The RalliTEK Bilstein B6 Assembled Strut Kit is a pre-assembled front and rear suspension kit built for the Subaru WRX (2008-2021). Each strut ships fully assembled with a genuine Bilstein B6 shock, a RalliTEK lift spring, new top hats, and mounting hardware, so there is no spring compression tool or shock swap needed at install. The B6 monotube shock is tuned for a controlled, stock-plus ride on gravel roads and rougher pavement while the RalliTEK spring adds ground clearance for all-terrain tires and winter driving. This kit spans both the 2008-2014 and 2015-2021 WRX generations, with a Standard configuration on the earlier chassis and a Trail configuration on the later chassis, so it is easy to match the correct kit to your model year. Installation uses the factory strut mounting points for a direct bolt-in fit with no special tools required, making this a practical upgrade for WRX owners who want more capability on gravel and winter roads without sacrificing everyday drivability. Canada-wide shipping from Flat 4 Offroad in Calgary.
