Arnott A-2949 Air Suspension Spring - Rear

Rear Air Suspension Spring for GX470, 4Runner, Land Cruiser

Arnott A-2949 is a rear air suspension spring for select Lexus and Toyota SUVs. It uses a Continental ContiTech air bladder, heavy-duty crimping rings, and a high-impact plastic resin top mount and bottom piston for a durable OE-style replacement.

Compatible with 2003-2009 Lexus GX470, 2003-2009 Toyota 4Runner, and 2002-2009 Toyota Land Cruiser rear suspension applications, this Arnott NEW air spring is built for vehicles with or without Kinetic Dynamic Suspension. The push-to-connect air fitting swivels 360 degrees, allowing the same spring to replace either side.

Product Details

Arnott’s NEW product line focuses on direct-fit suspension replacements engineered for common OE failure points. A-2949 follows that approach with a rubber bellows design, black sleeve-style construction, a stud upper mount, and a base cup lower mount. It is a rear air suspension spring replacement for the 2003-2009 Lexus GX470, 2003-2009 Toyota 4Runner, and 2002-2009 Toyota Land Cruiser, and it is designed to replace the original rear air spring on both standard and Kinetic Dynamic Suspension-equipped vehicles.

This part cross-references Toyota and Lexus OE numbers such as 4808035010 and 4809035010 for the same application. Arnott A-2949 is a practical choice when servicing rear ride height, air spring sealing, or suspension response on these platforms.

Common Problems This Part Can Address

• Rear end sagging from a worn air spring
• Air leaks caused by aging rubber bellows
• Uneven ride height at the rear of the vehicle
• Compressor cycling caused by loss of air pressure
• Harsh or inconsistent rear suspension performance

Installation Notes

Inspect the air lines, fittings, and surrounding suspension components before installation. Because the fitting swivels 360 degrees, the spring can be positioned for either side during service. Verify rear fitment by model year and suspension configuration before installation on your Lexus GX470, Toyota 4Runner, or Toyota Land Cruiser.
