Cusco LSD Type-MZ BK3P 1.5W (1&1.5W)

The Cusco LSD Type-MZ 1.5W differential uses a unique 1.5-way activation system, meaning it engages more aggressively on acceleration than deceleration. This design is favored by many performance drivers because it helps put power down effectively when exiting a corner, while still allowing for a degree of differential action during braking or engine braking. The internal clutch plates are made from a high-friction material, and the unit is designed to handle the stresses of spirited driving and track use. This particular model, the LSD 471 B15, is engineered for specific vehicle applications where improved traction and cornering performance are desired.

Inside the Type-MZ, you'll find a multi-plate clutch system. The 1.5-way mechanism means that when you accelerate, both clutch packs engage to lock the differential, sending power to both wheels. When you lift off the throttle or brake, only one clutch pack engages, allowing for some difference in wheel speed. This balance helps maintain stability under braking while still providing the traction benefits of a limited-slip differential when you need to accelerate out of a turn. The Cusco LSD is a well-built unit designed to be a significant upgrade over a factory open differential, offering a more connected feel and improved control.

When installing a limited-slip differential like this Cusco Type-MZ, it's important to follow the manufacturer's recommended break-in procedure. This typically involves a period of gentle driving and specific fluid changes to ensure the clutch plates seat properly. Using the correct differential fluid is also critical for longevity and performance. This differential is a substantial upgrade for drivers looking to maximize their vehicle's handling capabilities on the track or during spirited road driving.
