KW Coilover Kit V2 BMW 4 Series M440i 4WD xDrive w/o electronic dampers

This KW V2 coilover kit includes the front and rear stainless steel coilover struts, composite spring perches, bump stops with integrated dust protection, and all necessary hardware for installation. It's designed for 2021-2025 BMW 430i xDrive models that do not have electronic dampers from the factory. These coilovers offer a significant step up in performance and adjustability for drivers looking to fine-tune their vehicle's suspension.

The V2 kit utilizes KW's TVR-A (Twin Valve Rebound - Adjustable) technology, allowing you to adjust the rebound damping with 16 precise clicks. This means you can dial in the ride to be firmer for more spirited driving or more comfortable for daily use, all without affecting the compression damping which is pre-tuned by KW's engineers. The stainless steel construction, known as Inox-Line, provides excellent corrosion resistance, ensuring the struts and adjustment collars remain functional and easy to adjust even after years of exposure to the elements. KW develops these damper settings through extensive testing on the Nurburgring and their own 7-post driving dynamics test center, ensuring a vehicle-specific tune that enhances both handling and ride quality.

Beyond the adjustable damping, these coilovers allow for maximum lowering within an approved range, ensuring proper suspension travel and function. The composite spring perches are designed to prevent oxidation and maintain strength, working in conjunction with the stainless steel bodies for long-term durability and ease of adjustment. Each kit is hand-built in Germany and individually serialized, reflecting KW's commitment to quality and performance.
