Mercedes-Benz CLA W117 parts
The W117 is the sedan variant of the CLA, recognizable by its more classic profile within the Mercedes-Benz compact lineup. Whether you want to refine the rear end of your vehicle or simply find the right Mercedes-Benz CLA W117 part, the catalog available here guides you to the accessory that matches your exact generation.
Refining the rear end of your CLA W117
The rear diffuser is one of the parts that most effectively changes the appearance of the rear end on a compact like the CLA W117. Fitted under the bumper, it visually structures the exhaust outlets and gives the whole a sportier character, in the spirit of AMG builds that have always paid close attention to the lower rear finish.
On a sedan with relatively understated lines like the W117, this addition can be enough to transform the silhouette without touching the rest of the bodywork or disrupting the vehicle's visual balance.
Choosing the right rear diffuser for your W117
The Mercedes-Benz CLA W117 parts catalog is currently centered on the rear diffuser. Before ordering, compare your vehicle's original bumper carefully with the photos and information on the product page: bumper variants depending on standard equipment can affect the exact fit of the part.
The W117 shares certain structural elements with the C117, but exterior surfaces are not systematically interchangeable between the two body styles. Your chassis code, shown in field E of your registration document, remains the most reliable reference to confirm compatibility before placing any order.
How do you verify that a rear diffuser is compatible with my CLA W117?
The compatibility of a rear diffuser depends first and foremost on the bumper version fitted at the factory on your vehicle, which can vary based on options selected or mid-cycle updates. Check your vehicle generation before ordering: if the stated compatibility is wrong, return shipping is on us and you get a full refund.
Returns possible within 30 days if the part does not suit you.
