Continental Engineering: The Continental OE Cabin Air Spring Advantage

This Continental OE Cabin Air Spring (Automann Part # 569.CT67638) is engineered for long-haul durability. This sleeve-style air bag maintains the precise cabin height and stability necessary for safe vehicle operation on the interstate. Note: While primarily focused on the modern Cascadia platform, this spring also services compatible Western Star applications. It features a high-grade rubber compound resistant to ozone, extreme Midwest temperatures, and corrosive road chemicals, providing the exact same fit and finish as the factory-installed part.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize OE suspension components that reduce driver fatigue. Serving as a direct professional-grade replacement for Goodyear 1S5-175, Firestone 7205, and Freightliner 18-73178-000, this air bag is built to handle the rigorous demands of modern Class 8 transport. Because cabin air springs typically wear at the same rate, replacing them in pairs is highly recommended to ensure a level cab and balanced suspension response.
