SK-3842 is a brand new Arnott aftermarket coilover stut manufactured for the front right side of the 2009-2016 Audi A4/A4 Quattro (B8) and the 2008-2016 A5/A5 Quattro. This passive strut design delivers the stability, handling, control and comfort of the original OE strut without any external commands from the vehicle. Arnott engineers have determined and tested the optimal internal strut settings to mimic the OE performance. This passive strut is for vehicles not equipped with adaptive dampers.
