KYB Suspension Shock Absorber P/N:553385
Restore the rear ride control of your 2012-2020 Chevrolet Sonic with the KYB shock absorber 343459, a nitrogen gas-charged, twin-tube Excel-G damper. 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 using the same OE-quality components — calibrated to restore the vehicle's originally designed control and handling, not to change it. That has earned it KYB's OEA (Original Equipment for the Aftermarket) classification, making this KYB gas shock absorber Excel-G a recommended OEM-style replacement.
Twin-tube gas design: A nitrogen gas-charged, twin-tube layout that includes the same quality components found in KYB's global OEM products.
Triple lip fluid seal: Reduces the chance of oil and gas leaking out for consistent, long-term damping.
Vehicle-specific damping valves: Hand-assembled in-house valving works to correctly manage tire contact, steering response and body movement.
Supports safety systems: Helps keep electronic safety systems performing as designed by maintaining intended suspension behavior.
This is a REAR-position KYB gas shock absorber. Fits the 2012-2020 Chevrolet Sonic — see the Buyer's Guide tab for engine-level detail.
