Isuzu D-Max / Mazda BT-50 (2021–Present) — Bash Plate Set — Engine, Transmission, Transfer Case & Fuel Tank
Extended Underbody Protection: 4-Plate Set Covering Engine Through to Fuel Tank
Installation Manual
Combined Weight: 37.3 kg
For Isuzu D-Max and Mazda BT-50 owners who want comprehensive protection without the full five-plate kit, this RIVAL 4x4 Set of 4 Bash Plates covers the four most critical components from front to rear — engine, transmission, transfer case, and fuel tank. These are the components that, if damaged on a remote track, will either strand you completely or create a genuine safety hazard. At 37.3 kg combined, this set delivers serious coverage while keeping weight manageable on these payload-sensitive utes. The bundle price means you get all four plates for less than buying them individually.

What's Protected
-
Engine Bash Plate — The D-Max's 3.0-litre turbo diesel has an exposed aluminium sump that sits low beneath the chassis. One solid rock impact cracks the pan, oil drains in minutes, and you're looking at engine seizure and a massive repair bill. On a track hours from the nearest town, that's not just expensive — it's dangerous. This plate provides full coverage to the engine's underside.
-
Transmission Bash Plate — The gearbox housing extends behind the engine, exposed to rocks and debris that the engine plate doesn't catch. Whether manual or automatic, a cracked transmission casing means fluid loss and zero drive. This plate ensures the gearbox stays intact through the toughest terrain.
-
Transfer Case Bash Plate — The transfer case sits centrally, splitting power between front and rear axles. It's low, exposed, and directly in the path of every rock that slides beneath the vehicle. A damaged transfer case disables your 4WD system when the terrain demands it most. This plate provides dedicated protection.
-
Fuel Tank Bash Plate — The fuel tank carries your entire fuel supply beneath the rear of the vehicle. A punctured tank in remote Australia turns a trip into a survival situation. This plate protects the component that determines how far you can travel and how safely you can return.

Why Choose Aluminium Over Steel?
-
Payload Preservation: The D-Max and BT-50 have strict GVM limits. Four aluminium plates at 37.3 kg leaves room for tools, camping gear, and passengers that a heavier steel set wouldn't.
-
Corrosion Immunity: Aluminium doesn't rust. It thrives in the water crossings, coastal salt spray, and tropical humidity that are part of everyday Australian 4WD life.
-
Energy Absorption: Aluminium distributes impact force across its surface, reducing the shock transferred to mounting points and the vehicle's chassis rails.
-
Lightweight Strength: 6mm aluminium alloy provides meaningful protection without the weight penalty that pushes these utes over their GVM limits.

Built for Australian Conditions
D-Max and BT-50 owners take their utes everywhere — from the rocky river crossings of the Kimberley to the corrugated roads of the Channel Country, from the sandy tracks of Moreton Island to the muddy forest trails of Tasmania's west coast. Every surface presents a different threat to your underbody. RIVAL 4x4 bash plates are engineered for all of them. The corrosion-resistant powder coat finish handles years of salt, mud, dust, and humidity, while the ventilated design maintains healthy operating temperatures during slow-speed crawling in peak Australian summer.
