VB-3267 is a new Air Suspension Solenoid Valve Block from Arnott for multiple Mercedes-Benz® models including the 2006-2018 GL-Class (X164/X166), 2006-2018 ML-Class (W164/W166), 2007-2017 S-Class (W221/W222), 2006-2013 CL-Class (W216) and 2010-2012 R-Class (W251) including 4MATIC®, AMG and Hybrids. This valve block is a direct replacement for the vehicle's failing OE valve block.An air suspension solenoid valve block distributes air from the Compressor to your Air Springs and Air Struts. Over time the valve block O-Rings can dry rot and leak air causing your compressor to overwork or allow moisture to degrade the electrical solenoid's components. This aftermarket Mercedes-Benz Solenoid Valve Block is made from the highest quality materials and is designed to meet or exceed the original equipment specifications.
