The RalliTEK Bilstein B4 Assembled Strut Kit is a pre-assembled front and rear suspension kit for the Subaru Outback (2015-2019) built with a genuine Bilstein B4 shock and a RalliTEK spring, ready to bolt in without any additional assembly. The Bilstein B4 is a factory-replacement monotube shock that restores original equipment ride height and handling characteristics, making this kit a straightforward option for Outback owners who want fresh, reliable suspension components rather than a lift or performance upgrade. Because the strut ships fully assembled with new top hats and hardware, there is no spring compressor or shock disassembly needed, it installs the same way the factory strut came out. This kit is a good fit for daily-driven Outbacks that need worn or leaking struts replaced with quality parts, or for owners planning a future lift who want a solid baseline before adding lift springs and a taller shock down the road. Canada-wide shipping from Flat 4 Offroad in Calgary.
