Unity Rear Left Air Spring for Cadillac DTS

The Unity 15-540801 rear left air spring is a new suspension component built for 2006-2011 Cadillac DTS models. It restores the air suspension system to provide a safe and comfortable ride. Unity Automotive manufactures the part with over 50 years of aftermarket experience. The Elite Suspension Line aims for trouble-free installation and long-lasting reliability.

Fits 2006-2011 Cadillac DTS rear left corner

This air spring suits owners restoring the factory air suspension on a compatible Cadillac DTS. It is not for vehicles outside the 2006 to 2011 model years or for the right-hand side of the vehicle. Buyers needing a front air spring or a different suspension type should look at other parts. The component addresses the specific rear left position only.

Direct replacement installs with standard tools

Installation follows the original equipment procedure for the rear left air spring. The design targets a trouble-free fit using existing mounting points on the Cadillac DTS. Common issues include reusing worn mounting hardware or failing to inspect the air lines for leaks. Proper torque and a system leak test after fitting help prevent repeat failures.

Questions about this item

Does the 15-540801 rear left air spring require an existing air compressor and air lines to function?

Yes, this air spring is a replacement component for the factory air suspension system. It connects to the vehicle's existing air lines and relies on the onboard compressor to inflate and maintain ride height.

Will this Unity air spring work with the original electronic ride control module on a 2006-2011 Cadillac DTS?

The spring is designed as a direct replacement for the original equipment on those model years. It fits the factory mounting points and works with the vehicle's existing ride control sensors and electronic module.

How can I verify the 15-540801 air spring is operating correctly after installation?

After fitting, start the engine and allow the compressor to run. The rear left corner should rise to the normal ride height, hold that height evenly, and show no air leaks at the fittings or bladder.
