Blackline Limited Slip Differential - Honda Jazz GK5 1.5 i-VTEC - 2014–2017

The Blackline limited slip differential for the Honda Jazz GK5 1.5 i-VTEC (2014–2017), also known as an LSD (Limited Slip Differential), improves traction by distributing torque between the two-wheel drive systems 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 drive force between the two wheels, particularly during heavy acceleration when exiting a turn or when traction is limited.

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. Its effectiveness is therefore optimal when both wheels maintain a minimum level of resistance. This technology also works particularly well in conjunction with modern ABS systems.

The Blackline HLF091 limited slip differential is designed for the Honda Jazz GK5 1.5 i-VTEC (2014–2017), a model marketed as the Honda Fit in certain markets. It installs as a direct replacement for the original differential on the compatible vehicle. Its housing and gears are made of high-strength 8620 steel.
