The Extended Flare option for the 144" Wheelbase Sprinter is available for the driver side only and is 2" deeper than our standard Flare. It is only available for the driver side because it would obstruct the slider door on the passenger side. Therefore it also doesn’t work on vans with dual slider doors or on right hand drive vehicles. The Extended Flare option does not cost more than the standard depth Flare and can be selected as a window or solid Flare.
