Rear Conversion Kit for Trailblazer and Envoy models

The Unity 65220c Rear Conversion Kit replaces factory air-spring rear suspensions with passive coil-spring components. It fits 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy and related models including Buick Rainier, Isuzu Ascender, Oldsmobile Bravada and Saab 9-7x. The kit is designed for owners who want to eliminate air-ride leaks and compressor failures.

Verify the rear suspension type

Confirm the vehicle originally shipped with an air-ride rear suspension, as this kit only converts that specific setup. Check the year range listed for your exact model, because some trim levels such as the Trailblazer SS or Envoy Denali have narrower fitment windows. The kit does not service front suspension or vehicles that already use coil springs from the factory.

Steel spring components built for long-term

Unity manufactures the kit using steel springs rated for the vehicle’s original load capacity, removing the need for air compressors, height sensors and rubber air bags. The passive design means no electronic recalibration is required after installation, and the solid springs resist sag and leakage over time. Mounting points reuse factory locations, so no frame modification or welding is needed.
