On a long stretch off tarmac what counts is not how strong a single plate is, but whether there is a spot under the truck with nothing over it at all. This kit covers the D-Max from the radiator back to the fuel tank.

Areas covered: radiator, engine, gearbox, transfer case and fuel tank. Rival lists those five components while describing the set as a four-piece kit — we confirm that discrepancy in its data before shipping. That is the full path from the bumper to the rear axle — everything on this truck that ends a trip when it gets damaged far from a workshop.

6.0 mm aluminium. Every plate is made from 6.0 mm aluminium in a silver finish. Alloy weighs less than steel of comparable resistance — and on a kit spanning half the underbody that difference stops being theoretical.

Installation. A fitting kit is included. It is a job our workshop can take on.

Fitment. Isuzu D-Max from 2021 (model years 2021-2023 and 2023-), 1.9 l, 2.0 l and 3.0 l diesel, Euro 6 included.
