Vehicle Compatibility
This rear conversion kit is designed for the 2001-2005 Audi Allroad Quattro. It enables owners to replace the original air suspension with a passive steel spring setup. The kit suits DIY mechanics and professional workshops seeking a permanent fix for failing air ride components. Unity manufactures the parts with over 50 years of aftermarket experience.
Air Ride Replacement
The kit replaces the factory air springs and associated hardware that commonly leak or fail with age. Converting to steel springs removes the compressor, air lines and electronic height sensors from the equation. The jump is worth it when repeated air suspension repairs become costly or when the vehicle sits unevenly overnight. Unity's Elite Suspension Line aims for trouble-free installation.
Long-Term Durability
Steel coil springs do not degrade like rubber air bags and are unaffected by temperature cycles or road salt. The passive design eliminates the compressor duty cycle that causes heat buildup during extended use. Reliability remains consistent whether the vehicle is driven daily or left parked for weeks. The conversion delivers a fixed ride height that will not settle under sustained load.
