduces sway when slide in camper is on. So good to be able to easily twist the wedge out and improve ride when camper is not on. Installation is challenging when springs need to be drilled as for my installation. I rigged a jack as shown on youtube and did very good on first hole but did not get shut down at the end of it and chipped the first bit(two bits were included.) It was a struggle after that for some reason. Torklift sent 2 more bits when I called for advice but the solution for me was learning to sharpen bits on you tube. When the bits quit cutting I would crawl out and go the grinder. Installed on an 03 Dodge 2500 Diesel.

2004 Dodge Ram Pickup

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.


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.

It made all the difference when towing by providing a level of support that could only be gained by changing to stiffer springs that would hurt the hinder the ride all the time. With the stable load system, I can change from supported ride to a regular factory ride in minutes.




by:

I haven't been able to install it. The shops that are listed to be installers haven't known how to install it or even heard of the product, so it just sits unused.


Comments
You mentioned that you have been unable to have the system installed and I recommend sending an installer the link below on a video install for a 2017 Ford 250. This would be a good guide and may allow them or you to be more comfortable with the system.

2018 Ford F-250 Super Duty

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.

They’ve done great holding up my camper and ATV trailer. No need for air bags.

2002 Dodge Ram Pickup

At first I was a little skeptical on buying these for my 2002 Ram 3500 rattle box with airbags and other enhancements added to stabilize my truck. My camper is a Lance 1161 weighing close to 5000lbs,also included bouncing and swaying all over the road on certain road conditions. Well the ride changed to more of a solid carry and it took my death grip off the wheel when approaching road imperfections and running with cross winds. I am very happy with this Stableload addition. The price is a little high but boy what a better ride.

2013 Dodge Ram Pickup

Used these on a 2013 Ram one ton dually hauling a 4500 lb truck camper. Truck also has airbags. Problem I had with the airbags when pressured up the truck would porpoise and had side to side sway.
Install of the stable loads for me was four hours. The leaf spring was extremely hard to drill. I only needed one drill bit to do all four holes. Used a lot of oil. Using a little less pressure in the air bags (10 psi less) the sway and porpoise was greatly reduced. Giving me more security in the vehicle set up. I put these on just before a two week trip. I was so glad I did.


Comments
Following up after a year. Now have a heavier camper. My set up is airbags, stable loads and rear sway bar. Stablloads greatly improved the overall ride quality.

2015 Dodge Ram Pickup

The Lower StableLoads work great on my 2014 RAM 3500 DRW. I use my truck to haul a 2015 Arctic Fox 990 slide-in truck camper. When loaded my truck is right at the GVWR of 14,000#. The Lower StableLoads now allow my truck to ride level where previously the rear of the truck was noticeably lower than the front. Note: the RAM (Dodge) required drilling the lower leaf-springs. TorkLift offers a tool to assist in the drilling of these holes - it was wonderful! If you need to drill your leaf-springs, borrow this tool. Note also: the tool is supposed to come supplied with 4 drill-bits, so you shouldn't need a separate set. I recommend you give TorkLift a call prior to ordering if you need to drill.

2012 Ford F-350 Super Duty

Installed on 2003 F350 long bed with camper package. Drilling springs is challenging. Used a floor jack with a wood block and Milwaukee corded 1/2 drill at low speed and constant pressure with oil. Once drilled parts installed easily. Have driven about 12,000 miles in last year with 3,500 lb dry weight Artic Fox 990 truck camper. Lots of forest service, desert, and logging roads. Running Toyo E range tires. Stabiloaders keep rig level. Very stable on interstate. Would buy again. Torquelift makes fine product in USA.

2019 Ford F-250 Super Duty

Tow a 5TH Wheel to Florida every year from NY. The addition of the TorkLift made a huge difference in ride and braking. Installed on 2019 F250 diesel, even noticed about 2 MPG increase, assume its because of a leveled load. For those DIYers, spend the money and rent the drilling tool and it will save you quite a bit of time and hassle with the install. I watched a video of a person drilling all four holes in about 20 minutes, without the tools you can spend 30 minutes per hole. Love the fact that they can be disengaged when not towing to go back to a stock ride. cheaper and better than air bags and do not have to worry about the popping while driving down the road.

Just finished installing all for torklift stable loads I was hoping it would solve my problem. I have a dodge 2500 diesel with a slide in camper. I’ve installed air bags,rancho 9000 shocks and then a Hellwig stabilizer. Running 80 lbs
But it was still scary driving like you were on balloons and when a big rig goes by sucks truck over ,very unnerving with my family in vehicle. I drove truck with the new torklift stabilizes and dropped ten pounds each test I’m running 40 psi now in bags and I had a smile on my face as it’s so much more stable. I thought truck would sag but it did not very happy I didn’t think it would work Thanks so much by the way,camper loaded is 2950 lbs.

