Ford - StableLoad Lower Overload – F7859s

IN STOCK

The StableLoad® suspension enhancement manufactured out of stainless steel dramatically improves vehicle handling characteristics by "pre-activating" the stabilizing effect designed for rear springs by keeping them actively under load the way your vehicle factory engineers designed them to operate. It’s also the only suspension enhancement that you can turn on and off with the lower leaf spring design so you can return to your factory ride when not towing or hauling.

The lower quick-disconnect StableLoad® is now available in stainless steel! The new stainless steel StableLoad® are built for tough conditions. Our engineers developed these ultra high performance suspension enhancements to handle the toughest climates and terrain.

Description / Ford - StableLoad Lower Overload – F7859s

Struggling with truck sag, bed squat, side-to-side sway, and body roll? Discover the ultimate solution for your suspension needs in our exciting video. Watch as we put the most popular upgrades to the test, only to find that nothing can match the incredible performance of the StableLoad Suspension Upgrade.

How does the stainless steel lower StableLoad® work? Once you begin to tow or haul with your truck, pressure is applied on the factory overload springs of your vehicle’s suspension. The leaf springs on your vehicle are designed as a spring pack with upper and lower overload leaf springs. When the vehicle is loaded the spring pack engages. The problem is that there isn’t enough stability to support the load, resulting in poor handling characteristics. Here’s just a few you may have experienced:

  • Side-to-side sway
  • Body Roll
  • Porpoising
  • Truck Sag

StableLoad® Features

  • The StableLoad® is the only overload suspension system that follows the two major truck manufacturing laws of suspension:
    Law 1: Must be uncompromisingly comfortable as a passenger vehicle
    Law 2: Must ride safely without compromising comfort while towing and hauling
  • Dramatically improves safety, handling, body roll and porpoising while towing and hauling
  • Ability to turn on and off in seconds
  • Universal fit for all vehicles with factory installed upper or lower overloads
  • Quad contact design complements the vehicle’s specially engineered suspension that automotive manufacturers have invested millions of dollars designing, while all other rear suspension products reduce contact to only two points  
  • Quick no-drill installation
  • Enhances airbag performance by lowering airbag overload air pressure and activating the factory overloads
  • Kit includes four StableLoad® (outfits one complete vehicle)
  • Legendary Lifetime Warranty includes coverage for the vehicle factory leaf springs
  • Proudly made in the USA
  • Recommended for Safety: When hauling a truck camper, Torklift strongly recommends StableLoad to help support the load, reduce sway and body roll, and promote safer, more controlled handling on the road.
  • Backed by Our 90-Day Guarantee: Experience the difference StableLoads make - improved stability, control, and confidence - completely risk-free. If they don't transform your ride within 90 days, return them for a full refund.

PATENT: Load Stabilizing devices sold under the StableLoad® brand name are covered by one or more U.S. PATENTS and/or pending patent applications.

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.
Review by
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 .

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.

Thank you for package tracking and very quick delivery! I also appreciate the videos provided on your website that help to better explain how the StableLoad system works on the lower overload leaf spring, and how the stack of plates should be setup with t

For a future video idea for the StableLoad product: could you have an an overload spring removed from a vehicle (from a Ford F150 for example), and then show close ups of how the StableLoads should be attached? That would be very helpful for the customer to confirm they have them installed correctly. Just an idea....

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.
Review by
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.

Would totally recommend it.

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

Fantastic.
Review by
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.1

Adding the Tork Lift stable load suspension really helped my truck from sagging when I load up the in-bed camper.
Review by
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.
Quality
The stable loads function as advertised.
Review by
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.
Quality
I my opinion they provide firmer support, stability and less sway than airbags as they use the factory suspension more effectively.
Review by
I’ve been using airbags for the last seven years and I am kicking myself for not using these sooner!
