Keep the ride controlled and composed with the KYB Excel-G Suspension Shock Absorber 3440053, a nitrogen gas-charged, twin-tube damper that drops in as a direct-fit REAR replacement for the 2013-2019 Cadillac ATS. KYB builds the Excel-G to restore a vehicle's original designed performance rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.
- OE-level design: Nitrogen gas-charged twin-tube construction made with the same OE-quality components KYB supplies to new-vehicle manufacturers, so it helps restore the designed control and handling.
- Triple-lip fluid seal: Reduces the chance of oil and gas leaking out for consistent damping.
- Calibrated valving: Vehicle-specific, hand-assembled in-house damping valves manage tire contact, steering response, and body movement.
- Supports safety systems: Because electronic safety systems depend on the suspension, brakes, and tires working as intended, the Excel-G helps keep them performing as designed.
Worn shocks can show up as excessive bounce, nose dive under braking, or reduced stability — if a failed rear shock is the cause, this replaces it. Shocks work as a pair, so replacing both sides together is recommended for balanced ride control.
