The IRONMAN 4X4 GVM Upgrade for the Toyota HiLux N90 2026+ has been engineered to restore payload lost to accessories and increase the vehicle's legal carrying capacity to 3,500kg GVM, allowing owners to safely carry the equipment their vehicle was built for.
This upgrade supports the growing demand from touring, trade and fleet vehicles that regularly operate close to, or beyond factory payload limits.
How Much Payload Can a GVM Upgrade Recover for the 2026 HiLux?
| Standard Toyota HiLux | With IRONMAN 4X4 GVM Upgrade | |
| Gross Vehicle Mass | 3,065–3,120kg | 3,500kg |
| Typical Payload | 778-1,235kg | 1,158-1,670kg |
| Payload Recovered | +380kg to +435kg |
What Does +380–435kg of Recovered Payload Actually Mean?
In practical terms, a GVM upgrade for the HiLux gives you the capacity equivalent of:
- 4–5 additional adults
- A full touring setup - canopy, drawers and fridge without exceeding limits
- Trade tools and equipment carried legally and safely
Where Did the Payload Go? Understanding Accessory Weight
Many of the most popular HiLux accessories carry a significant weight penalty. Below is a guide to typical accessory weights and how quickly they add up on a standard build.
Typical Accessory Weights - Toyota HiLux 2026+
| Accessory | Typical Weight |
| Bull Bar (Aluminium) | + 40kg |
| Bull Bar (Steel) | + 80kg |
| Winch (Synthetic Rope) | + 28kg |
| Winch (Steel Cable) | + 45kg |
| Side Steps | + 35kg |
| Canopy (Fibreglass) | + 100kg |
| Canopy (Aluminium) | + 75kg |
| Drawer System | + 75-90kg |
| Fridge & Slide | + 30-60kg |
| Long Range Fuel Tank (incl. fuel) | + 90kg |
| Water Tank | + 70-100kg |
| Roof Rack | + 25-45kg |
| Rooftop Tent | + 65-115kg |
| Dual Battery System | + 25-35kg |
| Tool Box | + 100kg |
| Rear Bar | + 60kg |
| Luggage | + 100-300kg |
| Passenger (average) | + 80kg |
| Tow Ball Weight | + 100-300kg |
| Tray (Aluminium) | - 150kg |
| Tray (Steel) | + 400kg |
Total accessory weight on a typical build can easily exceed 300–400kg before passengers, tools or camping gear are added. This is why so many accessory-equipped HiLux vehicles operate right at or beyond their factory payload limits.
Real-World Payload Example - Typical N90 HiLux Touring Build
Here's how quickly payload disappears on a fully kitted touring N90 HiLux, starting from an approximate factory payload of 1,000kg.
| Item | Weight | Remaining Payload |
| Starting Payload | - | 1,000kg |
| Bull Bar (Steel) | - 80kg | 920kg |
| Winch (Steel Cable) | - 45kg | 875kg |
| Side Steps | - 35kg | 840kg |
| Canopy (Aluminium) | - 75kg | 765kg |
| Drawer System | - 80kg | 685kg |
| Fridge & Slide | - 60kg | 625kg |
| Long Range Fuel Tank (incl. fuel) | - 90kg | 535kg |
| Roof Rack | - 30kg | 505kg |
| Dual Battery System | - 30kg | 475kg |
| 2 Passengers | - 160kg | 315kg |
| Camping Gear / Tools | - 250kg | ~65kg remaining |
With only ~65kg remaining, there's virtually no margin left for water, recovery gear, or extra luggage - and the vehicle may already be operating outside legal limits.
With the IRONMAN 4X4 HiLux GVM Upgrade
- Upgraded Payload Capacity: ~1,400kg
- Remaining Payload (same build): ~465kg
A GVM upgrade for the 2026 HiLux restores a genuine safe operating margin for equipment, passengers and touring gear without compromising legal compliance.
Improved Axle Load Capacity
Payload isn't the only concern. Accessory-equipped vehicles can quickly approach or exceed factory axle load limits.
The IRONMAN 4X4 HiLux GVM Upgrade increases axle capacity across both front and rear:
