Mitsubishi Triton towing capacity

A useful rear axle rating, with other limits to check

The 26MY 4WD Triton has a 2,040 kg maximum rear axle load. That is useful capacity when the tub carries a canopy and tools, but it is only one limit. The relevant Ford Ranger and Toyota HiLux variants have their own axle ratings and starting weights, so compare the actual configurations rather than assuming a class-wide winner.

This matters because the rear axle is where a tow ball lands. Hitch a heavy van and the coupling load presses down behind the rear wheels, levering extra weight onto that axle while it lifts a little off the front. A higher rear-axle rating means more of that downward load before you run out of plate. On the number that counts for ball mass, the Triton starts ahead of the utes it is usually cross-shopped against.

A strong axle does not raise the whole vehicle or combination limit. A working Triton can still use much of its available carrying capacity before the holiday load goes in.

The combined limit that lands 450 kg short

The standard 26MY GLS 4WD pickup has a 3,200 kg GVM and a 6,250 kg GCM. For a 3,500 kg loaded trailer, the combined limit leaves 2,750 kg for the ute before the towball load is added. This unhitched basis matters: the trailer’s full ATM already includes the ball.

With a 350 kg towball load, that 2,750 kg unhitched ute becomes a 3,100 kg hitched vehicle. It is 100 kg below the standard 3,200 kg GVM. Adding a hitched vehicle mass to full trailer ATM without subtracting the ball would count that load twice.

The comparison with the Ford Ranger, Toyota HiLux and the wider towing-capacity guides needs the same weight basis. GCM limits the whole combination. GVM limits the vehicle with the hitch load aboard. Axle ratings limit where that weight can sit.

Where the 350 kg ball goes after that

The standard 26MY GLS 4WD pickup weighs 2,129 kg at kerb. Its 3,200 kg GVM therefore leaves 1,071 kg before accessories, people and towball load. In an illustrative 350 kg ball case, the GVM allowance for other loads is 721 kg. With a trailer actually loaded to 3,500 kg, the GCM check is tighter: 6,250 minus 3,500 minus 2,129 leaves 621 kg. The ball is already part of that trailer ATM and is not subtracted again from the GCM allowance.

The 26MY 4WD GSR pickup is 2,170 kg at kerb, while the GLX automatic pickup is 2,117 kg. Under the same 3,500 kg trailer and 350 kg ball assumptions, the standard GSR has 580 kg left above kerb and the GLX has 633 kg. Cab-chassis weights do not include a fitted tray, and the GLS and GSR lower-GVM options need their own calculation.

Those remaining figures describe standard vehicles. A canopy, tray accessories, tools and added fuel capacity consume some of the allowance before you pack. If a measured starting weight already includes them, use that baseline rather than adding them again.

Why the back end still sags with a strong axle

Here is the part that confuses owners. The axle is rated to 2,040 kg, so why does the Triton drop its tail under a heavy van? Because the axle rating and the spring tune are two different things. On the GLS and GSR, the rear sits on light-duty leaf springs, and a leaf spring's job is to control ride height, not just to survive a load. The plate can be happy while the spring still squats.

The reviewer evidence is consistent across three independent sources. A caravancampingsales tow test with a 3,100 kg van and 282 kg on the ball measured the front rising about 10 mm and the rear drooping around 30 mm, which the tester described as about the limit before you reach for a load-leveller. A long-term GSR sank rapidly under a loaded tray, with the nose pointing skyward and the steering going light enough that the reviewer felt bullied by the caravan. A long-term GLS reported a ride that was grounded and stable when laden but bouncy to the point of jarring when empty.

So the spring feel runs out before the axle number does. That gap (strong plate, soft spring) is exactly why Triton owners reach for a weight-distribution hitch or airbags long before the axle is anywhere near 2,040 kg. What restores composure is putting the sagged load back where it belongs, set from measured axle weights rather than from how level the ute looks parked.

Setting a weight-distribution hitch on a Triton

The job of a weight-distribution hitch on this ute is specific: take some of the load the rear springs are sagging under and hand it back, partly to the front axle and partly to the van's own axles. When the rear droops 30 mm and the nose lifts 10 mm, the front tyres carry less, the steering goes light and the headlights aim at the trees. Spring-bar tension pulls the rig back toward level and returns weight to the steer axle, where you want it for control.

A weight-distribution hitch redistributes load across the axles; it does not reduce the combination’s total mass or increase a rating. Where its use is permitted, follow the vehicle, trailer and hitch instructions for the required front-axle restoration. Do not assume that returning exactly to unhitched front-axle weight is the correct setting for every vehicle.

