The team

4WDers, through and through.

The crew · North Lakes, Queensland

Our head technician is an experienced buggy and off‑road racing mechanic, and the crew around him live and breathe 4WDing: they tow, camp and test their own rigs all over the country.

So your 4WD is looked after by people who drive theirs the way you drive yours. The team is headed by Barney Lewis, the hands‑on director behind Legendex.

    We go above and beyond the log book: every item on it, and more, so your new‑car warranty stays intact.

  • We build modified rigs

    The same crew builds modified 4WDs from the ground up, so a lift, a GVM upgrade or a tune is familiar ground.

    Questions after you drive away go straight to the crew who did the work, and the chat on our website answers any time.

  • Leading brands

    Ryco filters, DBA brakes, Dobinsons suspension and Raslarr bars, all fitted in our own workshop.

  • Backed by over 50 years

    More than half a century in performance and 4WDing stands behind every service, and behind the bull bars, rock sliders and Big Boy exhausts we engineer in Queensland.

Questions

Asked before you book.

What people ask the workshop before they book a service.

Is the dyno health check free with a major service?

Yes, while the offer runs. On its own, or with any other job, the dyno health check is $650.

Will a Legendex service void my new‑car warranty?

No. We go above and beyond the manufacturer's log book: every item on it, and more, so your new‑car warranty stays intact.

Can you service and repair my older 4WD?

Yes. We look after new and classic 4WDs, from a general service to major mechanical repairs.

Can I get a pre-trip inspection?

Yes. Before the Cape, the Simpson or the Gibb we check the fluids, bushes, bearings and recovery points, and when you are home we service it after the trip.

What is an ECU remap, and how does it help?

A remap rewrites the tables your engine's computer runs on (injection timing, fuel delivery, boost control and the torque limiters) for more power and torque, so you are off the throttle sooner and towing and overtaking get easier. The Custom Dyno Tune.

Is a remap right for every 4WD?

It depends on the engine, its condition and what is already fitted, so the best answer comes from a technician. Send the form or call, and we will tell you what yours would make. What our tuning has measured.
