Detailed Description

AS-3285 is a rear suspension shock absorber for the 2011-2013 Infiniti QX56, 2014-2024 Infiniti QX80, and 2017-2024 Nissan Armada. It is built as an air-assisted shock with a rubber air bladder, progressive spring rate, and standard-grade twin-tube construction to support controlled rear ride height and damping. The assembly uses a center-eye body end measuring point, a shoulder-of-stud rod end measuring point, and is configured for rear use on vehicles without electronic shocks.

Arnott’s New product line focuses on replacement suspension components built to OE-style ride and fit expectations. AS-3285 follows that approach with premium sealing components, a multi-ply air sleeve, and durable crimping hardware for long-term service in rear air ride systems. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear end sagging from a worn air shock
• Uneven ride height at the back of the vehicle
• Excessive bouncing or reduced damping control
• Air suspension leaks from aging bladder or seals
