The AST Lowering Springs are engineered to provide a precise lowering solution for BMW 5 Series models 520i, 523i, 525i, 528i, 530i, and 520D equipped with air suspension (HA) from 06/2004 to 05/2010. Manufactured using state-of-the-art Wafios coiling machines, these cold-coiled springs ensure exceptional quality and durability. Designed to lower the vehicle’s center of gravity effectively, they enhance handling and driving dynamics while maintaining a high level of ride comfort comparable to the original equipment manufacturer (OEM) springs.

The springs feature a progressive design that balances performance improvements with everyday usability, making them suitable for both spirited driving and regular road use. Their tailored fitment ensures direct replacement without the need for modifications, preserving the integrity of your vehicle’s suspension system. The set includes lowering links for the rear, allowing precise adjustment of the rear ride height to achieve optimal stance and performance.

AST’s commitment to quality is reflected in the lifetime warranty against breaking, providing long-term reliability and confidence. These springs are compatible with a wide range of BMW 5 Series vehicles produced between 2004 and 2010, specifically designed to work with air suspension systems. Please note that these springs are not suitable for four-wheel-drive (4WD) vehicles. For cars with existing standard lowering, the effective lowering height will be reduced accordingly.
