Rear Air Spring Kit for 2006-2011 Cadillac DTS

This Unity rear air spring kit replaces worn suspension components on 2006-2011 Cadillac DTS models. The package includes two air spring bags designed to restore the original air ride quality. It is intended for owners seeking to maintain factory ride comfort and handling characteristics.

Verify Fitment and System Condition Before Ordering

Confirm your vehicle is a 2006-2011 Cadillac DTS before purchasing this kit. Inspect existing air lines, fittings, and the compressor for leaks or damage that could affect the new springs. Ensure the suspension control module functions correctly to avoid premature failure of the replacement parts.

Restores Ride Height and Load Support

New air springs maintain proper vehicle height and absorb road irregularities for a smoother ride. The kit supports the rear axle load capacity as specified by the original manufacturer design. Normal operation keeps the compressor cycle frequency within factory parameters for long-term reliability.
