Anti-Jackknife Technology
adding a small device to trailers is all it takes to —
Eliminate Jackknife Accidents for
Semi-Trailer Coupled Vehicles
Save Thousands of Lives
per Year
Reduce Economic Impacts
for All Motorists
NO JACK Jackknife Prevention Systems deliver advanced safety by preventing excessive rotational movement between semi-tractors and trailers during forward motion. NO JACK activates based on vehicle speed and ABS deployment, keeping rotations within recoverable limits.

WHAT IS IT?
Integrated directly into OEM trailer frames, NO JACK features a fully automated pneumatic steel retention pin which engages the "V" throat of the fifth-wheel coupling, locking the connection and ensuring secure cargo transport regardless of weather or road conditions.
WHY?
With NO JACK, fleets benefit from increased safety, reduced insurance costs, and enhanced appeal to safety-conscious public roadway users. Implementation of jackknife prevention systems will save thousands of lives each year.
HOW?
NO JACK fits seamlessly between trailer frame rails, below the cargo floor, and affixed to the apron plate. NO JACK allows for full trailer articulation at low forward speeds and in reverse.
Is NO JACK compatible with existing hardware?
The kingpin and fifth-wheel coupling system is the global standard for connecting trailers, offering a proven, safe, and reliable design for most payloads. NO JACK seamlessly integrates with existing American and European fifth-wheel hardware, ensuring compatibility and readiness for the future of carrier transit.

Articulation Limits
NO JACK offers adjustable positioning within the fifth-wheel throat depending on customer need and preference. The allowable rotation may be set from 10 to 15 degrees, within recoverable limits per FMCSA safety guidelines.
When NO JACK is engaged, can trucks
still use the road?
NO JACK provides sufficient rotational flexibility to allow semi-trailer vehicles to safely navigate lane changes, tight exit ramps, and complex cloverleaf interchanges, while maintaining optimal safety during emergency maneuvers.
Practical APPLICATIONS
Redundant Safety
NO Driver Interaction
NO JACK brings intelligence to trailers by autonomously responding to speed and detecting ABS deployment with no driver interaction required.
The NO JACK system operates independently of the connected truck and uses a wheel sensor to determine the trailer speed and ABS deployment. No other data connections are required.
Loss of Air Pressure
In the unlikely event of air pressure loss, NO JACK safely and gradually disengages while the trailer brakes automatically activate.
Loss of Power
In the unlikely event of power loss to the trailer, NO JACK gradually disengages while the trailer brakes automatically activate.
As the industry shifts toward automated hauling, trailer safety remains paramount. Slick conditions, roadside hazards, and unforeseen scenarios can challenge even the most advanced automated trucking systems, putting bystanders and property at risk. NO JACK safeguards roadways by ensuring secure loads on autonomous haulers, paving the way for a safer transition to a driverless future.
Autonomous Hauling
How is NO JACK Made?
The NO JACK retention pin is crafted from the same material as the kingpin, AISI 8630H Alloy Steel. With an ultimate tensile strength of 150,000 PSI and a yield strength of 115,000 PSI, NO JACK is engineered to recover the heaviest and most delicate payloads safely under any environmental or transit conditions.
The unit’s body is constructed from high-tensile-strength steel, securely affixed to the apron plate, and delivered to trailer manufacturers for integration during assembly.
Compact and efficient, NO JACK weighs 35 pounds.
