The StableLoad® 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.
StableLoads are designed to improve the handling characteristics of your loaded vehicle by “pre-loading” the factory overload spring.

StableLoad Quick Disconnect (Lower Overload) OVERVIEW
The StableLoad Quick Disconnect (patented) is our number one recommended most effective and versatile StableLoad. This StableLoad design is specifically engineered for the extremely robust lower overload springs. The lower overload springs are generally over 30% stronger than upper overload springs making this StableLoad design the most effective. This StableLoad design offers astounding improvement in safety and vehicle handling and is accomplished by putting the robust lower overload to work sooner dramatically stabilizing the vehicles suspension making the vehicle's passengers and load significantly safer. All StableLoad kits work equally well with or without aftermarket airbags overloads.
The Quick Disconnect models for the lower overload spring incorporate a unique design that allows the StableLoad to quickly engage or disengage your lower overloads, enabling you and your passengers to ride in safety and comfort when towing or hauling and to quickly return to the original ride in just seconds when not towing or hauling. This is accomplished by attaching each of the StableLoads (four per kit) onto each overload end (front and rear passenger side, front and rear driver side). The Quick Disconnect StableLoad Series is designed with a tapered wedge mounted to a hinge mechanism that allows the StableLoad to be hinged in or out of engagement in seconds using a common 3/8" ratchet extension and ratchet. Each precision crafted StableLoad kit carries our Legendary Lifetime Warranty and is proudly made in the USA.

How to drill a leaf spring in 37 seconds
The key to drilling a leaf spring effectively is to apply a significant amount of force, using a cordless drill with a very slow rotation speed and a well-lubricated drill bit. Using our special StableLoad Leaf Spring Drill Tool, cobalt drill bits and cordless drill, the specifically designed StableLoad Drill Tool cradles the drill allowing you to slowly guide the drill bit with little effort. No need to struggle with keeping the drill in place while applying a significant amount of force by hand -- the StableLoad Drill Tool does the work for you and is the simplest and quickest method to drill the spring. If you have decided you do not want to use the StableLoad Drill Tool, read below.
The StableLoad Drill tool is available to rent for FREE. We require a $150 refundable deposit. Customer pays freight both ways. Tool must be returned within 30 days or deposit is forfeited. Tool comes with 4 extra drill bits. If additional drill bits are needed, we provide them for an additional $10 each.

StableLoad Quick Disconnect (Lower Overload) Part #A7311 (with drill kit)
The StableLoad Quick Disconnect (lower overload) Part #A7311 (with drill kit) is designed as a universal vehicle application for trucks, SUV's, vans, commercial applications and other vehicles equipped with lower overload springs that -- DO NOT -- come already pre-drilled from the vehicle manufacturer (see application guide). The StableLoad Quick Disconnect DRILLING REQUIRED kit (part number A7311) is available for installation with amazing results. This kit comes with two specially treated drill bits and specific instructions for drilling the required (four) 7/16" diameter holes through the ends of the lower overload. The average time to complete the drilling process is approximately 35 minutes. Each precision crafted StableLoad kit carries our Legendary Lifetime Warranty and is proudly made in the USA.

StableLoad Upper Overload Part # A7200/A7202 (No-drill) Overview
StableLoad is engineered for Ford, Dodge and GM trucks fitted with factory upper contact overloads (see application guide). Torklift's StableLoad for upper overload applications is designed to replace the smaller, inefficient factory overload bump stop pads, putting the upper overload springs to work sooner. It dramatically stabilizes the vehicle suspension and makes the vehicle's passengers and load significantly safer.
The StableLoad upper overload is available for a very quick and simple no-drill installation with serious improvement results.
This is accomplished by bolting each of the StableLoads (four per kit) onto each overload frame bump stop pad (front and rear passenger side, front and rear driver side) StableLoad kits work equally well with or without aftermarket airbags overloads. Each precision crafted StableLoad kit carries our Legendary Lifetime Warranty and is proudly made in the USA.

StableLoads on Vehicles with Aftermarket Airbag Overloads
The downside to airbag overloads is they accomplish all this by lifting the weight off the factory-engineered spring suspension. Your vehicle engineers designed the weight to be carried over the progressive 4' rear leaf springs. On any heavy towing or hauling set up, to level the vehicle with airbags means you have to take a majority of the weight off the factory leaf spring suspension and are now carrying that weight on an area roughly equivalent to the size of a two footballs. This is why you can actually experience a considerable increase in unsafe handling such as sway, porpoising (bucking) and body roll even though the vehicle is now closer to level with the airbags engaged.
As stated above, the StableLoad dramatically improves vehicle handling characteristics by "pre-activating" the stabilizing affect designed into the rear springs by keeping the springs actively under load the way your vehicle factory engineers designed them to operate. The StableLoad accomplishes this and functions equally as well when used with or without airbag overloads. For vehicles that do not yet have airbag overloads, we recommend starting with the StableLoad prior to investing in airbags.
