Smooth out the ride and tighten up handling on your Cadillac with the Monroe OESpectrum Front Suspension Shock Absorber 39136. It's a direct-fit front shock for the 2008-2014 Cadillac CTS, built for vehicles originally equipped with monotube shock absorbers to help filter out noise, vibration and harshness. See the Buyer's Guide tab for engine-specific coverage.
- Monotube design: Full displaced valving adjusts to road extremes for a smooth ride, while a free-floating dividing piston separates the fluid from the high-pressure gas charge to reduce shock fade and aeration.
- High-pressure nitrogen gas charge: Helps maintain tire-to-road contact and provides tight damping response for improved ride, handling and vehicle control over bumps, dips and potholes.
- PTFE-banded piston: Delivers consistent sealing against the high-strength pressure tube for better control, increased durability and longer service life.
- All-weather OE fluid: High-temperature fluid with special additives assists in extreme temperatures and helps reduce oil breakdown for a consistent ride.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod to help limit premature wear. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Replace worn shocks in matched pairs across the axle for balanced handling.

What is a monotube shock?
A monotube design uses a free-floating dividing piston to separate the fluid from a high-pressure gas charge, which helps reduce shock fade and aeration for more consistent damping.
Should I replace shocks in pairs?
Replacing both front shocks together as a matched pair is recommended for balanced handling and even wear. This listing is for one shock.
What are signs my shocks may need replacing?
Common signs include excessive bouncing over bumps, nose dive when braking, uneven tire wear, or fluid leaking from the shock body. Diagnose the cause before replacing.
