Underbody Protection Plates Designed for Australian Off Road Conditions

Underbody protection plates help reduce the risk of damage to essential drivetrain components when travelling over rocks, ruts, washouts and uneven tracks.

GMF 4x4 underbody protection kits are manufactured from high strength aluminium or steel and designed to integrate with factory mounting locations for a secure installation.

They are commonly used to protect:

  • engine sumps
  • transmission components
  • transfer cases
  • crossmembers
  • chassis mounted systems

Vehicle specific design ensures proper clearance while maintaining service access where required.

Rear Differential Guards, Steering Arm Guards and Sensor Protection Brackets

Differentials, steering arms and exposed sensors are some of the most vulnerable components on modern 4WD vehicles when travelling off-road.

GMF 4x4 protection brackets are designed to shield these areas from impact damage caused by rocks, ruts and uneven terrain while maintaining correct component clearance.

Our protection range includes:

  • rear differential guards
  • steering arm guards
  • ABS sensor protection brackets
  • trailing arm sensor guards
  • module protection guards

These components are particularly valuable for touring vehicles operating on corrugated roads or technical tracks where exposed drivetrain parts are at greater risk.

Fuel Filter Guards and Module Protection for Remote Touring Vehicles

Fuel filter housings and electronic modules mounted along the chassis are vulnerable to damage when travelling off road or through debris covered tracks.

GMF 4x4 fuel filter guards and module protection brackets provide an additional layer of protection for these exposed components without interfering with servicing access.

They are commonly installed on:

  • Ranger
  • Hilux
  • D-MAX
  • BT-50
  • LandCruiser
  • Silverado

Protecting these systems helps reduce the risk of unexpected failures during remote travel where recovery or repairs may not be immediately available.

Browse the GMF 4x4 vehicle protection range above to find the correct solution for your vehicle platform.
