KYB Suspension Shock Absorber P/N:3440137
Help quiet a bouncy, worn-out rear end and bring back settled body control with the KYB Excel-G shock absorber (P/N 3440119) — the shock absorber 2015-2018 Ford Mustang owners reach for when the factory dampers are done. It installs in the REAR position as a direct-fit replacement for the 2015-2018 Ford Mustang, and as an OEA (Original Equipment for the Aftermarket) unit it's calibrated to restore the vehicle's original, designed performance rather than change it.
KYB is a leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same OE assembly lines using the same OE-quality components.
If worn rear shocks are behind your excess bounce, sway, or poor rebound control, this Excel-G replaces them. Replacing both rear shocks together as a pair is recommended for balanced ride control. See the "Vehicles it fits" section for engine-level fitment.
