GWM TANK 400 accessories should be matched to the exact market specification, powertrain, model year and trim, not simply to the TANK 400 name. Petrol, Hi4-T plug-in hybrid and other versions may share much of their body shape, but powertrain packaging, high-voltage components, underbody clearances, sensors, wiring and factory equipment can change what fits and how it must be installed.
Decision Maker 4X4 currently groups its TANK 400 catalogue under Petrol and Hybrid to make browsing easier. Those labels are a starting filter—not proof that every product in a collection fits every vehicle in that group. The individual product, selected variant and written supplier confirmation remain the final references.
Quick answer: do petrol and Hi4-T TANK 400 accessories interchange?
Not automatically. Low-risk cabin items may be shared when the console, trim and controls are identical. Structural, electrical, underbody, suspension, towing and protection accessories need a vehicle-specific check because the Hi4-T adds a traction battery, electric drive hardware, charging equipment and high-voltage systems.
Before ordering, confirm these ten points:
- Country or market specification, VIN/chassis details and right- or left-hand drive.
- Exact powertrain: petrol, Hi4-T, Hi4-Z, diesel or another market version.
- Model year, build date, trim and factory wheel or bumper package.
- Camera, radar, parking-sensor and lighting positions.
- Battery, fuel, exhaust, cooling and service clearances underneath the vehicle.
- Roof mounting system and complete touring load.
- Towbar, recovery-point and trailer-electrical ratings.
- Wheel, tyre, brake, TPMS and suspension compatibility.
- Electrical current draw, connectors, fusing and high-voltage separation.
- Installation method, freight constraints and local modification rules.

1. Identify the vehicle before choosing the product
Start with the information shown on the vehicle and its documents. Record:
- country or market specification;
- model year and build month;
- exact powertrain and badge;
- trim or grade;
- right- or left-hand drive;
- VIN or chassis details when appropriate;
- factory wheel, bumper, roof and side-step equipment; and
- existing accessories or modifications.
This matters because TANK 400 availability differs by country. GWM Global describes Hi4-T as a parallel petrol-electric system with mechanical four-wheel drive, while individual markets publish their own model combinations and specifications. An overseas installation video or product photo may show a vehicle that looks identical but uses a different bumper, sensor package, steering position or underbody arrangement.
Australian reporting in April 2026 said the TANK 400 was under consideration for local release, but had not been confirmed. Until GWM Australia publishes a final local specification, do not treat an overseas part as Australian-market fitment evidence.
2. Treat petrol and Hi4-T as separate fitment branches
A petrol TANK 400 and a Hi4-T may share exterior panels, but the area behind those panels can differ. The Hi4-T architecture combines an engine, electric drive components, a traction battery and charging hardware. Those systems can affect:
- underbody packaging and guard shape;
- cooling airflow and heat management;
- exhaust routing;
- service and emergency-isolation access;
- cable and hose routes;
- available mounting space; and
- front and rear axle loads.
The safe question is not “Does this fit a TANK 400?” It is “Which TANK 400 market version and powertrain was used to develop and test this exact part number?”
If the supplier cannot answer, request unedited installed photos, fitting instructions and a written list of exclusions. Do not use drilling, cutting or cable relocation to force a high-consequence part onto an unverified vehicle.
3. Map cameras, radar, sensors and lighting before fitting front accessories
Bull bars, nudge bars, grille inserts, light mounts and number-plate brackets can sit close to active-safety hardware. Before ordering, photograph the complete front end and identify:
- parking sensors;
- forward and surround-view cameras;
- radar or other driver-assistance sensors;
- headlamps, fog lamps and indicators;
- cooling openings and shutters;
- washer equipment;
- number-plate location; and
- factory recovery or tow points.
A circular hole in a bar is not proof that the original sensor angle, depth and field of view will be preserved. Ask whether the product includes model-specific brackets, whether calibration may be required and whether the fitting instructions retain the camera and radar positions.
After installation, test the parking display, cameras, adaptive-cruise and lane-support functions in a safe environment. Use a qualified workshop if the job affects driver-assistance hardware or structural mounts.
4. Check the complete underside—not only the chassis holes
Underbody guards, rock sliders, auxiliary tanks and exhaust-adjacent parts should be checked against the whole installation area. Matching bolt holes are only one requirement.
For a petrol vehicle, verify clearance around the engine, transmission, transfer case, exhaust, drains and routine service points. For a Hi4-T, also confirm the location and protection requirements of the traction battery, high-voltage cables, electric-drive hardware and associated cooling systems.
Ask the supplier to show:
- the exact powertrain used for development;
- each panel and bracket included in the kit;
- clearances to hot, moving and high-voltage components;
- ventilation, drainage and mud-cleaning provisions;
- access needed for normal servicing; and
- the removal sequence when workshop access is required.
Never drill, probe or attach an earth point near orange high-voltage cables or an unidentified battery enclosure. Hybrid-system work belongs with technicians trained for the vehicle.
5. Build roof and touring systems from the mounting point upward
A roof build is one load system: vehicle mounts, rails, crossbars, platform, brackets and cargo. The lowest applicable limit governs the completed setup.
List the mass of every item, including:
- rack or platform;
- awning and its brackets;
- rooftop tent;
- water or fuel container;
- recovery boards and shovel;
- storage boxes; and
- permanent lighting or wiring.
