Vehicle Compatibility

Important J120 / J125 Fitment Information

This Fabryka 4x4 drivetrain guard is specifically listed for both LCJ120 and LCJ125, so it can be used across both main body configurations of the Prado 120 Series.

• J120 – 5-door / long-wheelbase
• J125 – 3-door / short-wheelbase

This differs from the Fabryka 4x4 fuel tank guard in the same range, which is specifically listed for J120 only.

For this gearbox and transfer case protection plate, both J120 and J125 are supported by the manufacturer.

Technical Overview

Gearbox Protection

The gearbox is one of the most valuable drivetrain components underneath the Land Cruiser Prado 120 Series and can become vulnerable when the vehicle is driven across rocky tracks, deep ruts and uneven terrain.

Raised centre sections, exposed stone and hidden obstacles can strike the transmission casing directly. Significant impact damage can potentially lead to deformation, cracking, fluid loss or expensive drivetrain repairs.

The Fabryka 4x4 aluminium guard creates a substantial protective barrier beneath the gearbox, reducing direct exposure to these hazards.

Transfer Case Protection

The transfer case is a critical part of the Land Cruiser four-wheel-drive system, transmitting power between the front and rear driveline.

Because it sits underneath the centre of the vehicle, it can become exposed when crossing deep ruts, rocks and raised terrain.

Protecting the transfer case is particularly important on vehicles used in remote locations where drivetrain damage could leave the vehicle immobilised far from normal recovery access.

Combined Gearbox & Transfer Case Protection

Rather than protecting only one drivetrain component, this Fabryka 4x4 plate provides coverage for both the gearbox and transfer case.

This gives the centre underside of the vehicle broader protection against direct impacts and makes it a useful addition to vehicles used regularly on technical terrain.

Combined protection is particularly valuable when crossing:

• Deep ruts
• Rocky tracks
• Raised track centres
• Mountain trails
• Forestry roads
• Uneven agricultural tracks

Heavy-Duty 6mm Aluminium Construction

The guard is manufactured from substantial 6mm aluminium plate.

This considerable material thickness provides serious protection for the transmission and transfer case while retaining the advantages associated with aluminium underbody armour.

• Strong impact resistance
• Lower weight than comparable heavy steel armour
• Excellent natural corrosion resistance
• Suitable for wet, muddy and exposed environments
• Particularly suitable for touring and expedition vehicle builds

Precision Laser-Cut Construction

The aluminium plate is precision laser cut during production, allowing accurate mounting locations, external profile and detailed features to be reproduced consistently.

This is especially important for drivetrain protection because the plate must fit accurately beneath the gearbox and transfer case while maintaining suitable clearance around surrounding components.

Press-Brake Formed & Hand Finished

Following laser cutting, the aluminium plate is shaped using a press brake to create the required profile and structural geometry.

The guard is then hand finished during manufacture.

This combination of modern fabrication methods and manual finishing produces a vehicle-specific protection plate designed around the Toyota Land Cruiser J120 / J125 underbody.

Protection Against Common Off-Road Hazards

The gearbox and transfer case guard helps reduce exposure to:

• Rocks and exposed stone
• Deep wheel ruts
• Raised centre sections
• Tree roots
• Branches
• Mud and trail debris
• Hidden obstacles during water crossings
• Forestry tracks
• Agricultural roads

Complete Fabryka 4x4 Aluminium Protection System

This gearbox and transfer case guard forms the centre drivetrain section of the Fabryka 4x4 aluminium protection range for the Land Cruiser Prado 120 Series.

• 6mm Aluminium Engine & Sump Guard – J120 / J125 Diesel
• 6mm Aluminium Gearbox & Transfer Case Guard – J120 / J125 – this product
• 6mm Aluminium Fuel Tank Guard – J120 5-Door / LWB

J120 5-Door / Long-Wheelbase Protection Package

For the J120 5-door / long-wheelbase model, this gearbox and transfer case guard can be combined with both the front engine protection and the J120-specific fuel tank guard.

• Fabryka 4x4 Aluminium Engine & Sump Guard
• Fabryka 4x4 Aluminium Gearbox & Transfer Case Guard
• Fabryka 4x4 Aluminium Fuel Tank Guard – J120

This gives the J120 broad protection across the front, central drivetrain and fuel tank areas.

J125 3-Door / Short-Wheelbase Protection

The J125 3-door / short-wheelbase model can also use this gearbox and transfer case guard because Fabryka 4x4 specifically lists the product for LCJ120/125.

For diesel J125 vehicles, it can be paired with the matching:

Fabryka 4x4 6mm Aluminium Engine & Sump Guard – J120 / J125 Diesel

The J120-specific Fabryka 4x4 fuel tank guard should not be assumed to fit the J125.

Existing Steel Land Cruiser 120 Protection

OFM4x4 also offers steel protection alternatives for the Land Cruiser Prado 120 Series.

• Steel Engine & Sump Guard
• Steel Gearbox Guard
• Steel Fuel Tank Guard – 5-Door / LWB
• Steel Fuel Tank Guard – 3-Door / SWB

Existing 4mm Aluminium Alternatives

OFM4x4 also offers lighter 4mm aluminium protection options for the Land Cruiser 120 Series:

• 4mm Aluminium Engine & Sump Guard
• 4mm Aluminium Gearbox Guard

The Fabryka 4x4 system uses substantial 6mm aluminium and extends the drivetrain protection to both the gearbox and transfer case.
