48010-50201 48010-50203 Front Air Suspension Strut Lexus LS600h LS460 AWD 2006-2017

Q1: Which OE numbers are for which side? Front Left: 48020-50200, 48020-50201, 48020-50203. Front Right: 48010-50200, 48010-50201, 48010-50203. These are side-specific units — never mix left with right.
Q2: Which vehicles does this fit? Lexus LS460 AWD (4WD) and LS600h / LS600hL (XF40 generation, 2006–2017) with factory air suspension. Amayama's genuine catalog lists LS600H / 600HL (engine 2URFSE); the LS460 4WD application is per the supplier table — confirm by VIN.
Q3: What do the suffixes 50200 / 50201 / 50203 mean? They are successive revision numbers of the same side-specific strut. Per the genuine Toyota catalog, 50203 is the current replacement that supersedes 50200 and 50201. Match the number stamped on your original unit.
Q4: Is this the complete strut or just the air spring? The complete assembly — the genuine catalog name is "CYLINDER ASSY, PNEUMATIC FRONT … W/SHOCK ABSORBER" (pneumatic cylinder with shock absorber), i.e. air spring and damper integrated into one unit, ready to install as a direct replacement.
Q5: Does this strut have electrical damping? The LS460/LS600h air suspension is paired with the factory AVS electronically-controlled damping system — the strut carries the damping control connector. Confirm the connector against the original unit by VIN before ordering.
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 start the car and 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? No aftermarket cross numbers are currently listed in the European/aftermarket catalogs (spareto has no record; amayama lists no aftermarket alternative). For this series, genuine-OEM-style replacement is recommended — order the matched OE number by VIN.