Then check overall height, side loading, wind exposure, garage clearance and how cargo will be restrained. Products visible in a TANK 400 collection may be universal touring equipment rather than a vehicle-specific mounting kit. A universal awning still needs a rack and brackets approved for the actual load and use.
For Australian use, compare the completed installation with the vehicle manufacturer's limits, the rack manufacturer's instructions and the requirements that apply in the registration jurisdiction.
6. Separate towing, recovery and accessory-mounting functions
A towbar, recovery point and accessory bracket perform different jobs. Do not infer a recovery rating from a strong-looking hook, thick plate or tow receiver.
Before towing, verify:
- the exact vehicle's braked and unbraked towing limits;
- GVM, GCM and axle limits;
- towbar, tongue and towball-download ratings;
- trailer wiring and brake-controller requirements;
- camera, sensor and spare-wheel clearance; and
- the effect of passengers, luggage and accessories on remaining payload.
Before recovery, use only points that the manufacturer or supplier identifies and rates for that purpose. Confirm the direction of pull, compatible shackles or soft shackles and the recovery method. A rear tailgate expansion bracket or roof mount is not a recovery point.
7. Specify suspension, wheels and tyres as one system
Suspension selection should reflect the completed vehicle, not only a desired lift height. Record permanent front, centre, roof and rear accessory mass; normal passenger and cargo load; towing use; and the surfaces the vehicle will encounter.
Petrol and Hi4-T variants can have different kerb mass and axle-load distribution. A spring or damper package advertised for one may not deliver the intended ride height, travel or control on the other.
For wheels and tyres, confirm:
- wheel diameter, width, offset and centre bore;
- load rating and fastener requirements;
- brake and suspension clearance;
- tyre size, load index and speed rating;
- TPMS compatibility; and
- clearance at full steering lock and suspension travel.
After changes, arrange alignment and check headlamp aim, sensor operation, tyre coverage and any certification requirement.
8. Keep accessory wiring separate from high-voltage systems
An auxiliary light, compressor, fridge or radio usually operates from the vehicle's low-voltage electrical system. That does not make every wire or mounting area safe to use.
Prepare a wiring plan covering:
- current draw and duty cycle;
- cable size and route;
- fuse or circuit-breaker location;
- relay or control method;
- approved earth point;
- water, heat and abrasion protection;
- shutdown behaviour; and
- interaction with vehicle networks or software.
On a Hi4-T, the installer must identify and avoid high-voltage components. Do not splice an unknown circuit, pierce a sealed enclosure or assume a convenient bolt is a safe earth. Ask whether the vehicle needs a dedicated interface, coding or post-installation diagnostic check.
9. Check cabin shape, airbags and driver reach
Phone mounts, console brackets, trays, shift-knob covers and storage accessories can look simple but remain trim-specific.
Compare the product with the actual vehicle for:
- left- or right-hand-drive console orientation;
- screen, vent and switch positions;
- gear-selector shape;
- wireless-charging area;
- seat movement and access;
- knee and side-curtain airbag zones;
- driver sightline; and
- sharp edges or loose objects in a crash.
Do not block a vent, screen, warning indicator or emergency control. A mount should remain secure on corrugations without forcing trim clips or placing a device where it obstructs the windscreen.
10. Confirm availability, package contents and freight before paying
Large TANK 400 accessories can involve multiple cartons, long lead times or destination-specific freight. Before checkout, ask the seller to confirm:
- exact product and selected variant;
- current stock status;
- numbered list of parts and fasteners;
- carton count, dimensions and total mass;
- freight cost and delivery restrictions;
- visible-damage inspection process;
- return conditions before installation or painting; and
- installer requirements.
Dry-fit body, underbody and structural parts before paint or permanent modification. Keep packaging until the full kit has been checked against the parts list.
Which TANK 400 accessories are easier to verify?
Removable cabin organisers, protective liners and universal touring tools can be lower-risk starting points when their dimensions and safe placement are clear. They are still not automatically universal.
Higher-consequence categories include:
- front and underbody protection;
- towing and recovery hardware;
- suspension, wheels and tyres;
- roof platforms and rooftop tents;
- auxiliary tanks; and
- high-load or integrated electrical accessories.
For these products, written vehicle-specific evidence and a qualified installer are more valuable than a broad “fits TANK 400” badge.

Frequently asked questions
Do all TANK 400 accessories fit both petrol and Hi4-T models?
No. Some body or cabin parts may be shared, but underbody, electrical, suspension, towing and protection fitment can change with the powertrain and market specification. Confirm the exact part against the exact vehicle.
Is selecting “Hybrid” in a collection enough to prove Hi4-T fitment?
No. It is a catalogue filter. Review the individual product page and obtain written confirmation for the market, model year, powertrain, trim and selected variant.
Is the GWM TANK 400 officially on sale in Australia?
Australian media reported in April 2026 that GWM was developing the business case, but a local launch had not been confirmed at that time. Check GWM Australia's current model list before assuming Australian availability or specification.
Can a workshop drill around the Hi4-T battery to mount a guard?
Not without verified vehicle-specific instructions and appropriate expertise. High-voltage enclosures, cables and cooling systems require trained handling. Do not drill or attach hardware near unidentified hybrid components.
