Blackline Limited-Slip Differential - Mini Classic - Inner Constant-Velocity Joints (Pot Joint)

The Blackline limited slip differential for the Mini Classic with internal constant-velocity joints (Pot Joint), also known as an LSD (Limited Slip Differential), improves traction by distributing torque between the two-wheel drive wheels based on available grip.

Its helical gear design allows the limited slip differential to transmit more torque to the wheel with the best traction. As torque increases, the gears exert pressure against the differential housing and generate the internal friction necessary for this torque distribution. The system thus allows for better utilization of available traction, particularly during heavy acceleration and when exiting corners.

Under light loads, the helical limited slip differential maintains smooth, progressive, and quiet operation. The wheels can continue to rotate at different speeds when necessary, particularly when cornering. This feature enhances traction during spirited driving while maintaining handling suitable for on-road use.

The Blackline limited slip differential uses a parallel-axis helical gear architecture optimized to distribute forces. Its 5:1 torque split means that when one of the wheels loses traction, the wheel with the most traction can receive up to five times the torque transmitted to the spinning wheel.

As with any helical-gear limited slip differential, a minimum amount of resistance must remain on the wheel with the least grip to allow torque transfer. It is therefore most effective when both wheels retain a minimum amount of resistance.

The Blackline HLF072 limited slip differential is designed for Mini Classics originally equipped with inner constant-velocity joints (Pot Joints). This configuration allows the differential to be installed without requiring a specific bevel gear set or special output shafts. The type of drivetrain must be verified before ordering to confirm compatibility.
