Range Rover L405 Long Wheelbase Electric Running Boards: Finally, the Right Length
On a long wheelbase Range Rover, standard running boards never quite fit: too short, they leave the rear door without support. This kit is specifically designed for the long wheelbase version of the Range Rover L405, with platforms that run the full length of both doors. These Range Rover L405 electric running boards deploy when the doors open and retract as soon as the door is closed, like on the highest-specification versions.
Why the long wheelbase makes all the difference with this kit
Between a standard L405 and an L405 LWB, there are an extra twenty centimetres, all located between the doors. Fitting a set of running boards designed for the short wheelbase on a long version condemns rear passengers to step out into thin air. This retractable running board for long wheelbase Range Rovers respects the actual dimension and provides a continuous support surface, from the front pillar to the rear of the passenger door.
The result, when all four doors open, is spectacular: two full-length platforms that emerge at the same time, on a car already impressive in its size. Then everything disappears, and the automatic Land Rover running board leaves no trace under the side sill.
Aluminium and polypropylene: a construction designed for permanent exposure
The manufacturer describes a set made of aluminium alloy combined with PP plastic for the trim. It is a sensible choice: the aluminium carries the load and resists corrosion, while the polypropylene absorbs gravel impacts without cracking or rusting. The set is stated to be waterproof, which is the minimum requirement for a waterproof electric running board living under the car all year round. It is secured with screws on the provided mounting points.
- Specific to long wheelbase — the platform length corresponds to the LWB version of the L405
- Automatic electric deployment — operated by opening the doors
- Aluminium and PP plastic — load carried by the metal, impact-resistant trim
- Set stated to be waterproof — designed to remain exposed under the vehicle
- Screw mounting — on existing mounting points
- Complete 2-side kit — driver and passenger sides supplied together
Fitting this kit on a Range Rover IV: technical reading before purchase
The manufacturer indicates compatibility with the Range Rover IV (L405) and the Range Rover IV SUV, from 2019 onwards. The mention of "long wheelbase" is decisive here: check the exact designation on your registration document or measure the wheelbase between your front wheel arches before ordering. Regarding installation, the installation of an electric running board on a Range Rover is carried out with the vehicle raised, with an electrical connection to the power supply and the door opening signal. It is this final step that justifies entrusting the work to a workshop if you are not accustomed to Land Rover wiring harnesses.
Does a motorised running board really last over time?
On this type of mechanism, longevity depends mainly on two things: the quality of the motor-reducer's waterproofing and the cleanliness of the joints. The manufacturer announces a two-year warranty on this reference — we report this mention as is, without replacing it. In practice, rinse the underbody after periods of road salt and visually check the axles once a year: a automatic electric running board maintained in this way keeps its smooth movement for a long time.
