Product Description

The KYB 3410031 is an Excel-G nitrogen gas-charged twin-tube rear strut for the 2015-2019 Subaru Outback AWD. The same part number covers both the rear left (driver) and rear right (passenger) positions - purchase two for a complete rear axle replacement. This is a bare strut; the coil spring, strut mount, bearing plate, and insulators are not included and must be reused or purchased separately. All installation hardware (washers, bushings, nuts) is included; factory mounting bolts are reused. Shock boots are sold separately. For the front struts on the same platform, see KYB 3340132 (front right) and 3340133 (front left).

The Excel-G carries the OEA (Original Equipment for the Aftermarket) classification - built on the same KYB global OE assembly lines with the same components and processes used in Subaru production, calibrated specifically to restore the 2015-2019 Outback's original handling and control characteristics. KYB is Subaru's OE supplier, making the Excel-G the factory-equivalent replacement choice for this platform. The nitrogen gas-charged twin-tube design prevents hydraulic oil aeration for consistent, fade-free damping response, and vehicle-specific damping valves are hand-assembled in-house to precisely match the suspension tuning of the fifth-generation Outback. KYB's thickest and strongest strut bodies and brackets in the industry minimize flex to maintain correct alignment geometry throughout service. Backed by KYB's Lifetime Warranty to the original purchaser.
