$575.00 Sale Save

Protect critical underbody components on your Toyota 4Runner or Lexus GX460 with the ARB Under Vehicle Protection Skid Plate—engineered for serious off-road use.
While bumpers and sliders protect visible panels, the most costly trail damage often occurs underneath the vehicle. ARB’s skid plate system is designed to shield vital components from rocks, ruts, and unexpected obstacles encountered during off-road driving.

Manufactured from 3mm laser-cut, pressed, and folded steel, this skid plate delivers an excellent strength-to-weight balance while maintaining high impact resistance. The design securely bolts directly to the vehicle’s chassis, providing outstanding structural integrity and reliable protection for components such as the steering system, oil pan, transmission, and transfer case.

The origins of ARB can be traced back to Australia’s remote Top End, circa 1975. A region of vast distances and rugged terrain, it was fast becoming a Mecca for the nation’s burgeoning 4WD community. However, the very environment that attracted 4 wheelers also wreaked havoc on their equipment – when driving in extreme conditions, only the best 4×4 accessories will do.

This was the conclusion drawn by Tony Brown during his travels at the time. While exploring the treasures of the Top End, the skills Tony gained from working on his Land Rover were regularly called on to mend damaged bull bars and broken roof racks. Bar work back then was crude, not at all suited to overland touring, and through this experience an idea was born – high quality equipment that met the vigorous demands of 4WD owners.

Upon returning to Melbourne, Tony put theory into practice via the family garage, where he sought to address the product deficiencies he’d encountered. His vision called for a combination of sound design principles and reliable raw materials… a simple solution to an endemic problem. The concept was embraced when it hit the fledgling 4×4 market, and ARB – the initials of Anthony Ronald Brown – was founded.
