Good to know before you book
Wheels and tyres
The 3.65T and 3.85T packages work with standard tyre sizes. The 4.2T packages need wheels and tyres rated to at least 1,240 kg each and allow up to 35x12.5R18 pre-rego. The 4.49T needs 1,350 kg.
We'll quote load-rated wheels and tyres on the same job if you need them.
TSA or America's Garage?
TSA covers every rating up to 4.49 tonnes and lets you pick your shocks, and it's the sharper price at 3.85 and 4.2 tonnes. America's Garage is the Fox and BDS option, with a 2 inch lift built in.
Not sure? Tell us what the truck carries and tows and we'll recommend one.
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
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
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
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
Drive away sorted
You leave with the certification paperwork and an alignment set for the new ride height and load.
Chevrolet Silverado 1500 GVM upgrade FAQs
Which supplier should I pick?
Both are federally approved packages fitted the same way. TSA offers every rating up to 4.49 tonnes and a choice of shocks, from the value MXP up to Apex remote reservoirs. America’s Garage is the premium option, with Fox shocks, BDS upper control arms. 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
Is there a difference between the LTZ and ZR2?
Yes. The ZR2 has lower towing and GCM figures from the factory, so its upgraded figures are lower too. Each package shows both where they differ.
Does a GVM upgrade increase towing capacity?
No. It raises how much the truck can carry. Braked towing stays at 4,500 kg for the LTZ and 4,200 kg for the ZR2.
Do I need new wheels and tyres?
Only for the 4.2T and 4.49T packages, which need load-rated wheels and tyres. We'll check what you have and quote options if needed.
