SK-3262 is an Arnott remanufactured OE rear shock absorber for the left or right side of the 2006-2013 Mercedes R-Class (W251 Chassis) w/AIRMATIC and ADS with 4MATIC or RWD, excl AMG. The OE shock is inspected, steam cleaned, and spin blasted to bare metal before it is recharged with new high performance shock oil. Worn components, such as the piston, rod guides and seal pack are replaced before being repainted with corrosion inhibiting paint. The shock and damping coil are dyno and functionally tested to assure OE performance. Arnott remanufactures and assembles this shock in the USA.
