Arnott SK-3888 Suspension Strut and Coil Spring Assembly - Front

Arnott SK-3888 Front Coil Strut Assembly

Arnott SK-3888 is a new front coil strut assembly for select Mercedes-Benz GLK-Class models with the X204 chassis. It replaces the original front suspension strut with a passive, OE-style design that delivers factory-like stability, handling, control, and ride comfort.

Built as part of Arnott’s Coil Strut Assembly line, this unit combines the strut, coil spring, and related support components into a single front suspension assembly for a direct replacement approach on the Mercedes-Benz GLK250, GLK300, GLK350, and GLK280.

Detailed Description

Arnott SK-3888 is engineered for the front suspension of the 2009-2015 Mercedes-Benz GLK-Class, including GLK250, GLK300, GLK350, and GLK280 applications. This passive strut assembly is built to mirror original OE performance without electronic commands, using Arnott-tested internal settings to match the ride characteristics expected from the factory setup. If you are replacing a worn Mercedes-Benz GLK350 front strut assembly or servicing a GLK300 front suspension, SK-3888 provides a complete coil strut solution in one assembly.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Part number SK-3888 is also referenced for OE-style replacement needs where the original Mercedes front strut assembly has lost damping control, developed noise, or no longer maintains proper ride height and road feel.

What It Helps Fix

• Front-end bounce or excessive body movement
• Clunking or knocking from a worn strut assembly
• Uneven ride quality on Mercedes-Benz GLK-Class front suspension
• Reduced steering response and road control
• Loss of OE-like comfort from a fatigued coil strut assembly

Installation Notes and Tips

Fits 2013-2015 Mercedes-Benz GLK250, front. Fits 2010-2015 Mercedes-Benz GLK300, front. Fits 2009-2015 Mercedes-Benz GLK350, front. Fits 2009 Mercedes-Benz GLK280, front.

Quality Assurance

Arnott manufactures this SK-3888 coil strut assembly as a new aftermarket replacement with OE-style performance targets for the Mercedes-Benz GLK-Class. The design uses a passive twin-tube hydraulic strut, gas charging, and integrated spring components to support consistent front suspension operation.
