Silverado 2500HD GVM Upgrade
A GMSV Silverado 2500HD arrives at 4,495 kg in NB1, or 5,148 kg if it is already NB2. These federally approved SSM packages take it to 5,500 kg or 6,000 kg. That is NB2, so the driver needs a Light Rigid licence. We fit the package as specified at Arundel or Mackay. Private imports are not covered. A taller lift does not add GVM once the stage is chosen.
Factory combined mass stays 12,474 kg and braked towing stays 4,500 kg on every stage. Payload below uses a 3,762 kg kerb. Your canopy, bar and winch eat into that payload.

What stays in the kit
In the approved package
- The shock and lift combination for that stage
- BDS control arms
- Rear packs, or Kelderman air on 3.5 and 6.5
- Flares where the stage needs them for the tyre
- Install at Arundel or Mackay
Quoted around it
- Load-rated wheels and tyres
- Bull bar, lighting, steps, long-range tank
- Anything that changes kerb weight
We do not swap the shocks, arms or packs for a different brand. That breaks the approval.
State-Based Engineering
A state-based modification plate sets the kilograms for the VIN. Use it to stay at or under 4,500 kg on a car licence, or when the truck is a private import and cannot take the federal package. The McGaughy's and BDS kits below are off the shelf. They are not the SSM stage table.
Signature kits
Off-the-shelf kits
These are the lift kits we sell for a state-based plate. Wheels, tyres, lights and a bar are open on this path. They are quoted with the kit, and they are listed under Add-ons.

Add to the build
Where a stage needs a load-rated wheel, we quote it with the package. It is not approved until the provider signs it off and the load rating meets the figure in the table. The order is an AEV wheel that fits this truck, then the KMC KM733 Impact FFT on an HD 8-lug, then Fuel Maverick or Fuel Vapor in 18x9 or 20x9 at +20. Method is not on this list. Tyres are a BFGoodrich Mud-Terrain T/A KM3 when a size meets the stage load index, or a BFGoodrich all-terrain. Lights and a bull bar sit outside the approved kit. A bar, winch or canopy adds kerb weight and uses payload.

Silverado 2500 GVM questions
Can I keep a car licence?
Not on these packages. 5,500 kg and 6,000 kg are NB2, which needs a Light Rigid licence, a zero blood-alcohol limit, and heavy-vehicle rules. To stay at or under 4,500 kg, that is State-Based Engineering and we set that rating for the VIN.
Will you do a private import?
No. This approval is GMSV Silverado 2500HD only, 2020 to 2026. A privately imported truck is State-Based Engineering, and the kilograms will not be these stage figures.
Does the 6.5 inch package carry more than the 3 inch package?
No. Stages 2 through 6.5 are 6,000 kg. The extra lift is stance and tyre size. Stage 1 is the only 5,500 kg package.
Which wheels can I run?
Every stage needs a wheel rated to at least 1,644 kg. We quote AEV first where it fits, then a KMC KM733 Impact FFT, then Fuel Maverick or Vapor at +20. Nothing is fitted until that wheel is signed off for the stage. Stages 1 to 5 need a 125Q tyre. Stages 6 and 6.5 need 128Q. A BFGoodrich KM3 is the tyre we spec when the size meets that index.
