Upgrade your BMW's 210mm large case differential with this complete performance package, featuring a Blackline helical limited-slip differential and Motul high-performance racing gear oil. Designed for fast road, track day, and performance applications, this package significantly improves traction, stability, and power delivery compared to the factory open differential.
The Blackline helical LSD is engineered specifically for BMW models fitted with the 210mm large case differential. Using a precision torque-biasing helical gear design, it automatically transfers torque to the wheel with the greatest available grip, helping to reduce wheelspin and maximise traction during acceleration and cornering. Unlike clutch-type differentials, there are no clutch plates to wear out, resulting in smooth, progressive operation with minimal maintenance requirements.
With a 5:1 torque bias ratio, the Blackline LSD can transfer up to five times more torque to the wheel with the most traction, improving vehicle control and confidence in both dry and low-grip conditions. Manufactured from high-strength 8620 alloy steel and precision heat-treated for durability, it is built to handle the demands of high-performance road and motorsport use.
To complement the differential, this package includes Motul high-performance racing gear oil, specially formulated for limited-slip differentials and high-load drivetrain applications. Designed to withstand extreme temperatures, shock loads, and heavy torque demands, it provides exceptional lubrication and protection while ensuring smooth and consistent differential operation.
Key benefits include:
- Improved traction and acceleration
- Reduced inside wheel spin when cornering
- Enhanced vehicle stability and control
- Smooth, progressive torque transfer
- No clutch plates to wear or service
- Quiet operation suitable for road and track use
- Premium Motul racing gear oil included
- Outstanding protection against heat, wear, and extreme loads
Designed specifically for BMW 210mm large case differential applications, this package provides a complete solution for enthusiasts looking to improve both performance and reliability.
