Midway through constructing an extreme desert runner, the vision for a Nissan Frontier was drastically altered, necessitating the creation of a bespoke suspension system that defies ordinary logic but performs flawlessly.
The entire process was showcased on the YouTube channel Wheel Every Weekend, which features the build of a 2012 Nissan Frontier destined to tackle desert terrains. After initially aiming for a spring-under leaf spring setup with a flatbed, the client changed course, requesting an exo-cage. This shift in plans forced the designers to reevaluate the packing and led them to completely reimagine the truck’s rear suspension.
The decision was made to adopt a four-link trailing arm setup with the original plan of utilizing a Panhard rod for axle positioning. However, the Panhard rod introduced the issue of tire rubbing against the frame during substantial articulation due to excessive lateral movement. The team then turned to a more complex but effective option: an ingeniously engineered Watts link setup.
Such mechanisms are not unheard of in the suspension systems of certain stock off-roaders like the Ford Ranger Raptor. The prime focus of this system is to restrict lateral movement of the axle while allowing vertical motion, which is essential for maintaining stability during high-speed turns and when landing jumps in off-road scenarios. What sets this Watts link apart is its lateral mount and the fact that it was built following the advice of a trophy truck racer. The result is an overengineered solution without the lateral motion restrictions of a Panhard rod, enabling up to 27 inches of suspension travel!
To do justice to the intricacy of this custom build and the unique components involved, it’s best to hear the explanation directly from the builder. Even for those well-versed in mechanics, the complexity may be challenging to follow—but that’s what makes the expertise of the craftsmen so invaluable.

FAQ Section
What modifications were made to the Nissan Frontier’s suspension?
The Nissan Frontier’s rear suspension was custom-built with a four-link trailing arm design and a uniquely mounted Watts link mechanism to prevent lateral movement of the axle while allowing substantial vertical travel.
Why was a Watts link chosen over a Panhard rod?
The Panhard rod introduced potential tire rub against the frame during extreme articulation. The Watts link provided a solution by minimizing lateral movement without restricting the desired suspension travel.
How much travel does the custom suspension allow?
The custom-built suspension system for the Nissan Frontier allows for up to 27 inches of vertical axle travel.
Where can I see this build process?
The build process was documented on the YouTube channel Wheel Every Weekend, offering viewers a detailed look at the construction and engineering behind this custom suspension system.
Conclusion
Utilizing innovative engineering and no small amount of ingenuity, this custom suspension setup crafted for the Nissan Frontier off-road machine demonstrates the heights of automotive craftsmanship. While the technical aspects of this build may be complex, the outcome is a desert runner ready to face the most challenging terrains while offering an unprecedented level of travel and stabilization. Whether for enthusiasts or professionals, this case study stands as a testament to the creativity and problem-solving skills present in the world of custom vehicle modifications.