2003 Ford F-250 and F-350 Super Duty

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.

2017 Chevrolet Cobalt

Naturally, the difficult part is drilling the overload springs. They are about 9/16" thick. The picture on eTrailers shows 4 cobalt bits, but came with 2. But, it turned out to be no big deal, since I was able to drill all 4 holes with one bit. I have a slow turning antique 1/2" drill that helped; after drilling 3 holes to dimple (not all the way thru), I didn't have enough arm left to drill the last one, so I employed a floor jack to push up. Worked well. The key is stopping every 5 - 10 seconds and dip the drill tip into motor oil. This works well in lieu of cutting oil. I would make the following changes for a 2017 Super Duty instructions. Drill the hole into the spring 1-1/2" in from the tip instead of 1" per instructions, this is for the rear of the leafs, the front still is at 1". The reason is there is a taper in the thickness near the tip, causing it to not sit firmly onto the spring. I also had to cut 1/2" off of the thin-headed 3/8" bolt for the front of the springs. Even with the rear jacked up and topping out the shocks there wasn't enough space to get it in. The rear worked without cutting. I am going to look for a different clip for the the "stored" pin. I don't think these will stay on. I think instructions could be better, especially in the planning of whether to mount inside or outside the spring stack. But, most of it is okay. I have not tested with the camper, but I am 99% sure it will make hauling the truck camper much better. I tested with temporary felling wedges, so I know it will help a bunch. By the way, I have Torklift tiedowns and Fastguns and love them.




by:

Worth every penny to keep the truck stable. Without the special tool to drill the springs it was an extremely long, tiring process. I place a floor Jack under my drill to increase the pressure on the springs. That helped a lot, but still glad I only had to so it once.




by:
Ford F-350 Super Duty

I installed TorkLifts on my F350 with a Host Mammoth and find I have very little sway even in a heavy crosswind. I highly recommend this product.


Comments
Im very glad I installed the TorkLifts on my 350 Ford. Being top heavy, driving on different road surfaces I know my truck will handle the load without having to worry about it.

Dodge Ram Pickup

After a year on the road with the lowers installed carrying a Lance 1172 (aka Heavy), they have made the biggest impact in ride and handling this Ram 3500 dually. Sway diminished significantly and highway handling improved significantly. Turning street corners no longer feels mushy or soft. If you haul heavy loads in your truck, the Lower StableLoad is worthy of your consideration.




by:
2008 Dodge Ram Pickup

Definitely cut down on the sway on my 08 ram 2500 diesel truck when I have my Lance truck camper loaded. I had to drill my springs. Contacted Torque lift and they sent me a portable drill press and bits. Awesome.

2004 Nissan Xterra

The TorqLink load stabilizers I installed enabled me to carry a dual sport motorcycle on a hitch hauler with no problems on my 2004 Nissan Xterra. The vehicle drove almost like it was unloaded. I did have to remove the rear sway bar to fit the back load stabilizers, but the sway bar has little value anyway. I recommend this product.

This kit will only fit models with the upper overload spring. Therefore no, they will not work on your 2004 Ford F-150. Instead you will need to use the TorkLift kit designed for lower overload springs such as the TorkLift StableLoad Rear Suspension Upgrade...

  • TorkLift StableLoad Suspension Enhancement Recommendation for a 2007 Dodge Ram 2500
    The part number that is compatible with your old 2002 Chevy Silverado would have been the part # # TLA7310. Whereas the confirmed part number for your 2007 Dodge Ram is the # TLA7311 that you referenced.

  • Does installing the TorkLift StableLoad Rear Suspension Upgrade Void the Factory Warranty?
    According to the (15 U.S.C. § 230) Magnuson-Moss Waranty Act, no one thing would void the entire warranty on a vehicle. If it were proven that this one item cause a specific damage then they could deny a claim related to that one part.

Both TorkLift # TLA7310 and # TLA7311 are a confirmed fit for your F250. The 7310 is for leaf springs that are already...

  • Suspension Enhancement for Lowered 2007 Toyota Tacoma
    Yes; the best option - so long as your 2007 Tacoma has factory leaf springs and a lower overload spring - is the TorkLift StableLoad Suspension Upgrade # TLA7311S. These are compatible with lowered trucks, and work by bolting onto the ends of each overload spring on your Tacoma, and essentially "activate" it early by filling in the gap between your leaf springs and the overload spring.
