Dmax S3 underbody – ARB Underbody Protection for Isuzu D-Max Series 3 (2019-Onward)

ARB Underbody Protection for Isuzu D-Max Series 3 (2019-Onward)

Whether your D-Max Series 3 is a workhorse, touring rig or weekend green-laner, the underside is constantly at risk from debris, ledges and deep ruts. A properly designed ARB Dmax S3 underbody is built to take the punishment so your important mechanicals don’t have to.

Why the Dmax S3 underbody is essential

Unlike universal plates, this ARB system is built specifically around the chassis and drivetrain layout of the D-Max Series 3. Multiple pressed and folded steel panels run from the front crossmember rearwards, creating a strong, integrated shield over the sump and gearbox area. The panels follow the factory lines closely for a snug fit that minimises vibration and noise.

The Dmax S3 underbody focuses protection exactly where the D-Max Series 3 is most vulnerable, spreading impacts across strong steel surfaces so the plate takes the hit instead of your sump or gearbox.

Key benefits of ARB underbody protection

• Durable powder-coat finish to withstand UK road salt, mud and year-round weather.
• Vehicle-specific design for the – not a generic one-size-fits-all part.
• Protection for sump, gearbox and key underbody components off-road and on rough worksites.
• Heavy-duty pressed and folded steel skid plates for serious impact resistance.
• Recessed mounting hardware to help the vehicle slide over rocks, ruts and ledges.

Built for real-world off-road and work use

If you tow, work the vehicle hard or carry heavy loads, your D-Max Series 3 is already doing a big job. ARB underbody protection adds the safety margin that keeps it working, even when clearance is challenged or terrain becomes unpredictable.

Damage to an exposed sump or gearbox casing can easily run into four figures once recovery, repair and fluids are taken into account. By adding a properly engineered ARB system to your D-Max Series 3, you significantly reduce the chance of an unlucky impact turning into a very expensive breakdown.

Because ARB develops full vehicle packages, the underbody system is engineered with compatibility in mind. It sits correctly with ARB front protection and other accessories commonly fitted to serious D-Max Series 3 builds.
