The Isuzu D-MAX is already a capable tourer straight from the factory — but load it up properly and the factory GVM disappears fast. A federally approved GVM upgrade gives you more legal payload, better suspension under load, and the confidence to run your D-MAX the way it was actually built for.
Factory GVM is 3100kg. All three upgrade tiers bring this up to 3695kg, with GCM options from 6200kg up to 6900kg depending on the kit selected.
Professionally installed by BAW Automotive in Brisbane. Wheel alignment included in all packages. Pre-registration SSM approval included — compliance plate fitted to vehicle.
SUIT MODELS: Isuzu D-MAX RG1 — 3.0L Diesel — 10/2021 On
PLEASE NOTE: Pricing does not include load-rated wheels and tyres, and does not include engineering certification for post-registration installation. Factory tyres are compliant.
