4. FAQ
Q1: Can this air spring be used for right side? A: No. Strictly rear left only. The right air spring has different nozzle angle and positioning structure (OE: 48080-48090), non-interchangeable.
Q2: Need to replace the air compressor together? A: Replace only the air spring if the compressor works normally. If the compressor is overloaded, noisy or overheated for a long time, simultaneous replacement is recommended to extend system lifespan.
Q3: Is professional calibration required after installation? A: Yes. Professional Lexus diagnostic tool is required for chassis height calibration to eliminate fault codes and height deviation.
Q4: Warranty policy? A: 12-month standard warranty. Cover natural cracking and slow air leakage. Exclude collision damage, improper installation and friction wear caused by modified chassis.
Q5: How to confirm vehicle compatibility? A: Verify by 17-digit VIN code or check the OE number printed on the original air spring.
Q6: How is the durability for daily urban use? A: Reinforced cord rubber structure adapts to daily urban SUV load. Avoid sharp object scratches and long-term heavy load parking to extend service life.
