Description

If you're shopping for a 2018-2021 Mazda 6 absorber to firm up a tired rear ride, the KYB Excel-G Shock Absorber (P/N 3440137) is a nitrogen gas-charged, twin-tube gas shock designed to help restore your vehicle's original ride control. It drops in as a direct-fit rear shock for the 2018-2021 Mazda 6.

Nitrogen gas-charged twin-tube design: made on KYB's OE assembly lines with OE-quality components and calibrated to restore the vehicle's designed performance, not change it — earning the OEA (Original Equipment for the Aftermarket) classification.
Triple lip fluid seal: reduces the chance of oil and gas leaking out.
Vehicle-specific damping valves: hand assembled in-house to correctly manage tire contact, steering response and body movement.
Supports electronic safety systems: helps keep the electronic safety systems that depend on the suspension, brakes and tires performing as the vehicle manufacturer intended.

Designed to help restore the original control, stability and handling of your 2018-2021 Mazda 6 if worn rear shocks are the cause of poor ride control. Sold individually; for even, balanced damping, replacing both rear shocks together as a matched pair is recommended.
