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.

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 Satisfaction 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.

The ride is smooth and the truck handles very well.
Review by
Adding the Torklift stable load suspension really helped my truck from sagging when I load up the in-bed camper. 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.995161
Quality
Immediately corrected the steering problems and distributed the load evenly
Review by
Installed the torklift stable load suspension kit on my Ford F-150. Was very easy to do following the instructions included or directly from the website. Once installed solved all of my suspensions sway by lifting the load and putting more weight on the front wheels. Immediately corrected the steering problems and distributed the load evenly so the truck was level. They are also very easy to engage or disengage from the leaf springs. No more airbags, or air shocks for me.
Quality
Installed them today. They gave my hitch 2.5 inch lift after installing the camper in the bed.
Review by
Dropped airbag pressure from 30 to 10 pounds. Instructions were pretty straight forward. I would recommend these for anyone hauling a camper or heavy load.
Quality
I my opinion they provide firmer support, stability and less sway than airbags
Review by
I my opinion they provide firmer support, stability and less sway than airbags as they use the factory suspension more effectively. I’ve been using airbags for the last seven years and I am kicking myself for not using these sooner!
Quality
Easy installation, progress and easy to understand instructions.
Review by
The assembly was actually very enjoyable kind of like putting together a puzzle when you were a kid I had intended on using the upper stabilizers, but after the installation of the lowers, they worked so well the uppers would not be needed Strongly recommend this product
Quality
made a substantial difference in the headlight aim and vehicle stability.
Review by
Product was moderately easy to install and fit as prescribed. First time we Loaded our camper it made a substantial difference in the headlight aim and vehicle stability. This is a great upgrade that allows the truck to run level when the camper is loaded.
Quality
Great product. Excellent quality.
Review by
I would like to have one unit pre-built (put together) for ease of building the other 3. Took longer to put together and configure than to install!
