The Blackline Helical Limited Slip Differential (LSD) offers a host of advantages that make it a standout choice for performance and reliability. It ensures equal rotational speed for both wheels while dynamically distributing torque based on traction. With low maintenance requirements—thanks to the absence of clutches—it responds faster than viscous LSDs and provides smooth, progressive engagement with minimal noise. Its 8620 alloy steel construction guarantees strength and longevity, and it serves as a direct replacement for stock differentials.

The Blackline Helical LSD is a torque-biasing system designed to optimize power distribution. By channelling more torque to the wheel with the best traction, it significantly improves performance and drivability, especially in low-grip conditions. The innovative parallel axis helical gears ensure even load distribution. As torque is applied, these gears generate thrust forces proportional to the applied torque, allowing the LSD to handle significant traction imbalances during high-power scenarios like corner exits. At low torque, the system operates smoothly and quietly, making it suitable for everyday road driving.

With a 5:1 torque bias ratio, the Blackline LSD transfers up to five times more torque to the wheel with the most grip, maintaining stability and control. While it functions best when both wheels maintain some traction, techniques like left-foot braking can be used to lock a spinning wheel in rare cases of complete traction loss. Additionally, the system integrates seamlessly with modern anti-lock braking systems (ABS), enhancing precision and safety.

Whether you’re on the road or the track, the Blackline Helical LSD delivers the perfect combination of performance, durability, and drivability.
