About Us
FAQ:
Q1: Which OE number is for which side? Rear Left = X01-29150074, Rear Right = X01-29150075. These are side-specific units — never mix left with right.
Q2: Which vehicles does this fit? Li Auto L7 / L8 (from 2023) and L9 (2022-2024) with factory air suspension, per the supplier table. The rear application and L7/L8/L9 fitment are confirmed by multiple independent market listings — confirm the exact model and year by VIN.
Q3: What is the difference from the aluminum-head version? The same rear position also exists as an aluminum-head version (X01-29150078 / X01-29150079). This pack is the plastic-head version (X01-29150074 / X01-29150075) — match the head material to the original unit.
Q4: Is this the complete strut or just the air spring? The complete assembly — air spring (bellows) + shock absorber integrated in one unit with plastic top head, ready to install as a direct replacement.
Q5: Does this strut have electrical damping? The Li Auto L-series factory air suspension pairs air springs with CDC continuous damping control (industry-standard description). The strut therefore carries the damping-control interface — confirm the connector against the original unit by VIN.
Q6: Do I need to replace both rear sides at the same time? Same-axle pair replacement is strongly recommended; an old unit on the other side causes uneven height and leveling behavior.
Q7: What should I pay attention to during installation? Release the air suspension pressure per the workshop manual; protect the air fitting and electrical connector from dirt; after installation let the height control system re-level; check both sides' height and leaks before a road test.
Q8: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.
Q9: Service life and maintenance? Depends on road conditions and climate. Keep the bellows clean and check for cracks during routine service; replace the complete unit if a bellows leak is found.
Q10: Are aftermarket alternatives available? This OE number is not listed in European aftermarket catalogs. Order by the exact OE number and confirm the model/year and side by VIN.
