Product Details
KYB Excel-G is an Original Equipment for the Aftermarket solution focused on returning the vehicle to its designed damping characteristics rather than changing ride feel. For Mustang owners, this KYB shock absorber supports consistent rear suspension control on 2015, 2016, 2017, and 2018 Ford Mustang applications with the listed wheel and suspension package restrictions. The KYB 3440119 is a direct-fit rear shock choice for drivers replacing worn OE-style damping on the Ford Mustang platform.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Excessive rear bounce after bumps
- Reduced stability during braking and lane changes
- Uneven or loose rear suspension control
- Harsh or inconsistent ride response from worn shocks
- Handling drift caused by fatigued damping
Installation Notes and Tips
Compatible With 2015-2018 Ford Mustang, rear, with 17 and 18 inch wheels, without Electronic Controlled Suspension, without Performance Package.

Confirm mount style and compressed/extended length against the original part before installation.
