Vehicle Compatibility

This front conversion kit replaces the factory air suspension on 2007 to 2010 Audi Q7 models, 2003 to 2010 Porsche Cayenne models and 2004 to 2010 Volkswagen Touareg models. It is designed for owners who want a passive steel spring setup instead of the original air ride system. The kit does not fit vehicles equipped with electronic suspension, which require a different part number.

Installation Profile

Unity manufactures the kit with over 50 years of aftermarket experience, aiming for a trouble-free installation that restores standard ride height without air compressor or bag maintenance. The conversion removes the complexity of the air system, reducing potential leak points and electronic faults during normal driving.

Long-Term Reliability

The steel spring components are built to withstand the test of time, offering a more reliable suspension alternative that eliminates the ongoing service needs of air bags and compressors. Under sustained use the passive setup maintains consistent ride characteristics without the pressure cycling that ages air suspension parts. The kit is intended as a permanent retrofit rather than a temporary repair.

Questions about this item

How do I install the Unity 31-132500-A Front Conversion Kit on my 2007 Audi Q7?

Remove the air suspension components and fit the passive steel spring assemblies included in the kit, ensuring the upper mount bolts are torqued to the vehicle manufacturer's specification to prevent noise.

What maintenance or replacement will the Unity 31-132500-A kit need over time?

Inspect the steel springs and mounts during routine service intervals for corrosion or sagging; the passive design eliminates air compressor and air bag replacements required by the original system.

What is the first limitation that appears under sustained heavy loading with this kit?

The fixed-rate steel springs will reach their load capacity before an adjustable air system, resulting in reduced ride height and firmer suspension travel under continuous maximum weight.
