Smooth out bumps and help keep the rear tires planted with the Monroe OESpectrum Shock Absorber 39006, a rear suspension monotube shock designed for vehicles originally equipped with monotube shock absorbers. It drops in as a direct-fit replacement for the rear suspension on a wide range of classic Mercedes-Benz models — including the 1976-1984 300D, 1978-1984 300CD, 1988-1991 300SE, 1986-1991 560SEL and many more; see the "Vehicles it fits" section for the full list of applications.
- Monotube design: a free-floating dividing piston separates the fluid from the high-pressure gas charge to reduce shock fade and aeration, while full displaced valving adjusts to road extremes for a smooth ride.
- High-pressure nitrogen gas charge: helps maintain tire-to-road contact and tight damping response for improved ride and handling.
- PTFE-banded piston: provides consistent sealing against the high-strength pressure tube for better control, increased durability and longer service life.
- High-temperature OE all-weather fluid: contains special additives to handle temperature extremes and help 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. Worn rear shocks can show up as a bouncy or floaty ride, poor body control over bumps and dips, or uneven tire wear — if a failed rear shock is the cause, this replaces it. Sold individually; replacing both rear shocks 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
What is the Monroe 39006?
It's an OESpectrum rear suspension monotube shock absorber built for vehicles originally equipped with monotube shocks, fitting a range of classic Mercedes-Benz models.
What vehicles does the 39006 fit?
The rear suspension of many Mercedes-Benz models, including the 1976-1984 300D, 1978-1984 300CD, 1988-1991 300SE and 1986-1991 560SEL. See the "Vehicles it fits" section for the full list.
Do I need to replace both rear shocks?
This shock is sold individually. Replacing both rear shocks together as a matched pair is recommended for even, balanced ride control.
What does the monotube design do?
A free-floating dividing piston separates the fluid from the high-pressure nitrogen gas charge, which reduces shock fade and aeration for more consistent damping.
What are signs my rear shocks may need replacing?
A bouncy or floaty ride, poor control over bumps and dips, or uneven tire wear. Diagnose the cause before replacing, since these signs can have other sources.
