Bring back the factory ride and handling of your 2016-2018 Mazda CX-9 with the KYB Excel-G shock absorber (P/N 3440112), a rear-position gas shock built to restore the vehicle's original ride control, stability and handling rather than change it. It installs as a direct-fit rear replacement for the 2016-2018 Mazda CX-9 (see the "Vehicles it fits" section for engine-level details).
KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same OE assembly lines with the same OE-quality components — earning it the OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged, twin-tube design: calibrated to restore original, designed damping performance.
- Triple lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: manage tire contact, steering response and body movement.
- Supports electronic safety systems: helps keep suspension-dependent systems performing as the manufacturer intended.
Worn shocks can show up as excessive bounce, nose dive under braking, body roll or reduced control; if the rear shock is the cause, this Excel-G gas shock replaces it. Sold individually — replace both rear shocks together as a matched pair for balanced ride control.
