Aluminum vs Steel Bash Plates: Which One Is Better for Off-Roading?

Understanding Your Options

Choosing the right bash plate for your 4x4 is critical when facing Australia's tough off-road conditions. Whether you prefer rocky trails, desert crossings, or muddy tracks, proper underbody protection ensures your vehicle can tackle any challenge.

The two most common options are aluminum and steel bash plates. Let's compare their strengths to help you choose the best fit for your adventures.

Aluminum Bash Plates

Aluminum bash plates offer a combination of lightweight performance and corrosion resistance. They are strong enough to protect your vital underbody components while keeping your vehicle’s weight down — a major advantage for fuel efficiency and handling.

Benefits of aluminum bash plates:

  • Lightweight, improving off-road handling
  • Rust-proof, ideal for wet or coastal environments
  • Easier to install and remove
  • Precision engineering for a perfect fit

Steel Bash Plates

Steel bash plates are heavier but offer extreme impact resistance, making them a popular choice for drivers who tackle harsh, rocky terrains. However, steel plates require proper coating and maintenance to resist rust over time.

Benefits of steel bash plates:

  • Exceptional impact resistance
  • Lower upfront cost compared to aluminium
  • Suitable for extremely rugged environments

Which Bash Plate Should You Choose?

Aluminum Bash Plates Steel Bash Plates
Best for general off-roading and touring Best for extreme rocky terrains
Lightweight and corrosion-resistant Heavier but ultra-tough
Ideal for coastal and wet climates Requires proper rust prevention


If you value lighter weight, superior corrosion resistance, and easy installation, aluminum is your best choice.
If you often drive through extremely rocky, harsh environments, steel may offer added protection.
