Rival 4x4 Aluminium Underbody Protection for the Toyota Hilux
Rival 4x4 is a full aluminium underbody protection system for the Toyota Hilux, covering the four spots that cop the most damage off-road: the engine, the transmission, the transfer case and the fuel tank. It fits both the N70 Hilux (2005-2015) and the N80 Hilux (2015-2025), with several plates also carrying across to the matching Fortuner. Built from 6mm aluminium, it gives you full underbody coverage without the weight penalty that comes with steel. We fit this gear at our Perth workshop and this page walks through what it protects, why aluminium, and which guard suits your exact year.

Are Aluminium Bash Plates Worth It on a Hilux?
Short answer: if you leave the bitumen, yes. Factory Hilux underbody protection is thin stamped steel or plastic that's there for the occasional gutter, not for rock shelves, stumps and washouts. A proper bash plate stops a hidden rock caving in your sump, fuel tank or transfer case a long way from help.
The choice most owners weigh is aluminium versus steel. Here's how Rival's 6mm aluminium stacks up against a typical 3mm steel plate and the factory setup:
| Option | Weight on GVM | Corrosion | Coverage |
|---|---|---|---|
| Factory (thin steel/plastic) | Light but token | Rusts, especially the fuel tank cradle | Partial, road-focused |
| 3mm steel aftermarket | Heaviest, eats into payload | Rusts unless well coated | Full, but adds real kilos |
| Rival 6mm aluminium | Lighter than typical 3mm steel, easier on GVM | Corrosion-resistant, no rust | Full engine, transmission, transfer case and fuel tank |
The trade-off is straightforward. Steel is cheaper per plate and shrugs off repeated dragging, but the weight comes straight off your payload, and on a Hilux you're already fighting for kilos once you add a bar, canopy and gear. Aluminium keeps full coverage while being lighter than typical 3mm steel, so you protect the driveline without crushing what you can legally carry.
Toyota Hilux Aluminium Bash Plates: What Makes Rival 4x4 Different?
Rival 4x4 is built specifically around lightweight aluminium underbody armour, with a range engineered specifically to vehicle-level fitment, not generic sizing. The specifics we can state as plain fact:
- 6mm aluminium construction: full-coverage guards that are lighter than typical 3mm steel plates, so easier on GVM and payload.
- Corrosion-resistant: aluminium doesn't rust, which matters on a vehicle where the underbody sees mud, salt and water crossings.
- ADR69-compliant and airbag/sensor compatible: the plates are designed to work with the Hilux's factory safety systems, not compromise them.
- Winch-ready with integrated recovery points and fog-light mounts: the front components are set up for serious remote-travel builds.
- Backed by Rival's official warranty.
That's the honest case for the range: a full aluminium underbody guard set that protects the driveline while staying light enough not to wreck your load rating.
Which Rival Underbody Guards Fit My Hilux? (N70 2005-2015 vs N80
Rival sells the underbody armour as individual guards so you can build up coverage in stages or protect just the vulnerable spots. Match the guard to your generation and the component you're protecting.
N70 Hilux (2005-2015)
- Aluminium fuel tank underbody armour, protecting the tank on the 2005-2015 Hilux.
- Aluminium transfer case underbody armour for the same years.
- Aluminium transmission underbody armour, which also suits the Fortuner 2011-2015.
N80 Hilux (2015-2025)
- Aluminium fuel tank underbody armour for the 2015-on Hilux.
- Aluminium transmission underbody armour, also fitting the Fortuner 2015-on.
- Aluminium transfer case underbody armour and the lower control arm underbody guard for 2015-on.
The range covers the N80 well, and there are also bonnet struts listed for the 2015-on Hilux and Fortuner. Because the mounting points differ between generations, get the year right before you order, and if you're unsure, confirm the right part with us. If you're building the N80, our N80 Hilux lift kits pair well with underbody protection. For the earlier ute, see our 2005-2015 KUN Hilux parts.
Setting Up a Winch-Ready Touring Hilux
For remote-travel and recovery builds, Rival's front underbody design is winch-ready with integrated recovery points and fog-light mounts. Ask our team to confirm which Rival winch mount and recovery points suit your build. It's a tidy setup for touring where you might be self-recovering across sand, mud or river crossings. Round out the build with Hilux rock sliders and side steps to protect the sills against rocks and ledges.

Frequently Asked Questions
Are bash plates worth it on a Hilux?
If you go off the bitumen, yes. Factory Hilux underbody protection is minimal, and a hidden rock can crack a sump, fuel tank or transfer case. A 6mm aluminium plate spreads the hit and protects the driveline, which is a lot cheaper than a recovery and a new gearbox.
Is a bash plate necessary for touring and remote travel?
For serious off-road and remote work, it's close to essential. Corrugations, rock shelves and river crossings all put the underbody at risk. Full engine, transmission, transfer case and fuel tank coverage means you're not gambling your driveline a long way from help.
Are Toyota Hilux prone to rust?
Underbody components on any ute exposed to mud, salt and water can corrode over time, and steel plates rust unless they're kept coated. Rival's aluminium construction doesn't rust, which is a real advantage on a vehicle that spends time in wet, salty or muddy conditions.
What are the benefits of Rival 4x4 underbody armour?
6mm aluminium construction that's lighter than typical 3mm steel so it's easier on your GVM, corrosion-resistant, ADR69-compliant and airbag/sensor compatible, and winch-ready with integrated recovery points and fog-light mounts. It's all backed by Rival's official warranty.
How do I protect my Hilux underbody?
Fit full underbody armour across the four vulnerable areas: engine, transmission, transfer case and fuel tank. You can add the guards in stages or as a set. Match each guard to your generation (N70 2005-2015 or N80 2015-2025), and if you're unsure which parts suit your build, contact us and we'll sort the right fitment.
