5 fluid checks before any serious trip. 15 minutes at home. Could save your trip.
Engine oil — level + colour. Gritty burnt oil needs changing before you head anywhere remote.
Coolant — check cold, never hot. Brown or rusty = your cooling system is corroding from the inside.
Brake fluid — the most skipped check on this list. Dark brown fluid on a loaded vehicle heading down descents is serious trouble waiting to happen.
Power steering — 30 seconds. Level + look for milky discolouration.
Diff + gearbox oil — front diff, rear diff, transfer case, gearbox. Low or water-contaminated = you won't know until something stops turning in the middle of nowhere.
Part of our weekly pre-trip series. Save this. Send it to your travel mate.

You upgraded your GVM but Did you upgrade your brakes?
Factory brakes are designed for your vehicle at standard kerb weight. GVM lets you carry more. A trailer adds more again. Same brakes, more mass, highway speed. That gap is where people get into serious trouble.
3 upgrades to consider after a GVM upgrade:
Brake pads rated for higher heat thresholds
Braided brake lines that don't expand under pressure
Bigger rotors (in some cases, depending on setup)
Brake fade on a long descent with a loaded van isn't a gradual warning. It happens fast, at the worst possible moment.
The industry talks endlessly about what you can carry. Almost nobody talks about whether you can stop once you're carrying it.
If you've done a GVM upgrade and never had the brake conversation — come see us. Part of our GVM series.

Feedback from 5,000 kilometres of towing. After that many kilometres in a loaded tow rig, three things surface:
1. Fuel economy matters for range, not cost — petrol V8s need bigger tanks for remote touring.
2. Comfort over 8 hours is the real test, not the 30-minute test drive.
3. The build keeps growing. Pick payload headroom for where you're heading, not where you are.

Part 3 of the tow vehicle series. Parts 1 and 2 on the profile.

Rated to tow and set up to tow are two very different things. 👇

Part 2 of our towing series — here's what actually changes between driving it off the lot and being ready for the road.
Suspension first. Factory setup is built for smooth roads and a weekend away. Add a canopy, drawers, fuel, water and a 2,500kg trailer and the rear sags, headlights point at the sky and the vehicle wanders. A kit matched to your loaded weight fixes all of it.
Brakes next — and most people skip this. Factory brakes handle a few hundred kilometres fine. Tow a 3 tonne van down the Great Dividing Range for two hours and you'll feel exactly why this matters. Upgraded pads, a proper electric brake controller and a weight distribution hitch sort it.
Payload last — but price it in early. A GVM upgrade isn't a mod. It's a legal requirement once you've added canopies, drawers, batteries, water tanks and a full tow load. Most touring 300s, RAMs and Patrols end up needing one.
Miss Part 1? It's on the channel. Part 3 coming soon.

$150K of truck doesn't mean it's ready to tour. Here's where to actually spend your money. 👇

But first — check your payload before anything else. The 300 eats it fast. If you're over GVM loaded up for touring, that's a legal issue before it's a capability one. Sort it first.

Then, in order 👇

1️⃣ Suspension — the single biggest improvement for most 300 owners. Factory setup runs out of capability the moment you load it for touring.

2️⃣ Tyres — the factory rubber is the weak link. Maxxis Razr, BFG KO3, Toyo Open Country. Puncture resistance and gravel confidence the 300 should have left the showroom with.

3️⃣ Bull bar and driving lights — animal strikes are real. Night driving fatigue is real. Winch-compatible bar gives you self recovery anywhere.

4️⃣ Dual battery — fridge, lights, devices. Most people don't realise how useful it is until they've got one.

5️⃣ UHF — cheapest mod on the list. Earns its keep on every single trip.

Suspension and tyres alone unlock about half the truck's potential. Everything else builds from there.

Come see us in Brookvale to build yours properly.

$400 to make your 4WD feel 20% quicker off the line.👇

Not a tune. Not extra power. No touching the engine.

A throttle controller removes the built-in pedal delay that every manufacturer adds for fuel economy and smooth take-off. On a heavy 4WD or towing setup that delay feels like hesitation, sluggish take-off and slow gear changes.

The Pedal Torq fixes that. 5 driving modes from Economy to Sport, dash mounted, and it locks the accelerator when parked as an anti-theft measure.

🔥 July only — buy any Torqit exhaust in store or online and we'll throw in the Pedal Torq free. $400 value. All the power!

Four 4WDs. Four builds. Four completely different owners. Which one are you? 👇
🟡 76 Series — returning customer, one of the more capable tourers we've built this year. Final piece going in today. RVSS drawer system, Victron lithium and a Dometic 115L fridge. Done.
🟡 250 Prado — simple weekender. TJM Outback bull bar and Ultima light bar. Frontal protection and lighting sorted in one visit.
🟡 300 Series — luxury tourer that needs to tow for a month. Suspension, wheels and tyres, bull bar and winch on. GME UHF mounted, towing package wired, lithium battery seated. Coming together nicely.
🟡 VW Amarok — HSP electric roller shutter. Lockable, weathertight, keyfob access. Different platform, same thinking.
Four budgets. Four different goals. One workshop.
If yours is next — come see us

Your diesel's intake is slowly choking itself. And you can't see it happening. ⚠️
Blow-by gas carries oil vapour straight back through your intake system every time you drive. Carbon builds. Performance drops. Most people don't find out until something expensive breaks.
A catch can pulls that oil out before it gets back in. Clean air in, longer engine life out.
Come see us in Brookvale before the damage is already done.
