Deliver controlled, composed rear-axle damping with the Monroe OESpectrum Shock Absorber 39115, a monotube rear suspension shock that drops in as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2020-2025 Mercedes-Benz E350, 2019-2025 Mercedes-Benz E450 and 2019-2023 Mercedes-Benz CLS450 — see the "Vehicles it fits" section for the full list.
- Monotube design: built for vehicles originally equipped with monotube shock absorbers, helping filter out noise, vibration and harshness.
- Consistent ride: high-temperature OE all-weather fluid with special additives to assist in extreme temperatures and help reduce oil breakdown.
- Exceptional handling: full displaced valving adjusts to road extremes, while a free-floating dividing piston separates fluid from the high-pressure gas charge to help reduce shock fade and aeration.
- Control and durability: a PTFE-banded piston maintains consistent sealing against the high-strength pressure tube for better control and longer service life.
A high-pressure nitrogen gas charge helps maintain tire-to-road contact by reducing aeration for improved ride and handling, and a self-lubricating fluid seal retains gas while reducing friction against the piston rod to help limit premature wear. This is a rear-axle shock; signs it may need replacing include excessive bounce, poor ride control, nose-dive under braking, or uneven tire wear. This shock is sold individually; replacing both rear units together as a matched pair is recommended for balanced ride control. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

Frequently Asked Questions
Where does the 39115 shock install?
It's a rear suspension shock absorber for the listed Mercedes-Benz applications. Replacing both rear units together as a matched pair is recommended for balanced ride control.
Which vehicles does it fit?
It fits many vehicles, among them the 2020-2025 Mercedes-Benz E350, 2019-2025 Mercedes-Benz E450 and 2019-2023 Mercedes-Benz CLS450. See the "Vehicles it fits" section to confirm your vehicle.
Is this a monotube shock?
Yes. The OESpectrum monotube design is intended for vehicles originally equipped with monotube shock absorbers, and it uses a free-floating dividing piston and a high-pressure nitrogen gas charge.
How many do I need?
This listing is for one shock. Replacing both rear units together as a matched pair is recommended for balanced ride control.
What are signs my shocks may need replacing?
Excessive bouncing, nose-dive under braking, poor ride control, or uneven tire wear can be signs. Diagnose the cause before replacing, since other components can produce similar symptoms.
