Hilux Bash Plates and Dual Battery Tray: Essential 4x4 Upgrades for Serious Off-Roading
When it comes to taking your Toyota Hilux off the beaten track, two essential upgrades can make a major difference in durability and functionality: Hilux bash plates and a dual battery tray Hilux setup. These aren’t just accessories—they’re key to protecting your vehicle and supporting power-hungry gear during long trips.
What Are Hilux Bash Plates and Why Do You Need Them?
Upgrading to Hilux bash plates made from high-tensile steel or aluminium ensures your underbody is shielded from serious off-road abuse. For those who frequently explore Australia’s rugged terrains—whether it's river crossings, steep inclines, or rocky trails—investing in high-quality bash plates is essential for peace of mind and vehicle longevity.
Key Benefits of Aftermarket Hilux Bash Plates
Premium Hilux bash plates are designed to:
Absorb direct impacts from rocks and debris
Protect critical components from damage
Improve off-road clearance with a contoured fit
Reduce the risk of fluid leaks caused by underbody strikes
Some models also feature drainage holes, making maintenance easier without removing the entire plate. The best bash plates are also powder-coated to resist rust and corrosion, which is important when dealing with wet or muddy conditions.
Material Choices: Steel vs Aluminium
Steel bash plates are heavier but offer maximum durability, especially in extremely rough conditions. Aluminium plates, on the other hand, are lighter and more resistant to corrosion, making them a good option for those seeking weight savings while still maintaining underbody protection.
Your choice depends on your driving style. If you're tackling extreme tracks, steel may be the way to go. For occasional off-roaders or overlanders concerned with fuel economy, aluminium could be more suitable.
Why Install a Dual Battery Tray in Your Hilux?
When you’re running a fridge, LED lighting, UHF radios, or other power-hungry equipment while camping or touring, a dual battery system is a game changer. A dual battery tray Hilux allows for the safe and stable installation of a second battery—usually deep cycle—under the bonnet or in the tray area.
This setup ensures your main battery is used exclusively for starting the engine, while the second battery powers accessories. It prevents you from getting stranded with a flat starter battery, which is especially important when you’re in remote locations.
Types of Dual Battery Setups for Hilux Owners
There are a few options when considering a dual battery tray Hilux upgrade:
Under-bonnet trays: Great for compact, tidy installations and convenient wiring access.
Tray-mounted systems: Useful if you need a higher capacity battery or if the engine bay has limited space.
Canopy systems: Ideal for tradies or touring setups that run multiple devices like fridges, work lights, or inverters.
Each type requires a solid mounting system and often includes isolators or DC-to-DC chargers to properly manage charge levels between the starter and auxiliary battery.
Things to Consider Before Installing a Dual Battery Tray
Before choosing your dual battery tray Hilux, think about the following:
Battery size compatibility: Make sure your tray fits your chosen battery.
Ventilation: Some batteries require venting if they're located in a sealed space.
Charger compatibility: Lithium and AGM batteries have different charging needs.
Ease of maintenance: Access for checking battery levels or wiring must be simple.
Most dual battery tray kits come with pre-drilled holes and mounting hardware tailored for specific Hilux models, ensuring a secure and vibration-free installation.
Complementary Upgrades for Serious Touring Builds
If you're fitting Hilux bash plates and a dual battery tray Hilux, you're probably also considering a more comprehensive 4WD build. These upgrades often go hand-in-hand with:
Suspension lifts and GVM upgrades
Snorkels for water crossings
Winches and recovery points
Roof racks and rooftop tents
Rear drawers or canopy storage systems
Together, they create a purpose-built touring or off-road setup that is capable, self-sufficient, and safe for long trips across Australia’s harshest environments.
Installation Tips and Professional Help
While some experienced 4WDers tackle installation themselves, many choose to have Hilux bash plates and dual battery trays professionally fitted. Bash plate installation requires access to the undercarriage and torqueing bolts to spec. Battery tray installation must be secure and wired correctly to avoid electrical issues.
A licensed auto electrician or 4WD specialist in your area can assist with both, ensuring that your upgrades perform reliably under all conditions.
Final Thoughts on Hilux Bash Plates and Dual Battery Trays
If you’re serious about taking your Hilux off-road or heading out on extended remote trips, upgrading with Hilux bash plates and a dual battery tray Hilux setup is a smart move. Bash plates protect your investment, while the dual battery system keeps you powered no matter where you camp.
Both upgrades boost reliability, functionality, and confidence on the trail—essential attributes when the terrain gets tough, and help is hours away.
