ABOUT FULLSOOT 4X4
Raising The Standard In Diesel Performance & 4WD Builds
At Fullsoot 4x4, we believe the diesel performance and 4WD industry deserves better.
Too many vehicles are rushed, poorly tuned, badly wired or built with shortcuts — leaving owners disappointed, out of pocket and with unreliable vehicles.
We started Fullsoot 4x4 with a simple vision:
To build vehicles properly and set a new standard in the industry.
Based in Neerabup, Western Australia, Fullsoot 4x4 specialises in premium diesel performance, engine builds, dyno tuning, gearbox upgrades and high-quality 4x4 solutions for owners who want reliability, drivability and real-world performance.
We are passionate about building vehicles that not only perform — but last.
Whether your vehicle is built for:
✔ Touring
✔ Towing
✔ Daily driving
✔ Performance
✔ Serious off-road use
We believe every build should be completed with precision, pride and attention to detail.
Built Properly. Tuned Properly. No Shortcuts.
At Fullsoot, we don’t believe in cowboy workmanship.
We don’t believe in rushed jobs, guesswork tuning or cutting corners to save time.
From engine builds and gearbox upgrades to ECU calibration and wiring — every vehicle is treated with the same level of care we would expect on our own.
Because performance means nothing without reliability.
And reliability comes from doing things properly.
