48080-48030 48080-48010 Rear Air Suspension Strut Lexus RX300 RX330 RX350 Harrier 4WD

Q1: Which OE numbers are for which side? Rear Left: 48090-48030, 48090-48010. Rear Right: 48080-48030, 48080-48010. These are side-specific units — never mix left with right.

Q2: Which vehicles does this fit? Toyota Harrier 4WD and Lexus RX300 / RX330 / RX350 (XU30 platform) with factory air suspension. Amayama lists RX300 / RX330 / RX350 + Toyota Harrier (engines 1MZ-FE, 3MZ-FE, 2GR-FE). Model years: RX300 (2003), RX330 (2004–2006), RX350 (2007–2009); Harrier XU30 (2003–2013) — confirm by VIN.

Q3: What do the suffixes 48030 / 48010 mean? They are successive revision numbers of the same side-specific rear strut. Per the genuine Toyota catalog, 48010 is the current replacement that supersedes 48030. 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 REAR … 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? This RX/Harrier air suspension provides rear height / load-leveling control; whether your specific unit carries an electronic damping connector depends on the original equipment — confirm against the original unit by VIN before ordering.

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 any 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 (amayama lists no aftermarket alternative for this series). For this series, genuine-OEM-style replacement is recommended — order the matched OE number by VIN.
