Detailed Description

The Arnott AS-3073 air suspension strut is engineered for the rear right corner of the Lexus LS 430 UCF30 chassis equipped with Height Adjustable Suspension. It is also listed for the LS Ultimate Luxury edition. This part number, AS-3073, is built as a complete new assembly with a hydraulic internal damper, progressive spring rate, and air ride suspension construction to restore proper rear suspension function.

Arnott uses a ContiTech air bladder protected by an aluminum can, along with a CNC-machined aluminum top mount and rubber-coated steel vibration isolator plates. The assembly is made in the USA and uses long-lasting seals, O-rings, a bump stop, an OE-style quick connect air fitting, and a dust boot to help protect the shock. This part cross-references Lexus 4808050110 and 4808050120 for the same application.
