Bring back controlled, comfortable ride quality with the Arnott Industries Suspension Strut and Coil Spring Assembly SK-3978, a pre-assembled front coil-over strut unit that drops in as a direct-fit replacement for the 2006-2011 Mercedes-Benz ML500, 2007-2009 ML320, 2007-2011 ML350, and 2008-2011 ML550. It arrives as a complete strut-and-coil-spring assembly for convenient installation, saving you from separate spring compression during the job.
Coil-over strut design: Arnott's exclusive coil-over strut is engineered to deliver the stability, handling, control, and comfort of the original OE strut without any external commands from the vehicle.
Active-to-passive conversion: Uses electronic-to-passive shock technology to convert an active suspension corner to a passive setup, with a custom-valved shock adapted to driving style.
Tuned to mimic OE: Arnott engineers determined and tested the optimal internal strut settings to mimic the OE performance.
Improved seals: Upgraded seals help prevent leaks. Engineered and assembled in the USA.
This is a front-position assembly. Arnott recommends replacing these struts in pairs for balanced ride and handling.
