KYB Suspension Shock Absorber P/N:3440137
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 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. Replace shocks as an axle pair for balanced ride control. See the Buyer's Guide tab for engine-level fitment.
Does this KYB shock fit my Ford Mustang?
Yes — this Excel-G shock absorber (P/N 3440119) is a direct-fit replacement for the 2015-2018 Ford Mustang. Check the Buyer's Guide tab to confirm engine-level fitment for your vehicle.
What position does this shock install in?
It installs in the rear position on the listed applications. Confirm your setup against the Buyer's Guide tab before ordering.
What type of shock is the KYB Excel-G?
It's a nitrogen gas-charged, twin-tube design built on KYB's OE assembly lines with OE-quality components, classified as OEA (Original Equipment for the Aftermarket).
What does the triple-lip fluid seal do?
The triple-lip fluid seal reduces the chance of oil and gas leaking out of the shock, helping it hold its designed damping performance.
Should I replace both rear shocks together?
It's best practice to replace shocks as a matched axle pair for balanced, even ride control. This listing is for one shock; order two for a complete rear pair.
