An Isuzu D-Max GVM upgrade costs $6,040 to $9,356 fully fitted at Fulcrum Suspensions, depending on the kit and model year. The most popular option, the 3700kg Formula 4x4 kit for the 2021 to 2024 D-Max, is $6,040 fitted. Post-registration upgrades add $1,265 for engineering and a new modification plate.
When you’re budgeting for a D-Max GVM upgrade, the kit price is only part of the story. You also need fitting, an alignment, the GVM handling and, for a ute that’s already registered, the engineering sign-off. Our Dmax GVM upgrade cost figures below are full fitted prices, so you can compare the real number. Every kit is listed in our full range of Isuzu D-Max GVM upgrades.

Extra Costs to Plan For
Post-registration engineering
If your D-Max is already registered, an engineer needs to inspect the installation, issue a modification plate and update your registered details. That adds $1,265 to the fitted price of any kit. For a new D-Max ordered with a pre-registration upgrade, the engineering is included at no extra charge.
Upper control arm kit on Lovells kits
If your D-Max is already registered, an engineer needs to inspect the installation, issue a modification plate and update your registered details. That adds $1,265 to the fitted price of any kit. For a new D-Max ordered with a pre-registration upgrade, the engineering is included at no extra charge.
Tyres
Your tyres need a load rating that suits the upgraded axle loads. If your current tyres fall short, budget for a set that does.

The Formula 4x4 standard kit stands out for value. It gives you 100kg more GVM than the Lovells kits, uprated axle ratings front and rear, an upper control arm kit and a 5 year / unlimited km warranty, all for the lowest fitted price in the range. The only reason to look past it is if you need the GCM increase or adjustable damping.
Is a D-Max GVM Upgrade Worth the Money?
If your D-Max is already near 3100kg with accessories and gear on board, an upgrade is the only legal way to keep carrying that load. Driving over GVM risks fines, defect notices and problems with an insurance claim.
There’s a real ride and safety benefit too. Springs and shocks matched to the load cut rear sag, steady the D-Max over corrugations and keep steering and braking more predictable when you’re loaded up.
Not sure you need one yet? Book a $90 GVM & Towing Assessment and we’ll weigh each corner of your D-Max before you spend a cent on a kit. To understand where your current limits sit, read our guide to Isuzu D-Max payload capacity. Our guide to the D-Max GVM covers the factory ratings by model year, and if you tow a heavy van, our Isuzu D-Max GCM guide shows when the Lovells GCM kit is worth the extra cost.
