The TRAC System™ is a structural mounting system for rear-door carriers.

It uses bolt-on panel-gap brackets that pick up the factory hinge bolt holes, combined with profile-matched stiffener brackets welded to the carrier.

Together, they create a reinforced hinge-side structure and a controlled, stable way to manage dynamic forces allowing you to carry heavy loads with confidence.

  • protects the latch side from impact and fatigue
  • Distributes slam forces to the strongest sections
  • support heavy loads without stressing the door
  • counters twisting and oscillation

FREQUENTLY ASKED QUESTIONS

How is the TRAC System™ different from basic panel-gap brackets?

Panel-gap brackets combined with profile-matched stiffener brackets work together to establish a controlled load path through the door, distributing forces across reinforced structural regions instead of relying on the latchside door skin or panel gap flanges alone. 
Why is it superior to panel-gap brackets alone?

Panel-gap brackets alone do not stiffen the hinge-side flange, don’t set the load path, and don’t protect the latch-side skin.

The TRAC System™ adds stiffening, controlled geometry, preload, torsional resistance, and balanced load distribution, making the entire carrier-door interface far stronger and safer.
If the Contour brackets press against the door, could this scratch my door during installation?

All three brackets that align to the contour of the van have a rubber pads adeared to the surfaces that make contact with the door surface that prevent scratching during installation.
Do I need to drill into my van to install the TRAC?

The system is designed for a no-drill installation across all primary mounting points. Only one precision hole is required through the latch-side skin; this point is fully integrated into and protected by the TRAC load-path solution to prevent skin deformation.
Is the TRAC System™ patented?

The TRAC System™ is a patent pending load path structural mounting solution involving unique stiffener geometry, contact sequencing, and latch-side preload mechanics.

While panel-gap brackets alone are prior art, the integrated TRAC architecture is novel. The system is currently patent pending No. GB2600961.3”
