Restore controlled, composed rides to the back of your Buick with the KYB Excel-G Gas Shock Absorber (MPN 3440160). This nitrogen gas-charged rear shock is a KYB-recommended OEM replacement for the 2017-2019 Buick LaCrosse, calibrated to restore the vehicle's original designed control and handling rather than change it.

Built on KYB's Excel-G platform — made on the same OE assembly lines using the same OE-quality components — it carries KYB's OEA (Original Equipment for the Aftermarket) classification.

  • Nitrogen gas-charged, twin-tube design: the core Excel-G build preferred by professional technicians.
  • 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 them performing as designed, since they depend on the suspension, brakes and tires working as the manufacturer intended.

If worn rear shocks are behind excessive bouncing, poor ride control or reduced stability, this Excel-G unit replaces them. Sold individually — replacing both rear shocks together as a matched pair is recommended for balanced ride control.

Fitment: 2017-2019 Buick LaCrosse. See the Buyer's Guide tab for engine-level details.
