Typical Isuzu projects
KME Vehicle Engineering has completed engineering work across both Isuzu NPS and NPR trucks and Isuzu MU-X 4WDs, covering GVM and GCM upgrades, suspension and wheel changes, super single conversions, towing-related modifications and other vehicle-specific engineering.
Our experience spans heavy-vehicle NPS/NPR applications and light-vehicle MU-X builds, with each project assessed against the vehicle’s actual configuration, intended operating mass, fitted components and registration jurisdiction.

Super Single Conversions: Why certification, tyre pressures and ratings matter
Common Isuzu modifications - what do you need certified?
GVM upgrades
Typical upgrades
Isuzu NPS 300: 6,000 → 7,500 kg
Isuzu NPR 65-190: 6,500 → 7,500 kg
Isuzu NPS 75-155: 7,500 → 8,000 kg
MU-X (2021 onwards): 2,800 → 3,300 kg
MU-X (2013–2020): 2,750 → 3,200 kg
GCM and towing assessments
NPS 300: GCM from 9,500 kg to 11,000 kg.
NPR 65-190: GCM 10,000 kg to 11,000 kg
NPS 75-155: GCM 11,000 kg to 12,000 kg
Tow hitches and couplings
Assessment of an Isuzu tow pin under a defined load case. Component strength findings apply to the assessed design and assumptions.
Suspension modifications
Engineering assessment of suspension components and mounting arrangements, including Isuzu NPS shock mounts, for the proposed configuration and operating loads.
Body and chassis modifications
Assessment of body mounting, structural connections and load distribution for trays, service bodies and tipper installations.
Example Isuzu projects by KME Vehicle Engineering
Isuzu NPR 65-190 GVM Upgrade to 7,500 kg — Queensland
GVM, Heavy vehicle
KME certified an Isuzu NPR 65-190 van truck GVM increase from 6,500 kg to 7,500 kg under VSB 6 codes G4, S1 and S2, following vehicle-specific inspection and testing. Certification was completed under the Queensland heavy-vehicle modification framework. GCM remained unchanged at 10,000 kg for this vehicle.
Isuzu MU-X King/Bilstein Suspension & 3,150 kg GVM — NT
GVM, Suspension, Vehicle Modification
Daly Kelly certified an Isuzu MU-X GVM increase from 2,750 kg to 3,150 kg through Omega Operations in the Northern Territory. King coils and Bilstein dampers were assessed with comparative analysis, inspection and on-road testing. The front axle rating was limited to suit the fitted springs; GCM remained unchanged. The outcome applies to the nominated components.
Isuzu MU-X 2022 GVM Upgrade to 3,300 kg — NT
GVM, Vehicle Modification
Vehicle-specific KME certification of a 2022 Isuzu MU-X GVM upgrade from 2,800 kg to 3,300 kg under the Northern Territory VS24 process. The vehicle retained category MC. The certified rating applies to this assessed configuration; no GCM or towing-capacity increase is claimed.
Isuzu MU-X 2018 GVM Certification to 3,200 kg — NT
GVM, Vehicle Modification
Daly Kelly certified a 2018 Isuzu MU-X to 3,200 kg GVM under the Northern Territory VS24 process while operating through Omega Operations. The vehicle retained category MC. This earlier-generation project is vehicle-specific and does not establish a GCM or towing-capacity increase.
Isuzu NPS 300 GVM & GCM Upgrade — Queensland
GVM, GCM, Heavy vehicle
Queensland-certified Isuzu NPS 300 heavy-vehicle upgrade: GVM increased from 6,000 kg to 7,500 kg and GCM from 9,500 kg to 11,000 kg following vehicle-specific engineering assessment and brake testing under VSB 6 codes G4, S1, S2 and S3.
Isuzu NPS 75-155 GVM & GCM Upgrade — NSW
GVM, GCM, Heavy vehicle
Engineering certification of an Isuzu NPS 75-155 GVM increase from 7,500 kg to 7,995 kg and GCM increase from 11,000 kg to 12,000 kg under VSB 6 G4, S1, S2 and S3.
Isuzu Super Single Wheel Conversion
Heavy vehicle, Vehicle Modification
Conversion of an Isuzu coach from dual rear wheels to super single tyres for Pinnacle Coaches.
