Designed to help restore the ride control and handling of your Mazda 3, the KYB Excel-G Rear Suspension Shock Absorber 3440133 fits the 2019-2025 MAZDA 3 (see the Buyer's Guide tab for engine-level applications) and installs at the rear as a direct-fit replacement for a worn or leaking original damper. Ride comfort matters, but KYB stresses that restoring stability, stopping, lane-change responsiveness, and handling is what's critical — and the Excel-G is calibrated to bring back original, designed performance rather than change it.
- Nitrogen gas-charged twin-tube design: built on the same KYB OE assembly lines with the same OE-quality components, earning its 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 suspension, brakes, and tires performing as the vehicle manufacturer intended.
KYB positions the Excel-G as the #1 recommended Original Equipment replacement choice for Asian SUVs and crossovers. Sold individually — replace both rear shocks as a matched pair for balanced ride control.
