Vehicle Compatibility

Important Engine & Transmission Compatibility

This gearbox guard is not a universal Toyota Land Cruiser 100 protection plate.

This Fabryka 4x4 OLE version is specifically designed for:

• Toyota Land Cruiser 100 / J100
• 1998–2007 models

Technical Overview

Heavy-Duty Manual Gearbox Protection

The manual gearbox is a critical and valuable drivetrain component underneath the Toyota Land Cruiser 100 and can become exposed when the vehicle is driven across difficult terrain.

Rocks, deep ruts, raised centre sections and hidden obstacles can make direct contact with the transmission underside. A severe impact may damage the gearbox casing or surrounding components and could result in lubricant loss, transmission problems or expensive repairs.

This Fabryka 4x4 aluminium gearbox guard creates a substantial protective barrier beneath the manual transmission, helping reduce the risk of direct impact damage.

6mm Aluminium Construction

The gearbox guard is manufactured from substantial 6mm thick aluminium plate.

The considerable thickness provides robust protection while retaining the advantages that make aluminium particularly suitable for touring and expedition vehicle armour.

• Strong resistance to underside impacts
• Lower weight than comparable heavy steel armour
• Excellent natural corrosion resistance
• Suitable for muddy, wet and exposed environments
• Well suited to overland and expedition vehicle builds

Precision Laser-Cut Construction

The aluminium protection plate is precision laser cut during production.

This allows the overall profile, edges and mounting areas to be produced accurately and consistently, helping the guard fit correctly around the J100 manual drivetrain.

Press-Brake Formed & Hand Finished

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

The guard is then hand finished as part of the production process.

This combination of precision fabrication and manual finishing produces a vehicle-specific protection plate developed around the diesel manual Toyota Land Cruiser 100 drivetrain.

Designed Specifically for Diesel Manual J100 Models

The shape, position and mounting arrangement of the gearbox differs between Land Cruiser 100 drivetrain configurations.

Fabryka 4x4 therefore produces different gearbox guards for:

• Diesel manual
• Diesel automatic
• Petrol automatic

This OLE gearbox guard is specifically for diesel manual models and should not be substituted for either automatic transmission version.

Pair with the Diesel Manual Transfer Case Guard

For broader drivetrain protection, this gearbox guard can be combined with the matching Fabryka 4x4 aluminium transfer case guard for diesel manual J100 models.

• 6mm Aluminium Gearbox Guard – Diesel Manual – this product
• 6mm Aluminium Transfer Case Guard – Diesel Manual

Using both guards provides dedicated protection beneath the manual gearbox and transfer case instead of leaving one drivetrain section exposed.

Add Aluminium Engine & Sump Protection

Protection can be extended towards the front of the vehicle using the matching Fabryka 4x4 aluminium engine and sump guard.

Combining the correct engine, gearbox and transfer case protection plates creates a substantially broader aluminium underbody protection system.

Diesel Manual Aluminium Protection Package

For a diesel manual Toyota Land Cruiser 100 / J100, the matching Fabryka 4x4 aluminium protection combination is:

• 6mm Aluminium Engine & Sump Guard
• 6mm Aluminium Gearbox Guard – Diesel Manual
• 6mm Aluminium Transfer Case Guard – Diesel Manual

Together, these components provide dedicated protection beneath the:

• Engine
• Engine sump
• Manual gearbox
• Transfer case

Diesel Automatic Protection Options

Diesel automatic Land Cruiser 100 models require their dedicated automatic transmission protection plates:

• Fabryka 4x4 Aluminium Gearbox Guard – Diesel Automatic

• Fabryka 4x4 Aluminium Gearbox Guard – Petrol Automatic
• Fabryka 4x4 Aluminium Transfer Case Guard – Petrol Automatic

Steel Underbody Protection Alternatives

For Land Cruiser 100 owners who prefer traditional steel underbody armour, OFM4x4 also offers dedicated steel protection products.

• Steel Engine & Sump Guard for Toyota Land Cruiser J100 1998–2008
• Steel Gearbox Guard for Toyota Land Cruiser J100 1998–2008
