Product Details
KYB Excel-G is KYB’s Original Equipment for the Aftermarket line, built for drivers who want the vehicle to respond like it did from the factory. The 3340340 suspension strut uses the same manufacturing approach and quality component standards found in KYB OE production, making it a direct-fit choice for restoring suspension performance on the Mazda 3. If you are replacing a worn front right strut on a 2019-2023 Mazda 3 or a 2024-2025 Mazda 3 except Mexico-built models, this part number provides the correct OE-style replacement profile.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Excessive bouncing after bumps
- Reduced steering response during lane changes
- Uneven or unstable front-end control
- Longer stopping feel caused by worn suspension damping
- Harsh or inconsistent ride quality from a failing strut
Installation Notes and Tips
Fits 2019-2023 Mazda 3, front right. Fits 2024-2025 Mazda 3, front right, except Mexico-built vehicles. Verify the upper mount thread size and vehicle build details before installation. Because this is a suspension strut, professional installation and a post-repair alignment are recommended after replacement. Confirm the existing strut matches the listed compressed length, extended length, and stroke length before ordering.
