Toyota TundraUp to 3,999 kg GVM

The Tundra tows 4,500 kg, but with only around 700 kg of payload, a couple of passengers and the towball weight of a big van can put it over. Both packages lift payload to 1,249 kg, keep your factory wheels and add a 2 inch lift.

Good to know before you book

Keep your factory wheels

Both packages are approved on the factory wheels and 265/65R20 tyres, rated to 1,075 kg each. No wheel or tyre change needed.

If you do want to change wheels, they need to carry the same load rating. We'll check that for you.

TSA or America's Garage?

Same rating, same towing, same factory wheels. TSA uses Apex shocks and is about $2,700 cheaper. America's Garage uses Fox Elite shocks, BDS upper control arms and Boss Air bags.

Buying new? Talk to us before the vehicle is registered. A pre-rego upgrade usually keeps more of your towing capacity than doing it later.

How a GVM upgrade works with us

One workshop handles the whole job: the kit, the wheels and tyres it needs, the fit and the paperwork.

  1. 1

    Plan the build

    We look at how you load and use the vehicle: people, fuel, water, drawers, canopy, roof gear and towball weight. If you're not sure where you sit, pop in or give us a call and we'll walk you through it.

  2. 2

    Pick the package

    We match the kit to the job and quote the load-rated wheels and tyres it needs at the same time, so there are no surprises.

  3. 3

    Fit and certify

    Fitted in our Brendale workshop with the supplier's engineering. Most fits take 2 to 3 days. Chassis extensions take longer.

  4. 4

    Drive away sorted

    You leave with the certification paperwork and an alignment set for the new ride height and load.

Toyota Tundra GVM upgrade FAQs

Which supplier should I pick?

Both are federally approved pre-rego packages to 3,999 kg, fitted the same way. If you want the most capacity for the money, TSA is hard to beat. If ride quality and the Fox and BDS name matter most, go America's Garage.

Does a GVM upgrade increase towing capacity?

No. Braked towing stays at 4,500 kg. The upgrade gives you payload headroom, so you can load the truck properly while towing.

Do I need new wheels and tyres?

No. Both packages are approved on the factory wheels and 265/65R20 tyres.

Can it be done on a registered Tundra?

Yes, both packages can be arranged post-registration, however there will be an additional engineering fee due to a modification plate being required.

How long will it be off the road?

Most fits take 3 to 5 days. We'll give you a time frame when we quote.
