The Cusco 428 L15 differential is a limited-slip design, meaning it utilizes a mechanism to limit the difference in rotational speed between the left and right wheels.

Meanwhile, the gears are forged from heat-treated steel, providing exceptional strength and resistance to wear and tear.

The Cusco 428 LSD Slip Differential RS-Type also incorporates a unique slip mechanism. This system utilizes a set of clutch plates that engage and disengage, allowing the differential to send power to the wheel with the most traction while allowing the slipping wheel to spin at a slower rate. This not only enhances traction and stability but also helps to prevent wheel hop, ensuring a smoother driving experience.

Installing this differential is a straightforward process, with Cusco providing clear and detailed instructions to guide you through the procedure. Additionally, the unit comes with all necessary hardware, making the installation process as hassle-free as possible.
