4Motion gives you traction a front-wheel-drive van driver can only envy — and that is exactly why it takes you where the factory plastic trays stop being enough. This set closes off the T6 underbody along its full length, rear differential included.

What it covers. The manufacturer lists a full 4-piece set: engine with gearbox, exhaust pipe, fuel tank and differential.

4.0 mm aluminium. Aluminium sheet, 4.0 mm thick, in a silver finish. Aluminium takes road salt in its stride and does not need its coating babied the way steel does — under a van that spends months in winter brine, that is worth something.

Installation. The plates use the factory mounting points and a complete fitting kit is supplied.

Fitment and limitation. Volkswagen T6 4WD from 2015, all versions except Euro6 — the restriction comes from the manufacturer, so check your vehicle before ordering.

• Four plates: engine with gearbox, exhaust, fuel tank, differential
• 4.0 mm aluminium, silver finish
• Fitting kit included, factory mounting points
• VW T6 4WD from 2015, not for Euro6 versions

A set for someone who treats the T6 as a travel vehicle rather than just a family van, and wants the underbody question answered once and properly.
