37126791675 37126791676 Air Suspension Strut Assembly for BMW 730Li 740Li 750Li 760Li Rear Axle

Q1: What is the difference between 37126791675 and 37126791676?

37126791675 is the Rear Left and 37126791676 is the Rear Right strut. They form a mirror-image pair for the rear axle and must not be interchanged side-to-side.

Q2: Which vehicles does this strut fit?

BMW 7 Series F01 (SWB) / F02 (LWB) and the hybrid versions (F03/F04) equipped with rear self-leveling air suspension — commonly 730Li, 740Li, 750Li, 760Li (from 06/2008). It does NOT fit coil-spring (non-air) suspension models.

Q3: How do I confirm fitment for my car?

The most reliable way is to check the part number by VIN; alternatively read the part number on the original rear strut or provide the vehicle's VIN/nameplate to the seller. Always confirm the side (left/right) and whether the car has EDC (electronic damping).

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

Replacing as a same-axle pair is strongly recommended. A new strut combined with an old one on the other side can cause uneven ride height and damping, affecting stability and ride comfort.

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

Structure and performance 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 rear air strut is leaking or failing?

Common symptoms: ① one corner of the car visibly sagging or settling overnight; ② the air compressor runs frequently or for long periods; ③ a ride-height / suspension warning light on the dash; ④ rear-end noise or harsh ride 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 (or disconnect power and wait for depressurization); ② protect the air line ports and solenoid wiring during removal; ③ after installation, start the car and perform a ride-height reset / system initialization; ④ verify left/right height is even and there is no noise before a road test.

Q8: Is this the EDC (electronic damping) version?

F01/F02 rear air struts come in standard and EDC versions; the EDC version has an electronic damping connector/valve and uses different part numbers — they are NOT interchangeable. Please provide the VIN before ordering to confirm the version and avoid a wrong shipment.

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: If the bellows crack or age, can I replace only the bellows instead of the whole strut?

Yes, but we recommend checking whether the damper has degraded. If the damper is worn, replacing only the bellows will not solve the problem; replacing the complete strut is the more reliable and cost-effective solution (this bellows is also available separately in our store).
