Arnott now offers completely rebuilt OE front air struts for Mercedes-Benz vehicles. Each aftermarket strut for the Mercedes is painstakingly disassembled and rebuilt from the ground up. Arnott has worked directly with one of the largest seal manufacturers to design and test a nearly indestructible polyurethane seal you can expect to last for many years. The price per strut at your local dealership is a small fortune! Once again, the Arnott design is not only more efficient, it's also much more affordable! Each strut is backed by a Limited Lifetime Warranty.
