KYB Suspension Shock Absorber P/N:3440073

Bring back controlled, settled ride quality with the KYB Excel-G Gas Shock Absorber (P/N 3440073), a rear damper that installs on the 2018 Buick Regal Sportback and the 2016-2024 Chevrolet Malibu. Built as a KYB-recommended OE replacement, the Excel-G is calibrated to help restore the vehicle's original designed control and handling rather than change it — earning its OEA (Original Equipment for the Aftermarket) classification.

• Nitrogen gas-charged twin-tube design: the Excel-G uses a nitrogen gas-charged, twin-tube construction with the quality components found in KYB's global OEM products.
• Triple lip fluid seal: reduces the chance of oil and gas leaking out.
• Application-tuned damping: vehicle-specific, hand-assembled damping valves are designed to correctly manage tire contact, steering response and body movement.
• Supports electronic safety systems: because those systems depend on the suspension, brakes and tires working as intended, the Excel-G helps keep them performing as designed.

This is a rear shock absorber. Shocks wear as a pair, so replacing both rear units together as a matched set is recommended for even, balanced damping — this listing is for one shock; order 2 for the axle.
