With the introduction of the Renault Master IV from 2024, a lot has changed in the commercial vehicle sector. In addition to modern engine technology, optimized aerodynamics and new electric versions, the topic of comfort and safety when getting in is also playing an increasingly important role. A key accessory for this is the side step – it makes it easier to get in and protects the driver and passengers from falls or missteps. But which design is the right one? In this article, we compare the ST series in 1,150 mm and 1,400 mm width and show which version is ideal for which application.
Why a side step makes sense for the Renault Master IV
Anyone who regularly travels with tools, materials or luggage knows this: Getting into vans with a high floor is often difficult. Especially in vehicles with a high body (H2 or H3), stepping inside is not only uncomfortable, but can also be a tripping hazard. This is where the side step of the ST series offers a simple and durable solution.
The step is permanently mounted on the vehicle body and can be used at any time without the need for actuation, extension or maintenance. It creates a stable, safe step and ensures that daily access is child's play. This pays off in terms of ergonomics and efficiency, especially in commercial applications where employees frequently get on and off the vehicle.
The ST series at a glance – robust, maintenance-free and vehicle-specific
The ST series is specially designed for commercial vehicles such as the Renault Master IV. It is made of robust, galvanized steel or stainless steel and is completely resistant to corrosion. As there are no moving parts, it is maintenance-free and remains fully functional even after years of use. The textured surface offers a secure grip even in rain, snow or ice - a clear safety advantage in everyday working life.
The ST series is available in two widths: 1,150 mm and 1,400 mm. Both variants are compatible with the current Renault Master IV models, whether with front, rear or electric drive.
Fitting vehicle variants of the Renault Master IV (from 2024)
Both step variants are matched to the dimensions of the latest Master generation. The following table shows the most important vehicle dimensions at a glance:
| Designation | Drive | Wheelbase | Total length | Vehicle height |
|---|---|---|---|---|
| L2H2 | FWD / electric | 3,582 mm | 5,685 mm | 2,498 mm |
| L3H2 | FWD / electric | 4,215 mm | 6,315 mm | 2,498 mm |
| L3H3 | FWD / electric | 4,215 mm | 6,315 mm | 2,778 mm |
| L4H3 | RWD / electric | 4,215 mm | 7,075 mm | 2,778 mm |
The steps can be fitted to specific vehicles and are suitable for vehicles with double doors as well as for models with a tailgate. Optionally available trim strips can additionally widen the tread surface and compensate for the overlap of the original plastic sills.
Comparison: ST series 1,150 mm vs. 1,400 mm
Both variants of the ST series have a similar technical design, but differ in their width and therefore their area of application. While the 1,150 mm version offers a compact, space-saving solution, the 1,400 mm version is ideal for vehicles with a wide entrance door or frequent multi-person access.
| Property | ST series 1,150 mm | ST series 1,400 mm |
|---|---|---|
| Length | 1,150 mm | 1,400 mm |
| step depth | 220 mm | 220 mm |
| Carrying capacity | 150 kg | 150 kg |
| Material | Valvanized steel or stainless steel | Valvanized steel or stainless steel |
| Mounting | Vehicle-specific, fixed at the side | Vehicle-specific, fixed at the side |
| Advantage | Compact & unobtrusive | Large footprint over the entire door opening |
Which variant suits which application
1,150 mm version: This version is ideal for vehicles that are only occasionally accessed via the side doors or where space and weight are important. Thanks to its compact design, it blends harmoniously into the vehicle design without protruding excessively. Ideal for delivery services, maintenance vehicles or assembly operations with frequent entry and exit of individuals.
1,400 mm version: The wider step is recommended for vehicles with intensive use of the side door, such as tradesmen's vans or people carriers. It provides easy access for two people at the same time and offers additional support when loading tools, boxes or equipment. The larger surface area allows you to step safely even in inclement weather - a real plus in terms of comfort.
Installation and maintenance – simple, quick and durable
The ST steps are fitted directly to the body of the Renault Master IV using vehicle-specific brackets. The required installation material is included in the scope of delivery. After installation, the steps are maintenance-free as there are no moving parts. Occasional cleaning is all that is needed to remove dirt and road salt and extend the service life.
Depending on the design, an individual technical approval may be required if no vehicle-specific certificate is available. This should be agreed with a testing organization such as TÜV or DEKRA before installation.
Practical advantages of the ST series at a glance
- Non-slip surface for maximum safety
- Maintenance-free construction – no moving parts
- High load capacity of up to 150 kg
- Weatherproof thanks to galvanized steel or stainless steel

Conclusion: More safety and comfort with the right step
Whether 1,150 mm or 1,400 mm – the side steps of the ST-Series offer the highest level of functionality, safety and stability. They make everyday work easier, make access more comfortable and significantly increase safety. Thanks to their robust design and simple installation, they are the ideal retrofit solution for all Renault Master IV models built from 2024 onwards.
For those who often enter via the side doors or use the van for manual work, the wider 1,400 mm version is particularly beneficial. The 1,150 mm version is the perfect choice for more compact inserts or vehicles with limited space requirements. In any case, the ST series is an accessory that pays off in the long term - thanks to greater comfort, safety and durability.
