Aluminium Transmission Bash Plate — Isuzu D-Max / Mazda BT-50 (2021–Present)
Weight: 11 kg
When you're navigating the ridgelines of the Great Dividing Range, where steep descents over loose rock put your underbody directly in the firing line, your Isuzu D-Max's transmission housing is one of the most vulnerable and expensive components beneath the vehicle. A cracked gearbox casing means total drivetrain failure — no gears, no drive, no getting home under your own power. The RIVAL 4x4 Transmission Bash Plate for the D-Max and BT-50 (2021+) delivers precision-engineered protection for your gearbox housing — a precision component that's both expensive to replace and vulnerable to rock strikes. Crafted from deep-stamped 6mm high-strength aluminium alloy, this 11 kg plate provides serious, full-coverage transmission protection.

Why Choose Aluminium Over Steel?
-
Weight Savings: Aluminium is approximately 40% lighter than steel, keeping your D-Max or BT-50 within GVM while protecting the transmission from the worst Australia can throw at it.
-
Corrosion Resistance: Unlike steel, aluminium naturally forms a protective oxide layer. Combined with powder coating, your bash plate won't rust — even after years of salt-air exposure, water crossings, and red-dust trails.
-
Energy Absorption: Aluminium's natural flex absorbs and distributes impact energy across the plate rather than transferring sharp jolts directly to the gearbox housing and mounting points.
-
Modern Vehicle Design: The D-Max and BT-50 feature advanced 6-speed automatic transmissions that demand lightweight, precision protection — not heavy steel that compromises payload.

Built for Australian Conditions
The Isuzu D-Max and Mazda BT-50 are trusted workhorses across rural Australia. From mine sites in the Pilbara to cattle stations in the Gulf Country, from beach access tracks on the east coast to forestry roads in Tasmania — these utes go everywhere. And everywhere they go, rocks, stumps, and trail debris target the exposed transmission housing.
RIVAL bash plates are engineered for this demanding reality. The deep-stamped construction creates integrated stiffening ribs that provide up to two times the impact resistance of flat-plate designs. The powder coat finish resists UV degradation, salt corrosion, and the abrasive conditions that Australian vehicles endure daily.
Perfect For
- Long-distance outback touring — Cape York, Gibb River Road, Simpson Desert
- Coastal driving where salt air accelerates corrosion on exposed drivetrain components
- Tradies and fleet vehicles operating on construction sites, farms, and mining roads
- Serious off-road adventures including rock crawling, river crossings, and rutted tracks
- Daily driving with peace of mind knowing your transmission is protected from road debris and hazards
