Monroe 40423 OESpectrum Front Right Air Strut

The Monroe OESpectrum 40423 is a premium front right air suspension strut engineered as a direct OE replacement. Designed specifically for vehicles originally equipped with active air suspension, this strut delivers a comfortable, controlled ride by isolating impact-related noise, vibration, and harshness.

This active air strut features adjustable compression, adjustable rebound, and adjustable ride height via a threaded air fitting, allowing it to restore and maintain factory-level suspension performance. Monroe's twin-tube internal construction provides efficient damping control across a wide range of road conditions, while the gas charge helps maintain consistent tire-to-road contact and reduces shock fade.
