The Blackline limited slip differential for the Porsche Cayman/Boxster 986/987 2.7L BV5/Audi BV5/01X differential, also known as an LSD (Limited Slip Differential), improves traction by distributing torque between the two-wheel drive 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 can thus handle a significant difference in traction between the two wheels, particularly during heavy acceleration out of a turn or when traction is limited.
Under light load, 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 everyday 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 wheel 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. Its effectiveness is therefore optimal when both wheels maintain a minimum amount of resistance.
The Blackline HLF184 limited slip differential is designed for the Porsche Cayman/Boxster 986/987 2.7L BV5 and Audi BV5/01X differential. The number of splines is a critical factor to check before mounting in order to select the version compatible with the vehicle’s transmission. Its housing and gears are made of high-resistance 8620 steel.
