Isuzu D-Max / Mazda BT-50 (2021–Present) — Bash Plate Set — Engine & Transmission
Essential Front Underbody Protection: Engine & Transmission Bash Plates
Installation Manual
Combined Weight: 21.9 kg
The engine and transmission are the two most critical — and most expensive — components beneath your Isuzu D-Max or Mazda BT-50. They're also the most commonly damaged in off-road impacts. This RIVAL 4x4 Set of 2 Bash Plates provides precision-fit protection for both components in a lightweight, cost-effective package. At just 21.9 kg combined, these plates barely affect your payload capacity, making them the ideal first step for any D-Max or BT-50 owner who wants essential underbody protection for weekend tracks, rural roads, and the daily commute alike.

What's Protected
-
Engine Bash Plate — The D-Max's 3.0-litre turbo diesel sump is the lowest point on the vehicle and the most likely to contact rocks, stumps, and trail debris. Even a moderate impact can crack the aluminium oil pan, leading to rapid oil loss and engine seizure. In regional Australia, where the nearest mechanic might be hundreds of kilometres away, a seized engine means a recovery bill in the thousands. This plate delivers comprehensive protection across the engine's entire underside.
-
Transmission Bash Plate — Immediately behind the engine, the gearbox housing is exposed to every rock and rut that slides beneath the vehicle. The transmission casing is precision-machined and not designed to absorb trail impacts — a single hit can crack the housing, causing fluid loss and complete drivetrain failure. This plate guards the gearbox from below, keeping you moving no matter the terrain.

Why Choose Aluminium Over Steel?
-
Negligible Weight: Two plates at 21.9 kg barely impacts your GVM — critical for D-Max and BT-50 owners who already run close to payload limits.
-
Corrosion-Free: Aluminium naturally resists rust, making it perfect for utes that ford creeks, drive beaches, and sit in coastal salt air.
-
Impact Distribution: Aluminium's flex properties spread rock-strike energy across the plate, protecting mounting hardware and the chassis from concentrated force.
-
Smart Engineering: 6mm aluminium delivers genuine protection at a fraction of the weight of steel — the intelligent choice for weight-conscious builds.

Built for Australian Conditions
The D-Max and BT-50 are among Australia's hardest-working utes, and they encounter every road condition the country has to offer. From the gravel highways of outback South Australia to the rocky mountain tracks of the Snowy Mountains, from coastal sand at Bribie Island to the muddy logging roads of the Otways, your underbody faces constant threats. RIVAL 4x4 bash plates are built to absorb this punishment. The powder coat finish resists salt, dust, mud, and UV exposure, while ventilated design keeps engine bay temperatures manageable during slow-speed trailing in summer.
