Tank 300 Tow Bar: Options, Fitment & the Wiring Trap

Which tow bar fits?

Yes, a tank 300 tow bar exists in both genuine and aftermarket form for the GWM Tank 300 built from October 2022 onward — and multiple Australian suppliers stock or ship them nationally.

The genuine GWM tow bar assembly with wiring harness carries a fitted RRP of approximately $1,061 and is sourced through your dealer. Aftermarket options start around $402 for the TAG XR and step up from there depending on features and supplier.

Allin Towbars, Savage Tech Australia, TAG, and Land4x4 all list fitment-specific bars for this vehicle. We cross-check listings against factory mounting points before recommending any option, and build date compatibility — specifically 10/2022-on — is the first thing to confirm on your compliance plate. See our full GWM Tank 300 accessories overview for related fitment items.

Towing capacity: know the numbers

Before selecting any hardware, lock in the factory figures. GWM rates the Tank 300 at 3,000 kg braked towing load, 750 kg unbraked, and a towball download limit of 300 kg — confirmed via the genuine GWM accessories listing.

You may see both 2,500 kg and 3,000 kg quoted, and both are correct depending on build date. GWM upgraded the Tank 300's braked towing rating from 2,500 kg to 3,000 kg for petrol and hybrid models in late May 2025 — earlier builds are rated at 2,500 kg with a 250 kg towball download. Cross-reference your own compliance plate and owner's handbook, since many tow bar listings still show the earlier 2,500 kg figure.

Any tow bar you fit must be rated to at least match these figures. Fitting an underrated bar voids the point of the vehicle's capability and can create insurance exposure.

The more pressing real-world concern is GVM payload. Owners report the Tank 300's payload sits at approximately 450 kg. Add an alloy bullbar, a tow bar, passengers, and gear, and you can breach GVM before the trailer is even hooked up. Factor tow bar weight into your payload budget before purchase — it is a genuine fitment consideration, not a theoretical one.

Genuine vs aftermarket: what's different?

Three categories cover the Australian market for this vehicle: genuine dealer-fitted assemblies, aftermarket bolt-on bars, and removable options.

The genuine GWM tow bar assembly — available through authorised dealers at approximately $1,061 fitted RRP — integrates directly with the vehicle's electronics and is the only confirmed path to activating the factory Tow Mode. It includes a wiring harness matched to the Tank 300's CAN bus architecture. If Tow Mode matters to you, this is the option to price up first.

The TAG XR sits at the opposite end of the price range, starting at around $402. It is built in Australia, engineered for recovery and offroad use as well as towing, and replaces the factory harness rather than working with it. TAG explicitly states the XR does not enable Tow Mode — that needs to be factored into your decision before checkout, not after.

Savage Tech Australia and Allin Towbars both offer fitment-specific bars for the Tank 300, with Allin providing installation in their Adelaide workshop and kit shipping Australia-wide. Land4x4 lists a black powder-coated option suited to buyers who want a straightforward bolt-on. Owner communities also reference the Brink towbar as a well-regarded option, particularly for those intending DIY fitment.

A removable option — noted in owner communities under the Tank Drive name — suits buyers who want to retain the rear bumper aesthetic when not towing. ADR compliance is non-negotiable across all categories; confirm it on the product listing before adding anything to your cart.

The wiring harness trap

The Tank 300 comes with a factory pre-wired plug behind the rear bumper. That sounds convenient, but it is the source of the most common fitment confusion we see.

Not every aftermarket tow bar kit uses that plug. The TAG XR, for example, replaces the factory harness entirely — it does not tap into the existing plug. Other kits use an adapter that connects to it. These are fundamentally different electrical approaches, and mixing them up creates real problems.

Tow Mode on the Tank 300 — which adjusts throttle response and other parameters for towing — appears to require the genuine GWM wiring solution to activate. Owners fitting aftermarket harnesses report that Tow Mode does not activate regardless of the plug arrangement.

There is a second catch worth knowing: some plug-and-play adapters disengage the vehicle's cruise control whenever the adapter is connected, trailer or not. Verify both points with your supplier before committing to an aftermarket harness.

The harness format also matters for trailer brake controllers.

If you plan to tow a braked load over 750 kg, confirm whether your chosen harness supports a brake controller output.

The Tank 300 ships with a 13-pin European-style factory plug, and most Australian kits include a 13-pin to 7-pin flat adapter. Critically, the factory loom is not compatible with electric trailer brake controllers — if you tow braked loads, you need a separate universal brake-controller loom that bypasses the factory plug. Confirm this before purchase, not on installation day.

DIY or professional fit?

Most bolt-on bars for the Tank 300 are within reach of a competent home mechanic. The Brink towbar is specifically noted by owners as DIY-friendly. Savage Tech Australia publishes a step-by-step harness installation video for the Tank 300, which gives a realistic preview of what the job involves before you commit.

The bar itself typically involves removing the rear bumper trim, locating the factory chassis mounting points, and torquing the bar to spec. The harness is where the complexity increases — particularly around the pre-wired plug situation described above.

Professional fitment is the safer call in three scenarios: you need Tow Mode active, you are fitting the genuine GWM assembly, or your vehicle is still under the manufacturer's warranty and you want to protect it. Incorrect fitment can affect ADR compliance and create insurance complications — that is a practical risk worth naming honestly.

Allin Towbars offers installation with fitted pricing available on request, which suits owners who want a workshop rather than a driveway job. GWM dealer fitted pricing is also available on request.

If your vehicle is loaded with accessories and approaching GVM limits, a professional installer can also flag payload concerns before the bar goes on. For broader accessory planning, our GWM Tank 300 accessories guide covers how to stack fitment decisions without blowing payload.

Checklist before you buy

Run through these before placing an order. Build date: check your compliance plate confirms 10/2022-on — earlier builds are a different vehicle generation and may not share mounting points.

Ball size: 50 mm is standard for Australian towing. Confirm whether your chosen kit includes the ball or requires separate purchase. ADR compliance: required for all tow bars used on Australian roads — confirm it is stated on the product listing.

Payload check: subtract the tow bar's stated weight from your approximate 450 kg GVM payload, alongside any bullbar, roof rack or other accessories already fitted.

Tow Mode: decide before choosing a harness, not after. Trailer brake controller: if towing braked loads above 750 kg, confirm your harness supports one. If you are also running underbody protection, check our GWM Tank 300 bash plate guide — the GWM Tank 300/400 chassis guard plate at $519 adds weight that also comes off your payload budget.

If recovery is part of your use case, the GWM Tank 300 split tow hook with shackle at $165 complements a tow bar setup and is rated for the vehicle's recovery points.

Fitment Check

Confirmed compatible with: GWM Tank 300 (10/2022 - on), Australian market. Check the compliance plate on your vehicle for the build date and confirm 10/2022-on compatibility with your chosen supplier before purchase. Contact us with your VIN to verify against current supplier data before ordering.
