The Ultra features Gran Touring suspension, magnetic variable-effort power steering, StabiliTrak stability control, and traction control compared to the base Park Avenue. Stopping power is provided by four-wheel anti-lock disc brakes. The Ultra came standard with chrome-plated 17″ cast-aluminum wheels that were mounted with replacement 235/55 Michelin Defender T+H tires in 2023. The front and rear brake pads and rotors were also replaced at this time.
