Front Air Suspension Strut Shock Absorber BMW G11 G12 EDC 37106877557 37106881061

Q1: Which OE numbers are left and which are right?

37106877557 / 37106881061 are the Front Left side; 37106877558 / 37106881062 are the Front Right side. They are the same application under different/superseded OE numbers — match the number on your original part, and never mix left with right.

Q2: Which vehicles does this fit?

BMW 7 Series G11 (SWB) / G12 (LWB), approx. 2015–2022, xDrive (4WD) models equipped with front air suspension and EDC (electronic damping control) — commonly 740i xDrive, 740Li xDrive, 750i xDrive, 750Li xDrive, 760Li xDrive, M760Li. Per the supplier listing, this set of OE numbers corresponds to the "4 Matic" variant; RWD-only vehicles without air suspension or without EDC do NOT fit. Always confirm by VIN.

Q3: How do I confirm fitment for my car?

Check the part number by VIN in a BMW EPC catalog, or read the part number on the original unit and confirm it is one of the numbers listed above. Provide the VIN to the seller before ordering to confirm the side (left/right), the drive type (RWD/xDrive) and that the car has EDC.

Q4: Do I need to replace both front sides at the same time?

Replacing as a same-axle pair is strongly recommended. An old unit on the other side may cause uneven ride height, damping and leveling behavior, affecting handling and comfort.

Q5: How is this different from the genuine BMW part?

Structure, spring rate and damping calibration match the OE specification and are tested to original standards. The main differences are the price (far lower than dealer) and the supply channel. Core components use durable materials — this is not a low-grade substitute.

Q6: How do I know the front air shock is failing?

Common symptoms: ① the front of the car sags or settles overnight; ② the air compressor runs frequently or for long periods; ③ a ride-height / suspension warning light or EDC fault code on the dash; ④ knocking or harshness from the front suspension while driving. Replace as soon as possible once these appear.

Q7: What should I pay attention to during installation?

① Jack up the vehicle and release the air suspension system pressure per the workshop manual; ② disconnect the air line and the EDC electrical connector carefully; ③ mount the new unit, reconnect the air line and EDC connector, and ensure the connector is fully seated; ④ start the car and perform a ride-height reset / system initialization; ⑤ verify left/right height is even and there is no leak before a road test.

Q8: This unit has EDC — is that different from a normal air shock?

Yes. The EDC version has an electronic damping control connector that adjusts damping according to driving mode. It is designed for vehicles with the EDC system and must not be replaced with a non-EDC unit. If a suspension warning stays on after replacement, run a diagnosis (e.g., ISTA) and clear/adapt the system as needed.

Q9: What is the warranty policy? What about shipping damage?

18-month warranty under normal use. For shipping damage, inspect the package within 48 hours of receipt and send photos/video — the seller will arrange a replacement.

Q10: How long do these units last, and can I maintain them?

Service life depends on road conditions and climate; keeping the bellows clean and checking for cracks during routine service helps extend life. If the bellows crack or leak, replacing the complete unit is the most reliable and cost-effective solution.
