4mm Aluminium Engine & Sump Guard for Toyota Land Cruiser Prado 150 J150 2009–2023

This heavy-duty 4mm Aluminium Engine & Sump Guard is designed to protect the engine, sump, lower radiator area and vulnerable front underside of the Toyota Land Cruiser Prado 150 / J150 manufactured between 2009 and 2023.

Manufactured from substantial 4mm aluminium plate, this guard provides strong protection against rocks, deep ruts, raised ground, branches and other obstacles encountered during off-road driving while keeping additional vehicle weight lower than a comparable heavy-duty steel protection system.

The main protection shield is manufactured from aluminium, while the mounting brackets are made from steel to provide secure attachment to the vehicle. External aluminium reinforcement sections increase resistance to impact and deformation, and the complete assembly is powder coated for additional corrosion protection.

This combination makes the guard particularly well suited to overland, touring and expedition builds where strong underbody protection is required but controlling overall vehicle weight remains important.

Vehicle Compatibility: Toyota Land Cruiser Prado 150 / J150 2009–2023

Engine Compatibility: All engine variants

Important Service Information: This aluminium guard does not include an oil sump service opening, so removal may be required for some routine maintenance procedures.

Technical Overview

4mm Aluminium Front Underbody Protection

The use of 4mm aluminium plate provides substantial front underbody protection while helping keep additional vehicle weight lower than a comparable steel protection system.

This is particularly valuable on Prado 150 builds already carrying additional equipment such as:

• Steel front bumper and winch
• Roof rack and rooftop tent
• Recovery equipment
• Camping and expedition equipment
• Auxiliary fuel or water storage
• Suspension upgrades
• Larger off-road wheels and tyres

When several accessories are fitted to the same vehicle, reducing unnecessary weight in individual components can make a meaningful difference to the overall build.

Why Protect the Engine and Sump?

The engine sump and front underside are among the first mechanical areas exposed when the Prado 150 encounters deep ruts, rocks, raised ground, tree roots and hidden trail obstacles.

A direct strike to the sump can cause deformation, cracking or oil loss. Continued engine operation following severe oil loss can result in major engine damage.

A dedicated underbody guard creates a protective barrier between the terrain and these vulnerable mechanical components, helping absorb and distribute impacts before they reach the engine directly.

Protects More Than Just the Sump

Although commonly described as a sump guard, this aluminium protection plate provides broader front underbody coverage.

The protection area includes:

• Engine underside
• Engine sump
• Lower radiator area
• Front underbody components
• Lower front protection zone

This makes the front guard the foundation of the Prado 150 aluminium underbody protection system.

Aluminium Shield with Steel Mounting Brackets

The main protection plate is manufactured from aluminium while the mounting brackets are manufactured from steel.

This combination allows the impact surface to benefit from aluminium's lower weight and excellent corrosion resistance while maintaining strong steel attachment points where the guard connects to the vehicle.

Screws, nuts, clips and all required fastening accessories are supplied with the guard.

External Aluminium Reinforcement

The exterior of the protection plate incorporates additional aluminium reinforcement sections designed to increase rigidity and resistance to deformation.

These reinforcements help distribute impact loads across a larger section of the guard rather than concentrating force at a single point.

This makes the protection plate suitable for vehicles that regularly encounter rocks, ruts and rough terrain.

Complete Prado 150 Aluminium Protection System

This front guard can be combined with the matching 4mm Aluminium Gearbox Guard to extend protection further underneath the vehicle.

• 4mm Aluminium Engine & Sump Guard – Prado 150 J150
• 4mm Aluminium Gearbox Guard – Prado 150 J150

Important: The matching aluminium gearbox guard cannot be mounted without this aluminium engine & sump guard. This front guard is a mandatory component of the aluminium gearbox protection installation.

Steel Protection Alternatives

Prado 150 owners who prefer traditional heavy-duty steel protection can choose from the matching steel range.

• Steel Engine & Sump Guard – Prado 150 J150
• Steel Gearbox Guard – Prado 150 J150
• Steel Fuel Tank Guard – Prado 150 J150

This gives owners the flexibility to select the most suitable material for each build rather than being limited to a single type of underbody armour.

Aluminium vs Steel Underbody Protection

Neither material is automatically the best choice for every vehicle. The correct option depends on terrain, vehicle payload and the importance of reducing additional weight.

Important Oil Service Information

This aluminium engine guard does not include an oil sump service opening.

The protection plate may therefore need to be removed for some routine maintenance procedures, including engine oil servicing depending on the specific engine configuration.
