What does 'OE Replacement (Air)' mean for this strut?

OE Replacement (Air) means this strut is designed to directly replace the original air suspension strut on your vehicle. Bilstein is an original equipment supplier, so this part is built to match the quality and function of the factory part.

Do I need any special tools or modifications to install this strut?

No, this Bilstein B4 OE Replacement Air Strut is designed for a direct connection to the original connectors on your Porsche Cayenne. This means installation should be modification-free, using your vehicle's existing wiring and air lines.

Should I replace both rear air struts at the same time?

While this part is for the rear right side, it's often recommended to replace air suspension components in pairs. This helps ensure consistent performance and ride height between the left and right sides of the vehicle.

About this part

Product Details

Bilstein is a well-known name for suspension components, especially for European vehicles, and they are an original equipment supplier for many air suspension systems. This Bilstein B4 OE Replacement Air Strut is specifically made to replace the rear right air strut on your 2011-2018 Porsche Cayenne. If your Cayenne's air suspension is feeling saggy or uneven, this part is designed to bring back that original ride height and comfortable feel.

This strut is built with 100% new parts, ensuring it meets or even exceeds the quality standards set by Porsche for your Cayenne's original air suspension. It's designed to connect directly to your vehicle's factory wiring and air lines, meaning you won't need to make any modifications for installation. This direct-fit approach helps restore the original functionality and the comfortable ride quality you expect from your Cayenne.

When you're replacing an air strut, it's often a good idea to inspect the other side as well, as air springs can wear over time. This strut is designed to be a direct replacement, so you can be confident in its ability to restore your vehicle's original performance and comfort.
