Fitment Guide
MODEL: Mercedes Sprinter
YEAR: 2007+
WHEELBASE: 144" and 170"/170" EXT
POSITION: Passenger Side Rear Quarter
On 2007+ Sprinter 144" wheelbases, VWD recommends installing the passenger side bump out only when the passenger side sliding door has a bond-in half-slider or fixed window, such as these VWD models:
- SR101-F (Fixed)
- SR101-SE (Half Slider)
- SR101-SER (Half Slider)
Other brands' windows in the same styles are also compatible.
On 2007+ Sprinter 170" wheelbases, the VWD passenger side bump out is currently compatible with any window in the passenger side sliding door. Contact us to confirm if you are unsure before purchasing.
T-vent handle windows, or windows with a "proud" blind or bug screen in the passenger sliding door, can scratch the exterior of the bump out. Examples that are not compatible: FW625R, SR101-AW, and SR101-DS.
Note: An awning bunk window is not recommended for passenger side 144" wheelbase Sprinters because of the risk of contact and breakage from the passenger side sliding door. It is also not recommended for passenger side 170" wheelbase Sprinters when windows are installed in the 2nd row.
