Show original supplier description
The ST Suspension X Coilover System is engineered for B6 and B7 Audi A4 Avant Quattro vehicles, offering a significant improvement in handling and aesthetics. Manufactured by KW Automotive, this coilover system utilizes the same valving and technology as the KW Variant 1, but with a durable galvanized steel exterior instead of stainless steel. This design ensures a balance of sporty road performance and everyday comfort. The "X" model provides adjustable ride height, allowing for a lowering range of 1.4 to 2.4 inches on the front axle and 1.4 to 2.6 inches on the rear axle. It features fixed damping settings, simplifying installation and maintenance while delivering a refined driving experience. The galvanized steel construction offers robust protection against corrosion. This kit is specifically designed to fit the following Audi models: B6 (2002-2005) A4 Quattro with 1.8T or 30v V6 engines, and B7 (2005-2008) A4 Quattro with 2.0T or 3.2L V6 engines. The system comes with a 5-year limited warranty to the original purchaser, reflecting ST Suspensions' commitment to quality and durability.
