Keep body movement in check and restore the factory ride on your 2019-2022 Toyota Avalon with the KYB Excel-G Suspension Shock Absorber 3440123, a rear-position gas shock built to bring damping back to its original design intent. KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is made on the same OE assembly lines with the same OE-quality components — earning its OEA (Original Equipment for the Aftermarket) classification. It is calibrated to restore the designed control and handling of the Avalon, not to change it.
- Nitrogen gas-charged, twin-tube design: includes every quality component found in KYB's global OEM products.
- Vehicle-specific damping valves: hand assembled in-house to correctly manage tire contact, steering response, and body movement.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Supports electronic safety systems: helps keep them performing as designed, since they depend on the suspension, brakes, and tires operating as the manufacturer intended.
The #1 recommended Original Equipment replacement choice for Asian cars. Sold individually; shocks are best replaced as an axle pair for balanced ride control.
