The Underbody Protection - 1st Plate (part number BP031-1) is a underbody protection plate engineered for Navara D40 ST-X/ST V6/2.5L. Manufactured by Roadsafe, one of Australia's longest-standing 4WD steering and suspension specialists, it is a direct-fit part for the listed vehicles.
Roadsafe 4WD Protection Plates are manufactured from 3mm steel, zinc coated for longevity. Protection Plates perfectly integrates with the vehicle key underbody designs with carefully positioned water dispersion and venting holes. The Roadsafe 4WD Protection Plates protect the key under-car components without compromising airflow, water disbursement or durability. Offroad driving exposes the vehicle to damage from a huge variety of obstacles found on the tracks, from rocks to logs.  Roadsafe 4WD protection plates protect the vehicle undercarriage from the majority of bumps and scrapes against these obstacles. 
Protection Plates are especially useful in vehicles with IFS or general low ride height. Protection Plates are manufactured from 3mm steel, ensuring that while tough, the plates are not too heavy or rigid to contribute to structural damage to the vehicle in the event of a heavy impact.

Roadsafe 4WD Protection Plates are Australian designed & made. Manufactured in 3mm steel and very strong, Roadsafe 4WD protection plates are zinc coated for longevity and laser cut for precision. Plates can be painted or powder-coated over the zinc treatment by the customer if required (we do not paint!). All plates use the original bolt pattern – no drilling required. Where bolts/nuts are required for fitment, they are supplied with the kit. We recommend the use of a thread locker during the installation & tightening of all nuts/bolts. Easy bolt-on installation. High tensile hardware. No welding or drilling is required. Pressed ribs and folded reinforcements have been included to provide significant strength without adding unnecessary weight to the vehicle.
Where possible, oil change access, without plate removal, has been integrated into the plate design.
Under Body Protection Plate Application Guide
RAP32A General Under Body Protection Plate Information Bash Plate compatible with Nissan Navara D40 (St-X & St) 2012-2013 V6 & 2.5L - 1st Plate
The most vulnerable components under a touring 4WD — radiator lines, sump, steering, transmission and transfer case — sit low and forward, exactly where rocks, ruts and stumps strike first. Factory splash guards are thin pressed steel or plastic designed for road debris, not impacts. A proper bash plate spreads impact loads across its area and slides the vehicle over obstacles instead of hooking them.
Roadsafe underbody protection is vehicle-specific: each plate follows the contours of the area it protects, uses the manufacturer's mounting points, and is numbered by position (1st, 2nd, 3rd plate) so you can build coverage progressively from the front bumper back.
Suits: Navara D40 ST-X/ST V6/2.5L. Please match your vehicle's generation and build date against the listing before ordering — if you are unsure, contact us with your vehicle details and we will confirm fitment.
