Already registered, or a private import? We engineer GVM upgrades for the 6.7L Cummins RAM 2500 right here in Queensland, taking it up to its factory axle ratings. That's up to 5,460 kg on the 5th gen and 5,320 kg on the 6th gen, more than doubling the factory payload.
Every package takes the truck to its axle limit: 5,460 kg on the 5th gen, 5,320 kg on the 6th gen. The step up is in the suspension, ride and lift.
Suits: 6.7L Cummins RAM 2500, 5th gen and 6th gen, including registered trucks and private imports. The 6.4L HEMI Warlock is enquiry only. Upgrades over 4,500 kg move the truck to NB2, which needs an LR licence.
The most affordable way to a legal NB2 RAM 2500, right up to the factory axle ratings.
The premium ride, with Fox shocks and the option of a 2 to 3 inch lift. Priced to your build.

Prices include parts, fitting and Queensland engineering. Wheels and tyres are extra. Your final price is confirmed on your quote.
The factory wheels are rated to 1,587 kg each. Lifts of 2 to 3 inches with tyres up to 35 inch can go on the QLD modification plate as part of the same engineering.
If you change wheels or tyres, they need to carry the new axle loads. We'll quote load-rated options on the same job.
Both can be upgraded to their factory axle ratings. On the 5th gen that's 5,460 kg, for up to 1,851 kg of payload (1,793 kg with RamBox). The 6th gen High Output has lower front axle ratings, so it goes to 5,320 kg, for up to 1,610 kg of payload (1,540 kg with RamBox).
GCM and 4,500 kg braked towing stay at the factory figures on both.
Fitting a long range fuel tank at the same time? It goes on the same engineering, with no extra engineering fee.
There are kits on the market that go higher, but the 2500's rear coil springs aren't the right base for it. If you need more, a leaf-sprung truck like a RAM 3500 or Silverado 2500HD is the better starting point, and we can help with that too.
These packages are for the 6.7L Cummins. If you've got a 2500 Warlock with the 6.4L HEMI, get in touch and we'll look at what's possible for your truck.
One workshop handles the whole job: the kit, the wheels and tyres it needs, the fit and the paperwork.
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.
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.
Fitted in our Brendale workshop with the supplier's engineering. Most fits take 2 to 3 days. Chassis extensions take longer.
You leave with the certification paperwork and an alignment set for the new ride height and load.
Yes. It's an engineered modification done after registration. The truck is inspected, the upgrade is designed around its axle, tyre and component ratings, and it's certified by an independent Queensland approved person (engineer). You get a modification certificate and an updated plate.
Over 4,500 kg GVM, yes. The truck moves from NB1 to NB2, and the driver needs a light rigid (LR) licence. A car licence covers up to 4,500 kg.
No. GCM and braked towing stay at the factory figures: 4,500 kg braked towing, with a GCM of 12,695 kg on the 5th gen and 12,750 kg on the 6th gen. The upgrade gives you payload headroom, so you can load the truck properly.
Moving to NB2 can change your rego class and cost. Let your insurer know about the upgrade and keep the certificate with the truck. We'll go through it with you before any work starts.
Not these packages. They're for the 6.7L Cummins. Warlock owners can still get in touch and we'll look at what's possible.
We don't recommend it on a RAM 2500. Its rear coil springs aren't designed for more. For heavier loads, a leaf-sprung RAM 3500 or Silverado 2500HD is the better base.
Yes. Because we engineer the upgrade after registration, we can do registered RAM 2500s, including private imports.
Tell us whether it's a 5th or 6th gen, how it's set up, what you carry and what you tow. We'll recommend the right package and quote it with wheels and tyres to suit.
