The Bilstein B6 Performance front right strut assembly (MPN 35-118312) is a 36mm monotube unit sized for the front passenger-side corner of the 2006 Subaru Legacy GT. The B6 line is engineered as a step up from factory damping that keeps the original coil spring in service. Valve settings are matched to each application inside a monotube body, so the damping is calibrated to a specific chassis rather than a generic setup.
Against stock, the case rests on handling consistency and durability. Each damper is tested to meet or exceed OE standards, according to the manufacturer. Because the spring stays in place, you upgrade damping without the cost and alignment work of a coilover swap. The B6 Performance lineup carries a limited lifetime warranty. Shoppers searching for a 2006 Legacy GT front right strut, a Bilstein B6 35-118312 monotube, or a Legacy GT OE-replacement damper upgrade will find this is the part that matches those terms. Fitment is the detail to verify first. Listings disagree on which Legacy years and trims share this strut, and on whether Spec B upper mounts are needed, so check the manufacturer's application data against your VIN before ordering. Replace the left and right struts together for balanced ride and handling.
This is a strut-level job that typically calls for a spring compressor, a set of wrenches, a torque wrench, and jack stands. Work on a level surface, support the vehicle securely, and check the upper mount hardware against your car before you begin, since mount requirements vary by listing. Confirm torque values against the manufacturer's installation instructions, and get a wheel alignment after the swap.
