Bilstein's B4 OE Replacement shocks match the factory shock's original specification and twintube internal construction, restoring a worn rear end to the way it rode when new. This is the rear shock absorber for the Volvo S60, S80, and V60, a direct OE-spec replacement rather than a performance upgrade. If the factory rear shock has worn out and you want your Volvo to ride the way it did originally, this is the restoration-grade part built for that job. Features Twintube internal design, matching the factory construction Eye lower mount (14.2mm), stem upper mount What's Included Rear Shock Absorber Installation Notes This shock is sold individually; two are needed for a complete rear axle.
