Front Rear Air Spring to Coil Spring Conversion Kit for 2011-2018 Porsche Cayenne - Arnott C-3552

Ditch the costly, leak-prone air suspension and put your ride on reliable coil springs with the Arnott Air Spring to Coil Spring Conversion Kit C-3552 (also written C3552). This complete front-and-rear kit is a direct-fit conversion for the 2011-2018 Porsche Cayenne — see the "Vehicles it fits" section for engine-level applications. It supplies everything needed to swap the factory air-assisted setup over to a passive coil-spring system, converting active suspension to passive operation.

• Model-specific components: includes custom-valved shock absorbers and steel coil springs matched to the vehicle for its ride quality.
• Durable steel springs: the kit uses steel coil springs in place of the air springs.
• Electronic Bypass Module (EBM): a patented module (U.S. Pat. No. 9,329,917) designed to eliminate dash-panel suspension error lights after the conversion.
• Engineered and assembled in the USA.

Because it addresses front and rear positions together, the kit replaces the air-suspension components across both axles. If failing or leaking air springs are the cause of a sagging ride or a suspension warning, this conversion swaps them for a passive coil-spring design.
