Help restore controlled, confident handling with the KYB shock absorber 3440133, an Excel-G gas shock that drops in as a rear direct-fit replacement for the 2019-2025 Mazda 3. Part of KYB's OEA (Original Equipment for the Aftermarket) line, the Excel-G is built on the same KYB OE assembly lines with OE-quality components and is calibrated to restore the vehicle's original designed performance, not change it.
Signs a shock may need replacing include excessive bounce, nose dive, body sway, or reduced stability during lane changes and stops. Sold individually; replacing both rear shocks together is recommended for balanced ride control.
