Sachs Suspension Shock Absorber P/N:315 315
Sachs 315 872 rear shock absorber for the 2017-2020 BMW 430i and other vehicles controls rear-axle spring movement after bumps. The SACHS shock absorber is engineered to restore original handling dynamics.
A worn rear shock can show up as the back of the car bouncing after bumps, fluid on the shock body or uneven tire wear. Before you replace it, rule out worn tires, bushings and other rear suspension parts, which can give a similar ride complaint.
The 2017-2020 BMW 430i, the 2017-2020 BMW 440i and the 2017-2020 BMW 440i Gran Coupe are covered, along with many other BMW models. This listing is one shock, and the other side of the same rear axle is normally replaced at the same time. If your BMW is not one of these, look up its year and model in the "Vehicles it fits" section.
One rear shock absorber. The 2017-2020 BMW 430i takes two at the rear axle.
Does the Sachs 315 872 rear shock absorber fit the 2017-2020 BMW 440i?
Yes. Sachs 315 872 is listed for the 2017-2020 BMW 440i, and the same part is listed for the 2017-2020 BMW 440i Gran Coupe.
Is this SACHS absorber sold singly or as a pair?
Singly. This listing is one rear shock, and the rear axle takes two, so the other side is normally replaced at the same time.
Is this a SACHS shock absorber for the rear or the front axle?
Sachs 315 872 is a rear-position shock absorber, so it goes on the rear axle.
How can I tell if my rear shock absorber is leaking or worn?
With the car parked and the engine off, look for fluid on the shock body. A rear end that keeps bouncing after bumps can also mean a worn shock.
What does the application-tuned valve do in this SACHS shock?
This SACHS shock's valve pairing is tuned to the application. It combines service life with ride comfort and control on any road condition.
