Bring settled, factory-calibrated ride control back to the rear axle with the KYB Excel-G gas-charged shock absorber (P/N 3440014). This KYB shock absorber installs as a direct-fit rear replacement for the 2014-2017 Mazda 6 and 2019-2023 Mazda CX-5, and is calibrated to restore each vehicle's originally designed damping rather than change it.
The KYB Excel-G is a nitrogen gas-charged, twin-tube shock absorber that carries the same quality components KYB builds into its global OEM products, earning it the OEA (Original Equipment for the Aftermarket) classification. It's a KYB-recommended OEM replacement shock, so if worn rear shocks are behind a bouncy or loose ride, this unit is designed to help bring back the control, stability and handling engineered into the vehicle from the factory.
- Twin-tube, nitrogen gas-charged: a gas shock absorber assembled on the same KYB OE lines using OE-quality components.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand-assembled in-house to manage tire contact, steering response and body movement.
- Supports electronic safety systems: helps keep the suspension working as the manufacturer intended so electronic safety systems perform as designed.
Sold individually; replacing both rear shocks together as a matched pair is recommended for balanced ride control.
