Arnott Industries Air Spring to Coil Spring Conversion Kit P/N:C-2956
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 Buyer's Guide tab 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.
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.
What does this kit do?
It converts the vehicle's factory air-assisted suspension to a passive coil-spring system, supplying steel coil springs, custom-valved shock absorbers, and an Electronic Bypass Module.
Does it fit front and rear?
Yes. This is a front-and-rear conversion kit, so it addresses the air-suspension components at both axles.
What vehicles does the C-3552 fit?
It is a direct-fit conversion for the 2011-2018 Porsche Cayenne. Check the Buyer's Guide tab and confirm fitment for your vehicle before ordering.
What is the Electronic Bypass Module (EBM)?
It is a patented module (U.S. Pat. No. 9,329,917) designed to eliminate dash-panel suspension error lights after the air-to-coil conversion.
Are the springs steel?
Yes. The kit uses durable steel coil springs, and it is engineered and assembled in the USA.
