Fabryka 4x4 Aluminium Gearbox & Transfer Case Guard for Toyota Land Cruiser Prado 150 J150 2017-On – 6mm

The Fabryka 4x4 Aluminium Gearbox & Transfer Case Guard is a heavy-duty, vehicle-specific underbody protection plate designed for the Toyota Land Cruiser Prado 150 / J150 from 2017 onwards.

Manufactured from substantial 6mm aluminium plate, the guard provides dedicated protection beneath both the gearbox and transfer case, helping shield these critical drivetrain components against rocks, deep ruts, raised ground, mud, branches and other obstacles encountered during demanding off-road use.

The protection plate is precision laser cut, press-brake formed and hand finished by Fabryka 4x4 to provide accurate vehicle-specific fitment and durable underbody protection for green-laning, overlanding, expedition travel and working 4x4 applications.

Vehicle Compatibility

Important 2017-On Fitment

This Fabryka 4x4 OLN gearbox and transfer case guard is specifically intended for Toyota Land Cruiser J150 models from 2017 onwards.

The J150 received significant revisions during its production life, and Fabryka 4x4 produces separate drivetrain protection for the earlier and later versions.

• 2017-On Gearbox & Transfer Case Guard – this product

Please confirm the vehicle production year before ordering.

Technical Overview

Heavy-Duty Gearbox Protection

The gearbox is one of the most important and expensive drivetrain components underneath the Toyota Land Cruiser J150.

When travelling across deep ruts, rocky terrain or tracks with raised centres, the underside of the transmission can become vulnerable to direct impacts.

A severe strike can potentially result in:

• Damage to the gearbox casing
• Transmission fluid loss
• Damage to surrounding mounts
• Damage to associated drivetrain components
• Transmission malfunction
• Vehicle immobilisation
• Expensive mechanical repairs

The Fabryka 4x4 6mm aluminium guard creates a substantial barrier underneath the transmission to reduce direct exposure to these hazards.

Transfer Case Protection

The transfer case is a critical part of the Land Cruiser four-wheel-drive system and sits beneath the centre of the vehicle where it can also become exposed during serious off-road use.

Impact damage to the transfer case may affect the casing, seals or surrounding drivetrain components and can potentially compromise the vehicle's four-wheel-drive capability.

Protecting the transfer case is particularly valuable on vehicles used for remote overland travel, where drivetrain damage can leave the vehicle stranded far from conventional recovery access.

Combined Gearbox & Transfer Case Protection

This Fabryka 4x4 guard provides protection for both the gearbox and transfer case rather than covering only one drivetrain component.

The combined design extends protection across a larger area of the central underside and helps reduce exposed sections between individual drivetrain components.

This makes it particularly useful when travelling across:

• Deep wheel ruts
• Raised track centres
• Rocky trails
• Mountain tracks
• Forestry roads
• Agricultural access routes
• Remote expedition terrain

Heavy-Duty 6mm Aluminium Construction

The guard is manufactured from substantial 6mm aluminium plate.

The considerable material thickness provides strong protection while retaining important advantages associated with aluminium underbody armour.

• Strong resistance to underside impacts
• Lower weight than comparable heavy steel protection
• Excellent natural corrosion resistance
• Suitable for wet and muddy environments
• Well suited to heavily equipped touring and expedition vehicles

Precision Laser-Cut Construction

The 6mm aluminium plate is precision laser cut during manufacture.

This allows the overall profile, mounting locations and detailed sections of the protection plate to be produced accurately and consistently.

Accurate manufacture is especially important around drivetrain components where correct fitment and clearance must be maintained.

Press-Brake Formed for Strength & Fitment

After laser cutting, the protection plate is shaped using a press brake.

The formed sections allow the guard to follow the underside of the J150 drivetrain while also increasing structural rigidity compared with a simple flat sheet.

This helps the plate resist deformation and distribute impact loads across a larger area.

Hand-Finished Manufacturing

The protection plate is hand finished after the primary cutting and forming operations.

This combines precision machine fabrication with final manual finishing before the product is supplied for installation.

Protection Against Common Off-Road Hazards

The gearbox and transfer case guard helps protect the central drivetrain against common off-road hazards including:

• Rocks and exposed stone
• Deep wheel ruts
• Raised track centres
• Tree roots
• Branches
• Mud and trail debris
• Hidden obstacles during water crossings
• Forestry tracks
• Agricultural roads
• Uneven mountain trails

Build a Complete 2017-On Fabryka 4x4 Protection System

This gearbox and transfer case guard forms the central drivetrain section of the Fabryka 4x4 aluminium protection package for later Land Cruiser J150 vehicles.

• Fabryka 4x4 6mm Aluminium Engine & Sump Guard – J150 2017-On
• Fabryka 4x4 6mm Aluminium Gearbox & Transfer Case Guard – J150 2017-On – this product
• Fabryka 4x4 6mm Aluminium Fuel Tank Guard – J150 2009-On

Together, the appropriate protection plates can provide coverage beneath the:

• Engine
• Engine sump
• Gearbox
• Transfer case
• Fuel tank

Matching 2017-On Engine & Sump Guard

For the front section of the vehicle, use the corresponding later-model Fabryka 4x4 engine protection plate:

Fabryka 4x4 Aluminium Engine & Sump Guard for Toyota Land Cruiser J150 2017-On – 6mm

Combining the matching engine protection with this gearbox and transfer case guard creates substantially broader protection along the underside of the vehicle.

Matching Fuel Tank Protection

Protection can be extended farther rearwards using the Fabryka 4x4 aluminium fuel tank guard:

Fabryka 4x4 Aluminium Fuel Tank Guard for Toyota Land Cruiser J150 2009-On – 6mm

The current manufacturer application for the fuel tank guard runs from 2009 onwards, allowing it to form part of the later J150 underbody protection system.

Earlier 2009–2017 J150 Models

This OLN guard should not be selected for an earlier J150 simply because the overall vehicle platform is the same.

Fabryka 4x4 provides a separate gearbox and transfer case guard for the earlier model period:

Fabryka 4x4 Aluminium Gearbox & Transfer Case Guard – Toyota Land Cruiser J150 2009–2017 – 6mm

The correct model-year-specific protection plate should always be selected.

Earlier Engine Protection Options

Fabryka 4x4 also offers separate front protection for earlier J150 vehicles:

• 6mm Aluminium Engine & Sump Guard – J150 2009–2017
• 6mm Aluminium Engine & Sump Guard – J150 2013–2017

These should be treated as separate applications rather than alternatives for the later 2017-On engine guard.

Steel Underbody Protection Alternatives

OFM4x4 also offers steel underbody protection options for the Toyota Land Cruiser Prado 150 / J150.

• Steel Engine & Sump Guard for Toyota Land Cruiser J150
• Steel Gearbox Guard for Toyota Land Cruiser J150
• Steel Fuel Tank Guard for Toyota Land Cruiser J150

These provide a traditional steel alternative for customers who prioritise heavy-duty steel armour and are less concerned about additional vehicle weight.

4mm Aluminium Alternatives

OFM4x4 also offers lighter aluminium protection options for the Land Cruiser J150:

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

The Fabryka 4x4 product uses substantially thicker 6mm aluminium and combines gearbox and transfer case protection in one drivetrain guard.
