FAQ:
Q1: Which OE number is for which side? Front Left = X01-29050017, Front Right = X01-29050018. These are side-specific units — never mix left with right.
Q2: Which vehicles does this fit? Li Auto L7 / L8 / L9 with factory air suspension (plastic-head front strut version). China B2B sources describe "X01-29050017/X01-29050018 Front Ar Suspension Strut for Lixiang Li Auto 7/L8/L9" and explicitly "Lixiang L8". Model launch years: L9 (2022.06), L8 (2022.11), L7 (2023.02) — confirm the exact model and year by VIN.
Q3: What is the difference between the plastic head and aluminum head versions? The same L-series front struts exist in two head versions: plastic head (X01-29050017/018) and aluminum head (X01-29050021/022). Order the version that matches your original unit (the supplier table marks this row as plastic head).
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 front 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.
