Introduction: Why Side Steps Matter for Your G63
The Mercedes-Benz G-Class is iconic for its towering ground clearance and boxy silhouette. But with great height comes a practical challenge: getting in and out. Factory side steps on the G63 and G500 offer basic functionality, but aftermarket running boards open up a world of enhanced accessibility, aggressive styling, and additional body protection. Based on our experience supplying G-Class parts to over 500 customers since 2019, upgrading your side steps is one of the most impactful modifications you can make for daily usability.
Types of G63 Side Steps and Running Boards
There are three main categories of aftermarket side steps for the Mercedes G-Class. Each serves a different purpose and suits different driving styles.
Power Deployable Running Boards
Power side steps automatically extend when you open the door and retract under the chassis when closed. These are the most premium option, offering a clean factory look when not in use. Most power step kits for the G63 and G500 feature aluminum construction with anti-slip rubber pads and LED courtesy lights. Installation typically takes 3-5 hours and requires tapping into the vehicle CAN bus system for door-sensing functionality. Prices range from $1,200 to $2,500 depending on brand and finish options.
Fixed Running Boards
Fixed side steps remain permanently in place. They are more affordable and offer greater durability for off-road use. G63 fixed running boards are commonly made from steel, aluminum, or carbon fiber. Steel options are the most rugged, with weight capacities exceeding 500 lbs, while aluminum variants offer a balance of strength and weight savings. Fixed boards are simpler to install, usually requiring 1-2 hours with basic hand tools. Most kits use existing mounting points on the G-Class chassis with no drilling required. Price range: $250 to $800.
Nerf Bars
Nerf bars are round or oval tubes that serve as both a step and a rock slider for off-road protection. They are particularly popular among G-Class owners who take their vehicles off the pavement. Nerf bars for the G63 and G500 typically feature 3-inch diameter steel tubing with a textured powder-coated finish. They provide excellent protection against trail debris and rocks. Installation is straightforward with bracket kits that bolt directly to the frame. Price range: $400 to $900.

Compatibility: W463 vs W464 vs W465
G-Class side steps and running boards are not one-size-fits-all. The W463 generation (1990-2018) has a different chassis width and mounting configuration compared to the W464/W463A (2019-2024) and the latest W465 (2025+). Always verify that the running board kit you choose specifically mentions compatibility with your G-Class generation. Most aftermarket manufacturers now produce separate part numbers for pre-2019 and post-2019 models. A W464 kit will NOT fit a W463 without significant modification. Based on our sales data, approximately 40% of return requests for side steps come from generation misidentification.
Installation Considerations
Installing side steps on your G63 or G500 is a moderate DIY project for those comfortable with basic hand tools. Here are the key considerations:
- Tools Required: Socket set (10mm, 13mm, 15mm), torque wrench, jack stands, trim removal tools
- Mounting Points: Most G-Class models have pre-drilled mounting points along the rocker panel, making alignment straightforward
- Torque Specs: Factory recommended torque is 50-60 ft-lbs for main mounting bolts
- Wiring (Power Steps): CAN bus integration requires connecting to the door control module. Professional installation recommended
- Weather Protection: Apply anti-seize compound to all bolt threads to prevent corrosion, especially in salt-belt regions

Frequently Asked Questions
Will side steps affect my G63’s off-road performance?
Fixed running boards and nerf bars can slightly reduce ground clearance but provide rocker panel protection. Power steps retract completely, offering no clearance penalty when off-roading.
Can I install side steps myself?
Fixed running boards are DIY-friendly (1-2 hours). Power steps are more complex due to wiring and typically require professional installation.
Do side steps fit all G-Class models?
No. W463, W464/W463A, and W465 models have different mounting configurations. Always confirm your model year before purchasing.
What is the weight capacity of G-Class running boards?
Fixed boards typically support 500+ lbs. Power steps support 350-400 lbs. Both are sufficient for everyday use.
