Achieve the perfect stance and ride balance with the AST Adjustable Lowering Spring Kit for the BMW G21 M340i xDrive and M340i xDrive Plug-In Hybrid. This premium ALS kit allows you to fine-tune your vehicle’s height to your exact preference, offering both aesthetic appeal and enhanced performance without compromising everyday comfort.

Unlike fixed lowering springs, AST’s adjustable design uses precision-engineered height adjusters that let you set your desired ride height even after installation. Developed in the Netherlands using high-grade spring steel and advanced Wafios coiling technology, these springs deliver exceptional durability, consistency, and ride refinement.

The progressive-rate design ensures an ideal balance between comfort and handling — reducing body roll, improving cornering response, and maintaining the refined feel expected from OEM-quality components. Whether you’re after a subtle drop or a sportier stance, AST’s adjustable system provides the flexibility to make your BMW look and perform exactly how you want.
