Twin 79 Builds

Two Masterpeices in 4×4 Engineering

Building the dream 4×4 is 100% unique to everyone. Every client has different story, different background, different goals and ambitions. Two brothers with passions for off-grid touring, ute musters, and the expansive Australian wilderness, came to us with a vision. After months of detailed collaboration, we were thrilled to unveil their custom 4×4 builds, each uniquely tailored to reflect their adventurous spirits and distinct backgrounds.

The Build Rundown

JMACX 4495 GVM

As a certified JMACX dealer and installer, we began with the JMACX 4495 GVM Upgrade. This upgrade requires a precisely cut and extend the rear chassis, reinforcing it with additional bracing to support a 4495kg GVM. We also completed a full coil conversion on the rear end. The 79 Series serves as an excellent foundation—essentially a blank canvas. Adding a chassis extension, GVM upgrade, and coil conversion significantly enhances its off-road and touring capabilities, readying it for any adventure.
