Kit contents vary depending on the application. Each kit includes a Blackline helical limited-slip differential together with the components required for that specific upgrade. Depending on the vehicle, this may include differential oil, output shaft seals, or a matched crown wheel and pinion.

Please refer to the individual product listing for the exact kit contents.

Purchasing a complete kit helps ensure the correct components are supplied for your application while saving time sourcing parts separately. Our kits simplify the upgrade process and can provide better value than purchasing each component individually.

Blackline helical limited-slip differentials use precision-engineered helical gears to automatically transfer torque to the wheel with the greatest traction. Unlike plated differentials, they operate without clutch plates, requiring no special servicing while providing smooth, progressive torque transfer for fast road, track day and motorsport use.

Installing a limited-slip differential requires specialist knowledge and the correct setup procedures. Some applications require bearing preload, backlash and gear mesh adjustment to ensure reliable operation. Professional installation is recommended unless you have experience setting up differentials.

It is the installer's responsibility to ensure all components are correctly fitted, adjusted and torqued in accordance with the vehicle manufacturer's specifications and accepted workshop practices. Incorrect installation or setup may result in component failure, vehicle damage or serious injury. Professional installation is recommended.
