AST Adjustable Lowering Spring Kit For Mercedes W177 A35 AMG/A45 AMG | ALS Kit

Enhance the stance, comfort, and handling precision of your Mercedes-AMG W177 A35 or A45 with the AST Adjustable Lowering Spring Kit (ALS Kit). Designed and manufactured in the Netherlands, this premium suspension upgrade allows you to precisely fine-tune your vehicle’s ride height for the perfect balance between sporty aesthetics and everyday comfort.

Unlike traditional fixed-lowering springs, AST’s height-adjustable system enables you to modify your vehicle’s height even after installation — giving you complete flexibility to achieve your ideal setup. Crafted using high-grade spring steel and advanced Wafios coiling technology, these springs deliver consistent performance, exceptional ride quality, and long-term durability.

With a progressive-rate design, the springs provide a smoother ride over uneven surfaces while significantly improving stability, turn-in, and body control. Whether you’re refining your daily driver or preparing your AMG for spirited driving, AST’s adjustable spring system provides the ideal OEM+ suspension solution.
