Vehicle Compatibility

Technical Overview

6mm Aluminium Gearbox Protection

At 6mm thick, the OCF is a substantial aluminium skid plate designed for genuine off-road protection rather than lightweight cosmetic underbody coverage.

The aluminium plate provides the rigidity required to resist impacts from rocks, raised ground, trail obstacles and deep ruts while keeping additional vehicle weight lower than an equivalent heavy-duty steel guard.

This balance of strength and weight makes the OCF particularly suitable for modified Prado 90 builds where several protection components, recovery accessories and touring upgrades may already be fitted.

Why Protect the Gearbox?

The gearbox sits along the central underside of the vehicle and can become vulnerable when crossing rocky terrain, deep ruts, uneven ground and obstacles that contact the centre of the chassis.

A direct strike to the gearbox casing can lead to cracking, fluid loss and drivetrain failure, potentially immobilising the vehicle in difficult or remote terrain.

A dedicated gearbox guard places a strong protective barrier beneath the transmission, helping absorb and distribute impacts before they reach the gearbox casing directly.

Protection for Technical Off-Road Terrain

The short-wheelbase Prado 90 is particularly capable in technical terrain, but increased off-road capability also means the vehicle may encounter obstacles that would rarely be experienced during normal road driving.

Gearbox protection becomes particularly valuable when driving over:

• Rocky tracks
• Deep cross-axle ruts
• Raised centre sections
• Tree roots
• Uneven mountain trails
• Hidden obstacles during water crossings
• Forestry and agricultural tracks

Precision Manufactured for the Prado 90

Fabryka 4x4 manufactures the guard from 6mm aluminium using precision laser cutting followed by press-brake forming and hand finishing.

The formed design improves structural rigidity while allowing the plate to follow the underside profile required for the Prado 90 / J90 SWB chassis.

This is a vehicle-specific gearbox protection plate, not a universal skid plate adapted across multiple vehicles.

J90 SWB Specific Fitment

This listing is specifically for the Toyota Land Cruiser Prado 90 / J90 Short Wheelbase.

• J90 Short Wheelbase (SWB): Compatible
• J95 Long Wheelbase (LWB): NOT compatible

Although the J90 and J95 belong to the same Land Cruiser 90 Series family, their different wheelbases affect the underbody layout and protection requirements.

For that reason, J90 and J95 protection products are listed separately on OFM4x4.CO.UK to make vehicle selection clearer and reduce the risk of incorrect fitment.

Aluminium vs Steel Gearbox Protection

Both aluminium and steel can provide effective drivetrain protection, but heavy-gauge aluminium offers important advantages for touring and expedition vehicles.

• Lower weight than comparable heavy-duty steel armour
• Excellent natural corrosion resistance
• 6mm material thickness provides substantial protection
• Reduced unnecessary vehicle weight
• Well suited to multi-piece underbody protection systems
• Ideal for touring and expedition builds

When an engine guard, gearbox guard, rock sliders, bumpers and recovery equipment are all fitted to the same vehicle, controlling the weight of individual components becomes increasingly important.

Complete Prado 90 Underbody Protection

The OCF gearbox guard is designed to complement the matching Fabryka 4x4 OCE 6mm Aluminium Engine Guard, allowing protection to extend from the front engine area further along the underside of the vehicle.

• Fabryka 4x4 6mm Aluminium Engine Guard – Prado 90 J90 | OCE
• Fabryka 4x4 6mm Aluminium Gearbox Guard – Prado 90 J90 | OCF

The OCE protects the engine, sump and front underbody, while this OCF gearbox guard provides additional protection further rearward around the transmission.

Ideal for Off-Road, Touring & Expedition Use

The Prado 90 SWB combines a relatively short wheelbase with Toyota's robust four-wheel-drive drivetrain, making it a popular platform for recreational off-roading and expedition builds.

The Fabryka 4x4 gearbox guard is particularly suitable for vehicles used for:

• Green-laning
• Technical off-road driving
• Rocky tracks and uneven trails
• Overland travel
• Expedition builds
• Forestry tracks
• Muddy terrain and deep ruts
• Mountain and remote roads
• Water crossings with hidden obstacles
• Working and utility 4x4 applications
