Smooth out the ride and keep your rear tires planted with the Monroe OESpectrum Rear Suspension Shock Absorber 5664. It's a direct-fit rear shock for the 2013-2019 Cadillac ATS — see the Buyer's Guide tab for engine-level details — designed to help restore the vehicle's original factory drivability and control while filtering out noise, vibration and harshness.

  • Reduced NVH: Twin Technology Active Control System delivers control across most driving conditions while isolating impact-related noise, vibration and harshness.
  • Handling and damping: Full displaced valving tuned specifically to each vehicle adjusts to road extremes, and a larger bore provides more efficient damping control for a smooth, consistent ride.
  • Sealing and durability: A PTFE-banded piston provides consistent sealing between piston and pressure tube for better control and increased durability, while OE all-weather fluid with special additives helps handle extreme temperatures and reduce oil breakdown.
  • Consistent contact: Nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade, and a self-lubricating fluid seal retains gas and reduces friction against the piston rod.

Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
