Isuzu D-Max / Mazda BT-50 (2021–Present) — Set of 2 Aluminium Bash Plates — Engine & Transmission
Combined Weight: 10 kg
Weighing just 10 kg for two plates, this RIVAL 4x4 Set of 2 Aluminium Bash Plates is the lightest way to protect the engine and transmission on your Isuzu D-Max or Mazda BT-50. For owners who need underbody protection but are watching every kilogram of their GVM allowance — and that's most D-Max and BT-50 owners — this ultra-lightweight set delivers genuine protection without meaningful compromise to payload capacity. Precision-cut aluminium bolts directly to factory mounting points for a seamless fit, and the corrosion-resistant finish means these plates are ready for whatever Australian conditions you throw at them from day one.

What's Protected
-
Engine Bash Plate — The D-Max's turbo diesel engine relies on its sump pan for oil supply, and that pan sits exposed beneath the vehicle with minimal factory protection. A rock strike at even low speed can crack the sump, leading to oil loss and engine seizure. This lightweight aluminium plate provides effective coverage to the engine underside, deflecting rocks and trail debris before they can do damage.
-
Transmission Bash Plate — The gearbox casing extends behind the engine, vulnerable to rocks, ruts, and debris that pass beneath the vehicle. A compromised transmission housing leaks fluid and leads to loss of drive — a failure that's both expensive and dangerous in remote locations. This plate shields the entire transmission assembly from trail hazards.

Why Choose Aluminium Over Steel?
-
Ultra-Lightweight: At just 10 kg for two plates, the weight impact on your GVM is virtually zero — perfect for payload-conscious D-Max and BT-50 owners.
-
Natural Corrosion Resistance: Aluminium doesn't rust. It's inherently suited to Australia's water crossings, coastal environments, and tropical humidity.
-
Effective Energy Absorption: Aluminium distributes impact force across the plate, protecting mounting points and chassis from concentrated shock.
-
Modern Protection: Aluminium alloy delivers genuine rock-strike protection at a fraction of the weight of traditional steel plates.
