ST 27310049 Coilover Spring Kit AUDI A6; (4F) 05/04- FA 25-55 RA 25-55

ST 27310049 Height-adjustable springs kit (lowering springs)

The ST suspensions coil springs convert the OEM suspension into a height-adjustable setup while retaining the factory dampers. Thanks to the ST threaded sleeves, the system is compatible with vehicles equipped with either welded or clipped spring perches on the original dampers. On applicable vehicles, the use of electronic damper control can also be retained.

The springs are engineered with vehicle-specific spring rates to match the characteristics of the OEM dampers and provide a balanced combination of lowering and driving dynamics. The adjustable lowering range allows a precise ride height setup, while the lower center of gravity improves steering response and reduces body roll during rapid directional changes and cornering.

Manufactured in OE quality from high-strength chrome-silicon steel, the springs are cold-coiled, heat-treated multiple times, and finished with an epoxy coating. This construction ensures high durability, resistance to sagging, and reliable performance in varying weather conditions.
