BMW M550i xDrive Handling Kit - Dinan - Din SBSK - '17-'23. A supplemental ride quality and handling solution engineered to pair with Dinan performance spring sets on the G30 chassis.

Developed for 2017–2023 BMW 540i/M550i xDrive, this kit replaces factory bump stops with carefully tuned, progressive-rate components. By maximizing usable suspension travel on a lowered setup, it helps avoid abrupt bottoming and preserves control over rough pavement. The progressive design also supports the intended spring rate, rewarding the chassis with added mechanical grip and confident cornering while maintaining day-to-day comfort. For best results, install alongside Dinan springs.

Features

• Includes two tuned, progressive-rate bump stops
• OE-quality materials for consistent, durable performance
• Calibrated specifically for use with Dinan springs
• Maximizes compression travel on lowered vehicles
• Helps reduce bottoming and harsh impacts
• Approx. 8.7 hours install time when done alone; minimal added time with springs
