Cusco LSD 431 K2 Type-MZ Limited Slip Differential 2-Way Rear LSD

The Cusco LSD 431 K2 is a Type-MZ limited slip differential engineered for high-performance street and race applications. This mechanical LSD is designed specifically for the 2016+ Mazda MX-5 Miata (ND chassis) rear differential, delivering superior traction and control in demanding driving conditions.

Type-MZ Technology:

The Type-MZ design utilizes cone spring activation where pressure opposes the direction of initial torque, creating the highest rated initial torque of any Cusco LSD model. The high-pressure cone spring engages the full clutch pack lock at a linear rate, providing aggressive and immediate response ideal for race applications. This unit features an upgraded 10-plate clutch pack (five plates per side) compared to conventional 8-plate designs, significantly increasing locking performance and power handling capability.

Key Features:

• 2-Way configuration with 1.5-Way & 2-Way adjustability without additional components
• Enhanced clutch pack with 10 plates for superior locking performance
• Oil Through System with forged components for optimal lubrication and durability
• Radially-cut clutch plate grooves for instant oil movement and improved efficiency
• Polished pressure ring contact surfaces for even clutch plate engagement
• Chromoly steel casing and gears for maximum strength and durability
• Adjustable responsiveness through plate stacking configuration

2-Way Operation:

The 2-Way configuration activates the LSD on both acceleration and deceleration, making it ideal for rear-wheel-drive vehicles and aggressive driving styles including drifting and circuit racing. The pressure ring features dual profiles allowing conversion between 1.5-Way and 2-Way settings to match your driving preference and application.

Designed for drivers seeking maximum performance and control, the Cusco Type-MZ LSD delivers track-proven results backed by decades of motorsports experience. Professional installation and use of Cusco LSD oil is recommended for optimal performance and longevity.
