KYB 340113 Suspension Strut - Rear

KYB Excel-G Rear Suspension Strut

The KYB Excel-G rear suspension strut is built to restore original ride control, stability, stopping performance, lane-change response, and handling. This KYB Excel-G 340113 is an OE-style replacement for the rear suspension on select Toyota 86, Subaru BRZ, and Scion FR-S applications.

Excel-G is KYB’s OEA line, meaning it is calibrated to return the vehicle to its designed performance rather than alter it. For drivers searching for a rear strut for a 2013-2018 Subaru BRZ, 2013-2016 Scion FR-S, or 2019 Toyota 86, part number 340113 is built around factory-style control.
