This pneumatic cylinder assembly is a direct replacement component for the original air spring, which commonly develops leaks, cracks, or compressor failure over time, causing the rear of the vehicle to sag, ride quality to deteriorate, and the air suspension warning light to illuminate.

Q1: What does this air suspension spring do?
A: It replaces the rear left air spring on vehicles with factory air suspension. The air spring supports the rear of the vehicle, maintains ride height, and levels the vehicle under load. A worn or leaking air spring can cause the rear to sag, a harsh or bouncy ride, compressor overwork, and an air suspension warning light.

A: Yes. 48090-35011 is the genuine Toyota/Lexus OEM part number for this rear left air suspension spring. It replaces earlier part numbers 48090-35010 and 48090-35020. It is also available as an OEM-quality alternative from Dorman (949-450) and MAXPEEDINGRODS.
Q3: Will this fit my 2007 Lexus GX470?
A: This air spring is compatible with Lexus GX470 (J120) models from 2003–2009 equipped with factory air suspension. Always verify compatibility using your vehicle's VIN before ordering.