When the rig is right, the Triton tows tidily. A 2025 GSR Special Edition tow test ran a 2.7 tonne van that had been professionally balanced and reported no sway, pitch or porpoising at all: the back end stayed planted. That is the whole point of getting the setup right rather than relying on the axle plate to carry a poorly distributed load.

The transmission on a long climb

The 2.4L bi-turbo makes 150 kW and 470 Nm, which is enough torque for the job; the texture is in the 6-speed auto behind it. Two separate long-term tests found the same trait under load: the gearbox is too keen to hold a shorter gear on a climb and slow to settle, with a sticky three-to-four shift that owners learn to manage. On a long towing hill the consensus is to drop it into manual mode and pick the gear yourself rather than let the auto hunt.

It is a quirk, not a flaw, and it is firmly a towing observation rather than a solo one. Unhitched, the auto is unremarkable. But it is the kind of thing worth knowing before you commit to a heavy van and a hilly route, because a transmission that hunts under load is more tiring over a long day than the raw outputs suggest. The engine has the grunt; the auto just needs a firm hand when the road goes up.

Two trims, two suspension stories

The rear-suspension behaviour splits by variant, and the split is worth understanding before you buy. The GLS and GSR run the light-duty leaf springs that sag under ball weight and ride well once laden but feel jarring empty. The cab-chassis and work-focused variants run heavier-duty springs that resist the sag but bounce more when the tray is light. Neither is wrong; they are tuned for different loads.

For a touring buyer, suspension behaviour is something to assess with the actual loads and towing equipment fitted. A work-focused variant and a GLS or GSR may have different spring tuning. Follow the relevant towing instructions and use axle weights to understand the effect of the load; do not treat a particular hitch as universally required.

What the Triton sensibly tows

Put the numbers together and a comfortable touring band falls out around 2,400-2,900 kg ATM. In that range a typical van puts roughly 240-290 kg on the ball, which leaves rear-axle and payload headroom for a canopy, a fridge, two adults and water without spending every kilogram. The combined mass stays clear of the 6,250 kg ceiling with margin to spare, and the light-duty springs, with a WDH set, keep their composure.

Push toward 3,000-3,200 kg ATM and the Triton can still do it, but every choice tightens. A 320 kg ball, a heavy alloy canopy and a drawer system can have the rear axle and the GCM both close before the family is aboard. This is the range where weights stop being admin and become part of the buying decision: measure the loaded ute, measure the van, and confirm the combination on a weighbridge before you sign for either.

A heavily fitted-out Triton and a heavy caravan can use the available capacity quickly. The GSR Special Edition test cited here described one particular 2.7-tonne pairing, not a universal ceiling for every Triton. Compare your own loaded masses, towball load and axle weights before choosing either a different van or another vehicle.

A used-buyer note on older Tritons

If you are shopping used, the line in the sand is February 2024. Everything above describes the current 6th-generation Triton. The previous 5th-generation MR, sold up to 2023, towed 3,100 kg on a different chassis with a 2.4L single-turbo making 133 kW and 430 Nm, and it ran a lower combined limit. Do not carry any of the current numbers back to it.

The older generation also has its own due-diligence item: the intercooler-hose split that shows up in owner reports is a pre-2024 issue, not a current-gen pattern, so weight it when you inspect an MR but leave it out of the conversation on a 6th-gen car. On the current Triton, the live items to know are the disable-each-drive driver-monitoring system, which a 2024 software update scaled back but did not eliminate, and a head unit that some owners report glitching. None of those touch the towing maths; they are cabin character, dated to the 2026 reviews.

Reading the picture from measured weights, not the plate

Everything above turns on one soft spot: the light-duty leaf springs let the rear sag before the 2,040 kg axle plate is anywhere near full, so the way the Triton sits tells you almost nothing about where its real margins are. The plate says you have room. The springs say you are squatting. Only a measured weight settles which is true. The canopy, tools and camping gear all need to fit inside the limits even when the springs tell a different story. Get the loadmate app to use those measured weights as your baseline and see how each recorded change affects the Triton's remaining margins.

Log the weighbridge or mobile-weigher result in loadmate to give your Triton a measured starting point. Include the front axle, rear axle and combination figures from the actual setup. When you later add a tool, move camping gear or change the van’s load, record that change against the baseline. This helps you see which limit needs attention and when another weigh-in would be useful.
